  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.

Condition Intervention Phase
Melasma Drug: 20-30% Salicylic Acid peels to the right side of the face Drug: 20-30% Salicylic Acid peels to the left side of the face Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: The Efficacy of Salicylic Acid Peels Combined With 4% Hydroquinone Cream Versus 4% Hydroquinone Cream Alone in the Treatment of Hispanic Women With Moderate to Severe Melasma

Primary Outcome Measures:
  • Number of Participants Showing Improvement of Melasma Based on Mexameter Readings [ Time Frame: 14 weeks ]
    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 ]
