Alpha Hydroxy Acids. Acids derived from fruit and milk sugars and used in certain creams and lotions. Alpha Hydroxy Acids are believed to reduce spots, wrinkles, and other signs of aging, sun-damaged skin.
Alpha Hydroxy Acid. Substance found in various fruits and milk that diminishes corneocyte cohesion that affects the thickness of the stratum corneum. Tartaric acid is found in grapes; malic acid in apples; lactic acid from soured milk; glycolic acid from sugar cane.
Alpha hydroxyl acids or AHAs are commonly found in many different concentrations in various products. The most common types are glycolic, lactic, malic, citric and tartaric acids which remove the topmost layer of the skin for a rejuvenated appearance.
Concentrated fruit acid that actively disintegrates the upper layer of the skin.
abbreviation for alpha hydroxyl acid which is a simple organic fruit acid found in nature or synthesized in the laboratory
alpha hydroxy acids aha's are derived from various plant sources or from milk and include glycolic acid, lactic acid, malic acid, citric acid and tartaric acid amongst others. They are effective chemical exfoliants, acting to breakdown dead skin cells.
A group of acids, often found in fruit, sour milk, sugar and others processed through bio-fermentation which, when applied to the skin, are believed to dissolve the glue-like lipids holding skin cells together in the stratum corneum; when their adhesive is dissolved, surface skin cells fall away, revealing younger-looking, fresher cells.
Alpha Hydroxy Acid increases exfoliation of the skin.
chemicals that simulate an abrasive by sloughing dead skin cells to reveal new, fresh cells underneath
All AHAs have a hydrating or exfoliating capacity. The action of AHAs is triggered by their quantity (more or less hydrating, exfoliating or even irritating when used in too high a concentration). The best known AHAs are: citric acid, malic acid, lactic acid and tartric acid. For purposes of illustration, in a content of up to 5%, lactic acid is hydrating. From 5 to 10% it is exfoliating. Above 10% it is an irritant. AHAs are acids found naturally in the human body or in some forms of fruit: grapes (tartric acid), apples (malic acid), lemons and oranges (citric acid). So they are often found under the label of fruit acids. In a cosmetic, they improve skin hydration, help boost cell renewal and have an anti-oily skin and anti-age effect.
ALPHA HYDROXY ACID. a group of acids that reduce sun induced fine wrinkles and pigment spots by removing the superficial layers of the skin and drawing moisture into the tissue, causing the skin to fill out. AMPOULES sealed, glass or plastic containers that keep solutions sterile until required for injection
Alpha Hydroxy Acids. Naturally occurring exfoliants derived from a group of weak acids in fruit, that encourages rapid cell renewal.
Used in anti-wrinkle products. Paul Penders uses glycolymer derived from sugar cane; it is a natural form of AHA with the smallest molecule to better penetrate the skin, and, considered the mildest of natural AHA's.
Alpha Hydroxy Acid. this organic acid taken from fruit acids, is used widely in anti-aging skin care products. It encourages moisture restoration, exfoliation and helps other ingredients to penetrate through the skin more effectively. Always use products containing AHAs in combination with sunscreen as they make your skin more susceptible to sun damage.
