Abstract
The 1064-nm Nd:YAG laser in Q-switched and micropulsed modes has been used in rejuvenation, pore reduction, skin texture improvement, and wrinkle reduction. The aim of this study is to evaluate the combination of 1064-nm Nd:YAG laser in micropulsed and Q-switched modes in the same session for global facial treatment. Thirty female patients underwent six treatment sessions every two weeks. Three blinded dermatologists evaluated the results through clinical photographs and Visia® or Focco® images obtained before and 30 days after the last treatment session. The parameters of interest were solar melanosis, telangiectasias, wrinkles, dilated pores, melasma and skin texture. Three patients had face biopsies before and 30 days after the end of treatment. Most patients showed improvement in all evaluated parameters, except for two patients who had worsening of melasma. An increase in collagen was observed in two of the three histological examinations performed after treatment. The combination of laser modes studied herein offers a safe treatment that can improve wrinkles, skin texture, and laxity with minimal downtime.
