Salicylic Acid Peels Combined With 4% Hydroquinone in the Treatment of Moderate to Severe Melasma in Hispanic Women - Full Text View

Purpose

This study will enroll 20 adult Hispanic women. Participants will apply 4% hydroquinone cream twice daily to affected areas on the face for 14 weeks and half the face will be peeled with 20-30% salicylic acid every two weeks for a total of 4 peels. The first two peels will be 20% salicylic acid and the second two peels will be with 30% salicylic acid. The purpose of the study will be to evaluate the safety and efficacy of salicylic acid combined with 4% hydroquinone versus 4% hydroquinone alone.

Primary Outcome Measures:

Number of Participants Showing Improvement of Melasma Based on Mexameter Readings [ Time Frame: 14 weeks ] [ Designated as safety issue: No ]
The degree of participants pigmentation was measured from the affected and unaffected skin on both sides of the face using a narrowband reflectance spectrophotometer.

Secondary Outcome Measures:

Improvement of Melasma Based on MASI Scores, Melasma Severity Assessment, and Physician and Patient Global Improvement Compared With the Opposite Side. [ Time Frame: 14 weeks ] [ Designated as safety issue: Yes ]
