Efficacy and Safety of 30% Salicylic Acid and 10% Nicotinamide Combined Therapy in Melasma: A Randomized Placebo Controlled Study

Second Affiliated Hospital of Xi'an Jiaotong University·interventional·Posted Jul 14, 2025·Updated Jul 14, 2025

In Brief

A clinical study evaluating Nicotinamide(NAM)(10%), Supramolecular salicylic acid(SSA) (30%), and 2 other interventions for Melasma. Completed, enrolled 56 participants across 1 site.

Detailed Summary

This prospective, randomized, placebo-controlled study evaluated the synergistic effects of 30% salicylic acid (SA) chemical peels and topical 10% nicotinamide (NAM) in 56 patients with moderate-to-severe melasma. Participants were divided into four groups: placebo control, SA peels alone (every 2 weeks for 8 sessions), NAM cream alone (twice daily for 16 weeks), and combination therapy (SA+NAM). The investigators investigated the efficacy and safety of 30%SA chemical peeling combined with 10% NAM.

Interventions

Nicotinamide(NAM)(10%)other

The active niacinamide form of vitamin B3, NAM is routinely employed as a pigmentation-reducing agent in melasma treatment protocols

Supramolecular salicylic acid(SSA) (30%)other

Salicylic acid, a superficial chemical peel, has been widely used in treating melasma. Breakthroughs in supramolecular design have addressed its irritancy profile through engineered SA complexes with improved water dispersibility
