A composition based on ascorbic acid and an appropriate method for treating aging or damaged skin by exposure to light are described. The composition includes water and ascorbic acid, at least a portion of which is pretreated by dissolution under conditions of relatively high temperatures and concentrations. The composition typically includes at least about 5% (weight to volume) of ascorbic acid and is preferably formulated so that its pH is above 3.5. In general, the composition also includes a non-toxic zinc salt, a tyrosine compound, and / or a cosmetically acceptable carrier. In addition, the composition may include an anti-inflammatory compound, such as an amino sugar and / or a sulfur-containing anti-inflammatory substance. The composition for external use may be in the form of serum, hydrophilic lotion, ointment, cream or gel. |
