Summary
This completed study tested a brightening treatment (a type of chemical peel) combined with a retinol serum and post-procedure cream on 11 healthy women aged 20 to 65 with moderate facial pigmentation from sun exposure or blemishes. Participants received four treatment sessions two weeks apart and were followed for 12 weeks. The goal was to see if the treatment safely improved skin pigmentation and texture.
