Malic acid, like citric acid and tartaric acid is an acid naturally present in the human body and/or certain fruits: grapes (tartaric acid), apples (malic acid), lemon and orange (citric acid).
These acids are known as AHA (alpha hydroxy acids). Malic acid, tartaric acid and citric acid are all known as fruit acids.
Malic acid is found naturally in apples, pears and grape juice.
Malic acid and malic acid salts are effective organic preservatives, effective against microorganisms.
Tartaric acid is present in many plants and is the main acid in wine.
In cosmetics, malic acid and other fruit acids will improve the skin's moisture level and help renew cells. They have an anti-oily and anti-aging effect on the skin.
The extent to which AHA has a moisturising or an exfoliate, even irritant effect at high concentrations, depends on the amount of AHA introduced into a cosmetic preparation.
