- A recent L’oréal research study compared the efficacy of glycolic acid (GA) to capryloyl salicylic acid (LHA)in treating wrinkles hyperpigmentation, inside cosmeceuticals reports.

The study, published in the Journal of Cosmetic Dermatology randomized 50 female volunteers between the ages of 35 and 60, with mild-to-moderate facial hyperpigmentation and wrinkles. LHA or GA peel was applied to one side of the face, with increasing peel concentrations for 12 weeks at biweekly intervals.

Of the 44 volunteers, 41 percent of those treated with LHA showed a significant improvement of wrinkles, while 30 percent of GA-treated volunteers showed improvement. Also, 46 percent of LHA volunteers showed improvement in hyperpigmentation, compared with 34 percent of patients treated with GA.
