LACTIC ACID: Is found in the hydro-lipid film of the skin, where it helps stabilize of the protective acid mantle, binds moisture and controls the keratinization of the epidermis. Since lactic acid is pH-regulating, it can inhibit the growth of foreign microorganisms on the skin.
Lactic acid is generally an excellent skin moisturizer and moisture binder. Higher concentration of lactic acid are used as gentle skin surface peels and in cleaning and care products for blemished and acne-prone skin by reducing the keratinized cells and extracting comedones.
CITRIC ACID: Citric acid occurs naturally in citrus fruits and belongs to the group fruit acids. Citric acid acts especially astringent and toning, supporting the healing process. The antiseptic effect is particularly effective against blemished skin. Due to the relative weak acidic properties, citric acid is also effective against fungal infestation.
GLYCOLIC ACID: Glycolic acid is an ingredient found naturally in sugar cane juice from the sugar cane plant and belongs to the group of alpha-hydroxy acids. Glycolic acid provides multiple benefits in cosmetic products: It dissolves keratinized skin cells by softening the adhesive cell structures in the horny layer. Skin regeneration is stimulated and lines and wrinkles can be reduced. The skin texture is refined, with a clearer complexion, increased moisture retention and elasticity.
