In cosmetics, Malic Acid is categorized as an alpha-hydroxy organic acid. This is a term that describes fruit acids which are included in many beauty treatments, cleansers, creams and lotions. They are used mainly because of their exfoliating ability and because they act as mild chemical face peels revealing firmer, younger skin. Malic Acid is also able to increase cellular action and energy. The skin appears fresher and the depth of wrinkles are less.
AHA facial skin care peels are effective in helping oily skin and acne skin as well as alleviating dry, rough skin. As skin ages and due to sun exposure, there is a slowing down in the rate at which older cells are replaced by newer cells. Due to the adhering of the older cells to the surface of the skin, the skin appears aged. AHA’s loosen the substances that hold the skin cells on the surface of the skin together. This allows the shedding of the sun damaged, old surface of the skin to shed itself and also encourages the growth of the cells underneath the skin. Skin has a healthier and even texture and color and can help to erase age spots.
AHA’s is only able to penetrate to a depth of .06 mm in the skin, through the stratum granulosum and papillary dermis but the more repetitive the peel the more profound the effect is on the skin. With long-term use the deeper layers of the skin may become affected by the AHA and the collagen and elastin in these layers may be encouraged to regenerate themselves and fine lines may disappear.
Malic Acid is used to adjust the pH of cosmetic formulations.
