Multiple fractional erbium: yttrium–aluminum–garnet laser sessions for upper facial rejuvenation: clinical and histological implications and expectations

Abstract

Multiple sessions are effective in rejuvenation of the aging face with high safety, short downtime, and no adverse effects. They stimulated formation of new collagen (type I, III, and VII) up to 6 months after treatment with better improvement in skin texture and fine wrinkles. The variable number of fractional Er:YAG laser sessions (3-5) showed no significant difference as regards efficacy.
