The Asian Problem of Frequent Laser Toning for Melasma.

In recent years, laser toning or laser facial to treat melasma has become increasingly popular in Asia. It is common to see patients undergoing lasers three times a week, or even daily. This is part of a growing trend and is sometimes recommended in the user manuals from laser manufacturers. In our study, we report on 23 Chinese patients who had lasers performed three times a week for two consecutive months, followed by rest. All 23 of them developed bilateral confetti-like hypopigmentation at the end of two months. During the four-month follow-up and rest, 10 patients were lost to follow-up. Of the remaining 13 patients, none of them had repigmentation. We conclude that frequent laser facials or laser toning at regular intervals may result in undesirable outcomes and thus should not be performed in regular intervals.
