Ablative fractional lasers (CO₂ and Er:YAG): A randomized controlled double‐blind split‐face trial of the treatment of peri‐orbital rhytides

Abstract

According to the present study, a single ablative fractional treatment session has an appreciable yet limited effect on peri-orbital rhytides. When fractional CO(2) and Er:YAG lasers are used in such a manner that there are comparable post-operative healing periods, comparable cosmetic improvement occurs. Multiple sessions may be required for full effect, which cancels out the proposed advantage of fractional methods, that is, fewer side effects and less down time.
