Alpha Hydroxy acids suitably applied, break the bonds between the layers of superficial dead skin, enabling the sloughing of old cells at a greater rate than is normal. This results in an overall improvement in skin appearance by revealing the newer skin underneath. Thus, this is a pure, Lactic Acid AHA treatment for the face. Suitable for all skin types, has moisturising effect. Contains very pure high concentration of Lactic acid pH buffered with a minimum of extra ingredients to prevent irritation. Safe to use for long term if required.
