Pyruvic acid acts at the level of the epidermis and dermis. It Loosens the connection between the corneocytes and prevents nubs of the stratum corneum. Exfoliation proceeds without the drying effect, as pyruvic acid is hydrolyzed into lactic and alpha-hydroxy acid with moisturizing properties, leaving film on the skin to protect it against dehydration.
Due to the keratolytic, sebum-regulating and antimicrobial action, it is particularly indicated for treating acne of different type. It stimulates the synthesis of collagen, elastin and glycoproteins in a higher degree than glycolic acid and comparable to TCA but without the drawbacks of the TCA, causing only mild redness after the treatment.
Indications: average depth wrinkes, ignitable inflammatory acne, acne scars.
