This is a multi-purpose cream that can be used for a number of conditions including sun damaged or dry skin. Alpha Hydroxy Acid (Lactic Acid) reduces cell adhesion in the top layer of the skin. This action promotes exfoliation of the outermost layer of the skin which results in a smother texture following regular use of topical AHA cream. This relatively low concentration of lactic acid (10%)  lends itself to daily use as a part of a skin care management program for such conditions as acne, sun damage, and wrinkling. 
Precaution: Consult with your Dermatologist or a Skin Care Expert if melasma is present. 
Because of its safety, Alpha Hydroxy Acid (Lactic) at concentrations at or below 10% can be used daily by most people except those with very sensitive skin.
