Abstract

There is a few study in Vietnam on the effect of picosecond laser ND YAG 532 nm treated on freckle. So that we conducted the study with the aim: The evaluate the effect of freckle treatment by picosecond laser ND YAG 532nm. The study was conducted on 32 patients diagnosed freckle in Hanoi dermatology hospital from July 2021 to July 2022 treated by using picosecond laser (QuanTa-Italia). The effect was evaluated before and after treatment by using Von-Luschan, lesion area, Brown sport indexes. Von-Luschan index was significantly reduced with p<0.001; with 34.4% very good and 56.2% good. Lesion area was significantly reduced p<0.001 (585.57 ±189.24 mm2 and 173.49 ± 86.67 mm2) with 62.5% very good and 37.5% good. Brown sport index was significantly improved with p <0.001 (50.0% very good and 43.8% good). Study shown that picosecond laser ND YAG 532 nm was effectiveness on freckle treatment but we should conduct study with larger sample to confirm the effectiveness and safety of this method.
