The Safety and Efficacy of Salicylic Acid Chemical Peels in Darker Racial-ethnic Groups

BACKGROUND: There is a dearth of published data regarding chemical peels in darker racial-ethnic groups. OBJECTIVE: The purpose of the present investigation was to assess the clinical efficacy and safety of a new superficial salicylic acid peel in individuals of skin types V and VI. METHODS: Twenty-five patients were included in this pilot investigation. Nine had acne vulgaris, 5 had post-inflammatory hyperpigmentation, 6 had melasma, and 5 had rough, oily skin with enlarged pores. The patients were pre-treated for 2 weeks with hydroquinone 4% prior to undergoing a series of five salicylic acid chemical peels. The concentrations of salicylic acid were 20% and 30%. The peels were performed at 2 week intervals. RESULTS. Moderate to significant improvement was observed in 88% of the patients. Minimal to mild side effects occurred in 16%. CONCLUSION: The results of this study suggest that superficial salicylic acid peels are both safe and efficacious for treatment of acne vulgaris, oily skin, textural changes, melasma, and post-inflammatory hyperpigmentation in patients with skin types V and VI.
