Evidence: In a double-blind, vehicle-controlled trial of 30 people with two or more solar lentigines, a serum with 10% L-ascorbic acid and 2% phytic acid lowered the pigmentation index of the treated lesions over three months while the vehicle-treated lesions stayed stable (P <= 0.003 from month 1 to month 4). Six adverse events, mostly halo depigmentation, were judged possibly related to the product.
