Salicylic acid and lactic acid are the most commonly used ingredients in Mary Kay Products. Depending on the type of cosmetic, a range of chemicals could comprise the products.
According to Patent US5520918, salicylic acid and lactic acid are skin-conditioning chemicals that can be applied topically to improve skin cell renewal rates with low irritation levels. Mary Kay cosmetics that use small amounts of a salicylic or lactic acid are usually combined with an anti-irritant or antioxidant substance.
Salicylic acid is a hydroxy acid that is used as primary ingredient in Mary Kay skin care products. The acid causes skin cells to shed more easily which opens clogged pores. Once the pores are open, the acid neutralizes bacteria within them and eventually allows for new skin cell growth. Outside the cosmetics industry, it is used to treat of acne, psoriasis, calluses, corns, seborrhoeic dermatitis and warts.
Lactic acid is balances and adjusts acidity levels in topical cosmetic treatments.
