Skin Care Glossary

Acetyl Mandelic Acid

An Alpha Hydroxy Acid derivative that helps to increase nail cell retention and increase nail strength. Used in acne formulations to exfoliate skin.

Acne

Acne and blemishes can occur on the face, back and chest. Your skin fits this condition if you have excess oil and shine a few hours after washing, regular acne breakouts monthly or in response to stress, or if you have at least one acne pimple and/or bothersome blackheads and whiteheads on a regular basis. Cleansers and toners need to be carefully selected so as not to irritate or dry the skin which may stimulate over production of sebum by the sebaceous glands. Use of oil-free moisturizers is suggested to keep skin hydrated without clogging pores. Topical acne treatments can be used to clear acne pimples, blackheads and whiteheads and to help prevent new acne pimples from forming. If you have deep acne cysts or regularly have more than 10 pimples at one time, then you should see a dermatologist for additional anti-acne therapy. For product recommendations, visit our Oily/Acne-Prone category.

Acne-Prone

If you have excess oil and shine a few hours after washing, and are prone to acne breakouts monthly or in response to stress, your skin is considered acne-prone. Cleansers and toners need to be carefully selected so as not to irritate or dry the skin which may stimulate over production of sebum by the sebaceous glands. Light, oil-free moisturizers should be used to keep skin hydrated without being oily. Use acne treatment products to clear acne pimples, blackheads and whiteheads and to help prevent new pimples from forming. For product recommendations, visit our Oily/Acne-Prone category.

Active Charcoal

Specially processed charcoal powder for topical use in skincare. The porous and adsorptive charcoal particles attract environmental toxins such as pollution and dirt allowing them to be easily washed away, preventing further damage to the skin. This ingredient can be found in Exuviance Detox Mud Treatment.

Adjunctive to Retinoid Therapy

Many people use physician prescribed medications and cosmetic procedures to correct their more serious skin care problems. Prescription retinoids (Retin-A, Renova, Avage, Ziana, Differin, and Tazorac) are regularly used to treat acne and photoaging. Cosmetic procedures including microdermabrasion, laser and superficial chemical peels (lunchtime peels) are increasingly being used to provide softer, smoother, firmer skin to fight photoaging, and clinically to help reverse acne scarring and pigmentation irregularities. In order to maximize benefits to any professional cosmetic program, a safe and effective skin care regimen should be used at home. Our studies show that PHAs are compatible and useful in combination with retinoids. Furthermore, many skin care professionals recommend using AHAs / PHAs at home between cosmetic procedures to enhance the effects of cosmetic procedures. For product recommendations, visit our Pre/Post Procedure category.

Age Spots

Your skin is 'hyperpigmented' or 'uneven' if you have areas of discoloration on your face, chest, shoulders or hands from years of sun exposure. Also known as sun spots, age spots and liver spots, these areas of hyperpigmentation are visible signs of photoaging. Skin may also become discolored after pregnancy or as a result of using oral contraceptives (birth control pills); this condition is called 'melasma or chloasma'. Many cases of melasma and hyperpigmentation will improve over time with regular use of a topical skin lightener and exfoliator. Some cases of hyperpigmentation occur deeper in the skin and require a dermatologist to provide additional therapy. All pigmentation problems require sun avoidance and or strict sunscreen use to maintain benefits of treatment. For product recommendations, visit our Dark Spots/Discolorations category.

Alpha Hydroxy Acids (AHAs)

Alpha Hydroxy Acids (AHAs) are weak organic acids found naturally in foods and include Glycolic Acid, Lactic Acid, Mandelic Acid and Citric Acid, to name a few. AHAs exfoliate surface cells and encourage cell renewal. Studies with AHAs have also reported important antiaging benefits including increased collagen, improved elastic fiber quality and an increase in water-binding glycosaminoglycans (GAGs). Collectively, these effects result in more even pigmentation, smoother, firmer skin, and a diminished appearance of fine lines, wrinkles and other outward signs of photoaging. Topical formulations incorporating AHAs are frequently used or prescribed by dermatologists for antiaging and other conditions and are also present in a wide range of cosmetic products. In addition to providing antiaging benefits, AHAs are often used adjunctively with therapeutic regimens designed to treat acne, pigmentation, melasma, dry skin and other skin conditions. AHAs quickly penetrate the skin, and in some cases can produce temporary stinging and burning. In individuals who are sensitive to these sensations, it is recommended to start slowly and gradually increase concentration of AHAs as the skin can tolerate.

In addition to these proven antiaging benefits, AHAs are often used adjunctively with therapeutic regimens designed to treat acne, pigmentation, melasma, dry skin and other skin conditions.

Atopic Dermatitis

These clinically sensitive skin conditions 'over' respond to normal environmental and social factors. Atopic skin is extremely sensitive to any topical products, including normal cleansers and moisturizers, and often appears irritated and red. It is often difficult to identify a normal skin care regimen that does not irritate atopic skin, especially one that contains antiaging ingredients. Rosacea is an inflammatory condition that some researchers believe is caused or worsened by a microorganism on the skin, which makes the nose and surrounding areas appear very red and inflamed, and often shiny and broken out. Those prone to rosacea may experience a flare after drinking a glass a wine, going outside into cold weather, feeling embarrassed and flushed, drinking hot fluids or eating spicy foods. There are many different situations that cause a flare in rosacea, including using many skincare and cosmetic products. The Polyhydroxy Acid (PHA) Gluconolactone, is compatible with atopic dermatitis and rosacea, and provides the antiaging benefits expected from an AHA. For more information, visit Clinical Studies.

An organic and chemical sunscreen that absorbs a wide spectrum of UVA rays.

Caffeine

An ingredient found naturally in coffee that helps reduce skin puffiness when applied topically.

Chapped

Dry skin conditions are usually mildly dry with light flaking and skin tightness. Most dry, chapped skin can be relieved through the use of a good moisturizer with AHAs and PHAs for gentle exfoliation, moisturization and skin conditioning. More bothersome dry skin conditions on the face require an extra heavy emollient formulation in combination with skin normalizing/conditioning Alpha and Polyhydroxy Acids (AHAs and PHAs). The most severe forms of dry skin including ichthyosis and plaque psoriasis, generally require therapeutic products, and are best treated by a dermatologist. For product recommendations, visit our Sensitive/Dry category.

Chelator

A chelator is functional cosmetic ingredient that traps metals. Antioxidant chelators trap metals that promote oxidation in skin. Lactobionic Acid, Maltobionic Acid and Gluconolactone are antioxidant chelators found in Exuviance products.

Citric Acid

Citric Acid, found naturally in citrus fruits, is a powerful Alpha/Beta Hydroxy Acid that has preventative antioxidant and corrective antiaging effects, helping to minimize the damaging effects of the sun and pollution and reverse signs of photodamage and solar elastosis. Clinical studies show Citric Acid provides significant antiaging benefits including building the skin's matrix to plump and firm skin. Citric Acid formulations help reduce the appearance of fine lines and wrinkles and increase skin firmness. Because it has both preventative antioxidant and corrective antiaging effects, it is often used as a booster to target specific skin concerns. For product recommendations, visit our Citric Acid category.

CitraFill®

CitraFill® is a patented ingredient technology from Exuviance that targets skin's natural collagen in order to help plump and firm skin's appearance.

Citric Acid helps build the hydrating matrix to make lines visibly appear fuller and more youthful. For product recommendations, visit our CitraFill category.

Combination Skin

Your skin is classified as 'combination' if you experience oiliness and shine in the T-zone (forehead, nose and chin) a few hours after washing, while having normal or dry skin on the cheeks and along the jaw line. Your skin may also be combination if you feel dry, tight and in need of moisturization after washing in the morning, and then progress to an oily or shiny appearance a few hours later. For product recommendations, visit our Normal/Combination category.

Cosmetic Procedures: Laser, Microdermabrasion, and Superficial Chemical Peels

Many use physician prescribed medications and cosmetic procedures to correct more serious skin care problems. Prescription retinoids (Retin-A, Renova, Avage, Ziana, Differin, and Tazorac) are regularly used to treat acne and photoaging. Cosmetic procedures including microdermabrasion, laser and superficial chemical peels are used to provide softer, smoother, firmer skin to fight photoaging, and clinically to help reverse acne scarring and pigmentation irregularities. In order to maximize benefits to any professional cosmetic program, a safe and effective skin care regimen should be used at home. Our studies show that PHAs are compatible and useful in combination with retinoids. Furthermore, many skin care professionals recommend using AHAs/PHAs at home between cosmetic procedures to enhance the effects of cosmetic procedures. For product recommendations, visit our Pre/Post Procedure category.

Dermatologist Tested/Allergy Tested

Products were tested on people under the direction of a dermatologist to ensure they are non-irritating and non-allergenic.

Dry

Dry skin conditions range from mildly dry with light flaking and skin tightness to extremely rough hyperkeratotic disorders. Most dry skin can be relieved through the use of a good moisturizer with AHAs and PHAs for gentle exfoliation, moisturization and skin conditioning. The more bothersome dry skin conditions on the face require an extra heavy emollient formulation in combination with skin normalizing/conditioning Alpha and Polyhydroxy Acids (AHAs and PHAs). The most severe forms of dry skin including ichthyosis and plaque psoriasis, generally require therapeutic products, and are best treated by a dermatologist. For product recommendations, visit our Sensitive/Dry category.

Dull

Nearly all of the visible signs of aging are due to accumulated sun exposure. This condition, known as photoaging, causes the appearance of wrinkled, dull and lifeless skin on sun exposed areas of the body. The Alpha Hydroxy Acids, including Glycolic Acid and the Polyhydroxy Acids including Gluconolactone and Lactobionic Acid, along with daily sunscreen usage have been shown to help reverse some of the visible signs of photodamage. Repeated use makes the skin texture smooth with a reduced appearance of fine lines and wrinkles. AHAs also improve skin brightness and luminosity, helping to revitalize dull, lifeless skin. AHA products which are combination sunscreen plus moisturizers are recommended for daytime use. More intense corrective therapies are available from dermatologists and plastic surgeons as well as other skin care professionals. These include superficial peels, retinoids, lasers and dermabrasions. For product recommendations, visit our Texture & Tone category.

Eczema

These clinically sensitive skin conditions 'over' respond to normal environmental and social factors. Atopic skin is extremely sensitive to any topical products, including normal cleansers and moisturizers, and often appears irritated and red. It is often difficult to identify a normal skin care regimen that does not irritate atopic skin, especially one that contains antiaging ingredients. Rosacea is an inflammatory condition that some researchers believe is caused or worsened by a microorganism on the skin, which makes the nose and surrounding areas appear very red and inflamed, and often shiny and broken out. Those prone to rosacea may experience a flare after drinking a glass a wine, going outside into cold weather, feeling embarrassed and flushed, drinking hot fluids or eating spicy foods.

Gardenia Cell Culture Extract

Derived from a tropical evergreen shrub native to Southern Asia, this extract helps build and protect collagen.

Glucoheptonolactone

A plant-derived Polyhydroxy Acid that is hydrating and provides antioxidant chelation effects.

Gluconolactone

Gluconolactone, a Polyhydroxy Acid found naturally in the skin, contains water-attracting hydroxyl groups to condition and hydrate the skin. It provides full strength antiaging benefits without irritation, even for patients with clinically sensitive skin or rosacea, or those who have had cosmetic procedures. Gluconolactone strengthens skin's barrier function, reducing sensitivity to irritants and skin redness over time. As an antioxidant, Gluconolactone inhibits elastase to preserve healthy tissue and maintain skin's youthful elasticity, resulting in smoother texture and a diminished appearance of lines and wrinkles.

Glycation

Protein glycation is one of many natural aging processes that occurs in skin. Caused by a reaction between a sugar (glucose) and proteins such as collagen, glycation leads to the formation of irreversible and highly-detrimental Advanced Glycation End-products (AGEs). An increase in AGEs results in undesired cross-linking of collagen, ultimately causing wrinkles and a sallow/yellow appearance. Anti-glycation is considered an important antiaging step in the maintenance of healthy, youthful skin. In order to prevent the formation of AGEs, some cosmetic compounds function as antioxidants/chelators. The Bionic Acids, including Lactobionic and Maltobionic Acids, and the Polyhydroxy Acid, Gluconolactone, have antioxidant and metal chelation properties, and have been shown to reduce glycation, as well to improve the appearance of sallow, photoaged skin. Shop Exuviance Age Less Everyday.

Glycolic Acid

Glycolic Acid (an AHA) is a fruit acid derived from sugar cane. It is the smallest molecule of the AHA family, and readily absorbs into the skin, enhancing exfoliation to remove the dead, dull surface cells for a fresher appearance. Due to the quick absorbance into the skin, stinging and burning sensations may be experienced by those individuals who are sensitive. This AHA also helps increase glycosaminoglycans (GAGs) and collagen fibers, for skin that appears firmer. Glycolic Acid has proven antiaging benefits and has also been used to reduce the appearance of acne, pigmentation, melasma and other skin conditions. It improves the skin's radiance and texture, and helps smooth the skin and reduce the appearance of fine lines and wrinkles for healthier, younger looking skin. For product recommendations, visit our Glycolic Acid category.

Glycosaminoglycans (GAGs)

Glycosaminoglycans (GAGs) are produced by the body to help cushion cells and provide hydration to the skin. The amount of GAGs in the skin declines with age and exposure to sunlight. Hyaluronic Acid is the most commonly known GAG in skincare, it is a natural component of the skin's dermis, and it has the unique ability to bind many times its weight in water making it extremely hydrating. By building skin's GAGs, the skin becomes more plump, helping to reduce the appearance of wrinkles from the inside out.

Grape Seed Extract

A potent antioxidant derived from Chardonnay Grape Seeds that is used to help protect skin against free radicals.

Green Tea Extract

Green Tea Extract contains EGCG, a naturally occurring Polyphenol flavonoid with potent antioxidant effects. It is used topically as an antioxidant to help protect the skin against damaging free radicals from sunlight, which cause cellular damage and premature aging. Studies show green tea extract neutralizes free radicals, helps protect skin cells and reduces inflammation. Green tea extract is a great antioxidant to help fight oxidative damage to skin.

Hormonally Reactive

'Sensitive' skin occurs from time to time in a majority of women, and each condition is as individual as the person experiencing it. While each person's condition is unique, the general condition is characterized by heightened sensory responses to chemical, environmental or social triggers. People with sensitive skin are more likely to experience stinging, itching, burning, dryness, redness and breakouts in response to their skin's particular trigger. Many people with sensitive skin experience mild stinging and burning from soaps and cleansers as well as Alpha Hydroxy Acids (AHAs) such as Glycolic or Lactic Acid. The Polyhydroxy Acid (PHA) Gluconolactone provides the benefits of AHAs without the potential for stinging and burning even the most sensitive skin. If your skin sensitivity increases or becomes troublesome, you should visit a dermatologist since it could be a more serious skin condition requiring professional care. For product recommendations, visit our Hormonal/Menopausal category.

Humectant

Ingredients that attract water. They are used to retard the loss of water from a cosmetic product and to provide moisturization to the skin.1

Hyaluronic Acid

Hyaluronic Acid is a water-binding glycosaminoglycan (GAG) found throughout the body including in the joints and skin and is a key component of human connective tissue. In skin, it forms a hydrating gel matrix that plumps the skin and targets the collagen and elastic fiber network. Hyaluronic Acid is comprised of Glucuronic Acid (a Polyhydroxy Acid) and N-acetyl glucosamine. Topical application of N-acetyl Glucosamine has been shown to help increase natural Hyaluronic Acid, which plumps and smoothes the appearance of wrinkles. For product recommendations, visit our Hyaluronic Acid category.

A skin lightening ingredient approved by the US Food and Drug Administration (FDA). It lightens skin by helping to reduce the production of melanin / pigment.

Hyperkeratotic

Dry skin conditions range from mildly dry with light flaking and skin tightness to extremely rough hyperkeratotic disorders. Most dry, chapped skin can be relieved through the use of a good moisturizer with AHAs and PHAs for gentle exfoliation, moisturization and skin conditioning. The more bothersome dry skin conditions on the face require an extra heavy emollient formulation in combination with skin normalizing/conditioning Alpha and Polyhydroxy Acids (AHAs and PHAs). The most severe forms of dry skin including ichthyosis and plaque psoriasis, generally require therapeutic products, and are best treated by a dermatologist. For product recommendations, visit our Dry/Scaly category.

Hyperpigmented

Your skin is 'hyperpigmented' if you have areas of discoloration on your face, chest, shoulders or hands from years of sun exposure. Also known as sun spots, age spots and liver spots, these areas of hyperpigmentation are visible signs of photoaging. Skin may also become discolored after pregnancy or as a result of using oral contraceptives; this condition is called 'melasma'. Many cases of melasma and hyperpigmentation will improve over time with regular use of a topical skin lightener and exfoliator. Some cases of hyperpigmentation occur deeper in the skin and require a dermatologist to provide additional therapy. All pigmentation problems require sun avoidance and or strict sunscreen use to maintain benefits of treatment. For product recommendations, visit our Dark Spots/Discolorations category.

Hypoallergenic

A product that is non-irritating and non-allergenic. This claim is made on the basis of our clinical data supporting non-irritating claims with PHAs and bionic Acids, and patch testing of products, which is conducted under the direction of a dermatologist.

Keratosis Pilaris

Keratosis Pilaris (KP) is a skin (follicular) condition that appears as rough bumps around hair follicles (goose-bump like appearance) on the skin of the back and outer side of the upper arms and thighs. KP is typically most developed and noticeable in adolescent females. KP is an extremely common condition that can be cosmetically troubling but is not harmful in a medical sense. The condition is benign, self-limiting, and disappears with increasing age. The bumps result from the improper shedding of scales from the skin in and around the affected hair follicles. Keratosis pilaris tends to be more severe during the winter months or other times of low humidity. It occurs because as the skin renews itself, old skin cells in the affected hair follicles get stuck, forming a scaly plug because the old skin cells are excessively adherent and do not shed easily. Each bump is a horny plug, sometimes red but only rarely itchy. The scale buildup often entraps the hair within the follicle.

Treatment of KP using moisturizing and exfoliating creams and lotions with high strength AHA or urea products may be helpful. They generally need to be applied at least twice daily and work by softening and reducing cell cohesion of the adherent skin scales around the follicle enabling them to be shed more easily. Often the use of an exfoliating washing device such as a poof to apply the cleansers and creams and to exfoliate the skin increases the benefits of these products. In many cases, skin returns to its pretreatment character if treatment is discontinued. Therefore people who are prone to this condition usually benefit from the regular use of these exfoliating moisturizing products as part of their skincare regimen.

If you think you may have keratosis pilaris and are not being helped by exfoliants you can seek the advice of your dermatologist or other physician. For product recommendations, visit our Keratosis Pilaris category.

Kojic Acid

PA++++

Sunscreens provide protection from ultraviolet (UV) radiation from the sun. The Sun Protection Factor (SPF) is a measurement of how much protection the sunscreen offers from the UVB rays that cause sunburn. The Protection Grade of UVA (PA) ranking refers to the amount of protection the sunscreen offers from the UVA rays that cause skin aging and other skin damage. PA rankings are listed from a '+' signifying low protection to '++++' for the highest protection. It is important to protect the skin across the UVA and UVB spectrum to help prevent sunburn and decrease the risk of skin cancer and early skin aging. Exuviance Sheer Daily Protector SPF 50 provides protection from both UVA and UVB rays with the highest protection grade of PA ++++ and an SPF 50.

Panthenol / Pro-Vitamin B5

A humectant that improves hydration and helps soften and soothe the skin.

Parabens

Parabens are preservatives that are widely used in cosmetic and skin care products. It is important to use preservatives to prevent contamination and microbial growth with repeated use. However, consumers are asking more questions about parabens and on occasion request paraben-free formulations. As a result, we are actively researching paraben-free alternatives and are committed to providing new formulations that are paraben free.

Peptides

Peptides play a key role in rejuvenating skin, including collagen, and its surrounding support. Targeting lost collagen can help fill and plump the skin so it appears firm, lifted and toned, with a smoother appearance of lines and wrinkles. For product recommendations, visit our Peptides category.

Photoaged / Photodamaged

Nearly all of the visible signs of aging are due to accumulated sun exposure. This condition, known as photoaging, causes the appearance of wrinkled, dull and lifeless skin on sun exposed areas of the body. The Alpha Hydroxy Acids, including Glycolic Acid and the Polyhydroxy Acids including Gluconolactone and Lactobionic Acid, along with daily sunscreen usage have been shown to help reverse some of the visible signs of photodamage. Repeated use makes the skin texture smooth with a reduced appearance of fine lines and wrinkles. AHAs also improve skin brightness and luminosity, helping to revitalize dull, lifeless skin. AHA products which are combination sunscreen plus moisturizers are recommended for daytime use. More intense corrective therapies are available from dermatologists and plastic surgeons as well as other skin care professionals. These include superficial peels, retinoids, lasers and dermabrasions. For product recommendations, visit our Discoloration and Anti-aging categories.

Polyhydroxy Acids (PHAs)

Polyhydroxy Acids (PHA) are a special type of AHA (Alpha Hydroxy Acid) known to modulate keratinization, normalize stratum corneum exfoliation and thickness, and strenghten skin barrier function without irritating skin. For this reason, PHAs offer a distinct advantage over conventional AHAs (Glycolic Acid and Lactic Acid) when used on sensitive skin, such as rosacea, atopic dermatitis, and eczema. In addition, due to the additional hydroxyl groups on the molecule, PHAs appear to attract more water through hydrogen bonding, and therefore provide enhanced moisturization to the skin. Many Polyhydroxy Acids including Gluconolactone and Lactobionic Acid have also been shown to function as antioxidants through chelation of oxidation promoting metals and thus can inhibit the oxidation of other food and drug substances and this property may prove beneficial in the prevention of photoaging.

Preservative

Ingredients which prevent or retard the growth of microorganisms and thus prevent the spoilage of cosmetic products. Spoilage can occur as a result of contamination from the manufacturing process, or through repeated exposure to the environment during normal use. 1

Prodew®

Prodew® provides these crucial amino Acids building blocks of skin's own NMF and restores deep reservoirs of plumping moisture. Prodew® is a registered trademark of Ajinomoto.

Retinol

Retinol is Vitamin A. It is a precursor to the prescription retinoid known as retinoic Acid (Retin-A®), but is better tolerated by the skin. It provides many antiaging benefits to skin, including increased skin thickness as well as reduced appearance of uneven pigmentation. Studies show that retinol works synergistically with NeoGlucosamine® to increase the skin’s hydrating gel matrix, which helps to build volume from the inside out to plump and firm skin, reducing the appearance of fine lines and wrinkles. It is also an antioxidant to fight free radicals which contribute to aging. Retinol itself is sensitive to light and air, so packaging and formulation are important to maintain the effectiveness of this ingredient. For product recommendations, visit our Retinol category.

Rosacea

These clinically sensitive skin conditions 'over' respond to normal environmental and social factors. Atopic skin is extremely sensitive to any topical products, including normal cleansers and moisturizers, and often appears irritated and red. It is often difficult to identify a normal skin care regimen that does not irritate atopic skin, especially one that contains antiaging ingredients. Rosacea is an inflammatory condition that some researchers believe is caused or worsened by a microorganism on the skin, which makes the nose and surrounding areas appear very red and inflamed, and often shiny and broken out. Those prone to rosacea may experience a flare after drinking a glass a wine, going outside into cold weather, feeling embarrassed and flushed, drinking hot fluids or eating spicy foods. There are many different situations that cause a flare in rosacea, including using many skincare and cosmetic products. The Polyhydroxy Acid (PHA) Gluconolactone, is compatible with atopic dermatitis and rosacea, and provides the antiaging benefits expected from an AHA. And, in a clinical study of rosacea patients, adjunctive use of Gluconolactone-containing products was found to enhance the effects of the topical treatment azelaic Acid (Finacea®) resulting in smoother skin with less redness.

Rough

Dry skin conditions range from mildly dry with light flaking and skin tightness to extremely rough hyperkeratotic disorders. Most dry, chapped skin can be relieved through the use of a good moisturizer with AHAs and PHAs for gentle exfoliation, moisturization and skin conditioning. The more bothersome dry skin conditions on the face require an extra heavy emollient formulation in combination with skin normalizing / conditioning Alpha and Polyhydroxy Acids (AHAs and PHAs). The most severe forms of dry skin including ichthyosis and plaque psoriasis, generally require therapeutic products, and are best treated by a dermatologist. For product recommendations, visit our Sensitive/Dry and Dry/Scaly categories.

Saccharide Isomerate

Saccharide Isomerate strengthens skin barrier function. It is derived from plant based D-glucose and is made up of various sugars which are very similar in composition to the natural sugars found in the skin's own Natural Moisturizing Factor (NMF). When skin barrier function is compromised, dry, flakey, and even scaly skin can be the result.

Salicylic Acid

A topical anti-acne treatment that unclogs pores and clears acne blemishes, pimples blackheads and whiteheads.

Scaly

Dry skin conditions range from mildly dry with light flaking and skin tightness to extremely rough hyperkeratotic disorders. Most dry, chapped skin can be relieved through the use of a good moisturizer with AHAs and PHAs for gentle exfoliation, moisturization and skin conditioning. The more bothersome dry skin conditions on the face require an extra heavy emollient formulation in combination with skin normalizing / conditioning Alpha and Polyhydroxy Acids (AHAs and PHAs). The most severe forms of dry skin including ichthyosis and plaque psoriasis, generally require therapeutic products, and are best treated by a dermatologist.

Sensitive

'Sensitive' skin occurs from time to time in a majority of women, and each condition is as individual as the person experiencing it. While each person's condition is unique, the general condition is characterized by heightened sensory responses to chemical, environmental or social triggers. People with sensitive skin are more likely to experience stinging, itching, burning, dryness, redness and breakouts in response to their skin's particular trigger. Many people with sensitive skin experience mild stinging and burning from soaps and cleansers as well as Alpha Hydroxy Acids (AHAs) such as Glycolic or Lactic Acid. The Polyhydroxy Acid (PHA) gluconolactone provides the benefits of AHAs without the potential for stinging and burning even the most sensitive skin. If your skin sensitivity increases or becomes troublesome, you should visit a dermatologist since it could be a more serious skin condition requiring professional care. For product recommendations, visit our Sensitive/Dry category.

Skin Conditioning Agent

Ingredients used to provide special effects for the skin including enhancing the appearance of dry or damaged skin, reducing flaking and restoring suppleness. 1

Sodium Hyaluronate

Hyaluronic Acid, is a natural glycosaminoglycan (GAG) found in the skin's support matrix. GAGs bind up to 1000 times their weight in water. When applied topically, they attract water and moisturize.

Stressed

Skin is classified as 'stressed' when it negatively responds to various environmental and social factors by becoming dry, irritated, sensitive, unbalanced and / or blemished. Stressed skin needs the conditioning and protective actions of antioxidants and Polyhydroxy Acids. For product recommendations, visit our Oily/Acne-Prone and Hormonal/Menopausal categories.

Titanium Dioxide

An inorganic and physical sunscreen that absorbs, blocks and scatters UVA and UVB rays for broad-spectrum protection.

Turmeric

Turmeric is a plant from the ginger family. It is native to South Asia and is known for its medicinal qualities. It is used in the treatment of burns and other skin ailments. Turmeric helps the repair of free radicals and helps decrease the appearance of facial pigmentation by reducing the skin's melanin production. This ingredient is commonly used in skin brightening products to help those who suffer with uneven pigmentation. It is a powerful antioxidant that protects against environmental toxins.

Uneven Tone

Your skin has 'uneven tone' if you have areas of discoloration on your face, chest, shoulders or hands from years of sun exposure. Uneven skin tone is a visible sign of photoaging that may also occur after pregnancy or as a result of using oral contraceptives. Correct skin tone with topical skin brighteners and exfoliators and be sure to avoid the sun and use sunscreen daily. For product recommendations, visit our Texture & Tone category.

Vitamin A / Retinyl Acetate / Pro-Retinol

An antioxidant, that has been shown to enhance exfoliation, even the skin tone and diminish the appearance of fine lines and wrinkles. Ideal for use on acne prone skin.

Vitamin C / Ascorbic Acid

Vitamin C is required in the production of collagen, an essential protein that builds skin firmness and strength but decreases as you age, leading to wrinkles and laxity. Vitamin C can help reduce skin damage by scavenging free radicals and help keep skin protected from environmental damage. For a product with this ingredient, visit AF Vitamin C20 Serum Capsules.

Vitamin E / Tocopheryl Acetate

An antioxidant and skin conditioner that helps protect against the formation of free radicals and smoothes and softens skin.

Vitamin K

Helps to build skin strength and resiliency which helps to reduce the appearance of dark under eye circles.

Vitiligo

Vitiligo is a skin condition in which there is a loss of brown color (pigment) from areas of skin, resulting in irregular white patches that feel like normal skin. It most often affects the face, elbows and knees, and hands and feet. Vitiligo appears to occur when immune cells destroy the cells that produce brown pigment (melanocytes). This destruction is thought to be due to an autoimmune problem, but the cause is unknown. Vitiligo may appear at any age. The condition affects about 1 out of every 100 people in the United States. Treatments include topical drugs, phototherapy and/or concealing cosmetics to mask the condition. For product recommendations, visit our CoverBlend category.

Willow Herb Extract

A natural extract of Canadian Willow Herb, this calming agent was used by Native Americans to soothe skin and reduce redness caused by oxidative stress.

Wrinkled

Nearly all of the visible signs of aging are due to accumulated sun exposure. This condition, known as photoaging, causes the appearance of wrinkled, dull and lifeless skin on sun exposed areas of the body. The Alpha Hydroxy Acids, including Glycolic Acid and the Polyhydroxy Acids including Gluconolactone and Lactobionic Acid, along with daily sunscreen usage have been shown to help reverse some of the visible signs of photodamage. Repeated use makes the skin texture smooth with a reduced appearance of fine lines and wrinkles. AHAs also improve skin brightness and luminosity, helping to revitalize dull, lifeless skin. AHA products which are combination sunscreen plus moisturizers are recommended for daytime use. More intense corrective therapies are available from dermatologists and plastic surgeons as well as other skin care professionals. These include superficial peels, retinoids, lasers and dermabrasions. For product recommendations, visit our Aging Skin category.

Zinc Oxide

An inorganic and physical sunscreen that blocks or scatters UVA and UVB rays for broad-spectrum protection.
