Melasma is a common problem amenable to different peeling regimes. We evaluated the effects of 4 regimes that included glycolic acid alone and in combination with trichloroacetic acid and liquid nitrogen with 15 patients in each schedule. The peeling was done every 2 weeks for 3 months. The response rate with each of the treatment schedules was good (p<0.01), but there was no difference in improvement with different treatments (p<0.05). Occasional minor side effects were noticed that responded to simple measures and did not warrant discontinuation of theray.
