Fruit acids: the concept and varieties
Fruit acids are alpha hydroxyacids (abbreviated as ANA), substances of natural origin. There are different types of fruit acids: lactic, wine, malic, glycolic, citric, salicylic and others. Fruit acids are prepared from berries, fruits, milk and sugar.
For example, lactic acid is found in fermented milk products, blueberries, grapes, apples, tomato juice. And citric acid is present in almost all citrus species.
Most fruits are rich in malic acid. Creams, which include it, perfectly moisturize the skin. It is used in medicine, cosmetology and cooking.
Useful properties of fruit acids
Fruit acids are excellent excipients, stimulating fibroblasts of the skin and affecting its regeneration. They work with skin at three levels at once — cellular, molecular and tissue.
Acids have anti-inflammatory and antioxidant effects on the skin, smooth small (shallow) wrinkles, moisturize the skin. They exfoliate dead cells well from the surface of the skin, giving it a fresh look and improving complexion.
Each of the fruit acids has its beneficial properties. Lactic acid has a magnificent moisturizing and exfoliating effect.
Glycolic acid has the smallest molecule, so easily penetrates through the epidermal barrier and takes part in the production of collagen types one and three. It is the main component of modern ANA peels, often used to treat skin hyperpigmentation.
Almond acid is obtained from the fruits of bitter almonds. It is a natural antibiotic, so it is used in professional peels and home care products for problem skin.
Fruit acids are found in cosmetics in various concentrations. When a high concentration of AHA is used, the cosmetic procedure should be performed by a specialist, but not more often than once every three to six weeks.
Tartaric or tartaric acid has a lightening and moisturizing effect when exposed to the skin.
In addition to its bactericidal and antioxidant properties, citric acid bleaches the skin well.
In the general composition, fruit acids enhance each other’s effectiveness. But remember that ANA is quite strong substances, so before using cosmetics with fruit acids in the composition, it is necessary to make a test for allergic reactions.
