Pyruvic acid is alpha-keto acid. It is converted physiologically to lactic acid. It induces both epidermal and dermal effects by diminishing the cohesion of epidermal corneocytes, and increasing production of collagen, elastic fibres and glycoproteins.
Pyruvic acid helps patients with photoaging leading to a smoother texture, less evident fine wrinkles and an important lightening of hyperpigmentations (freckles and lentigines). It also causes improvement of acne lesions and important decrease of seborrhoea.
Pyruvic acid causes very mild erythema, mild desquamation, and has a short post-operative period.
