This study showed that application of 82% lactic acid peel decreased the MASI score which was statistically significant. Melasma severity scale score also showed significant difference in grade 2 patients. Patient and physician analogue scales also showed the improvement by lactic acid treatment. Besides these no side effects were noted in our study except the burning sensation. Therefore we conclude that 82% lactic acid peel is well tolerated and safe agent that can be used for the treatment of melasma but more studies on Indian patients using larger sample sizes are needed to validate our results.
