Abstract
INTRODUCTION: Fractional resurfacing with an Erbium:yttrium-aluminum-garnet (Er:YAG) 2940 nm laser is an increasingly popular option for the treatment of the signs of facial photoaging, which include wrinkles as well as pigmentation issues and unwanted textural changes. Fractional treatment has produced favorable clinical responses, but with less complications and shorter recovery times than traditional laser resurfacing. This study was conducted to evaluate a fractionated Er:YAG treatment regimen of 1-2 higher fluence sessions with a multiple-pass technique. MATERIALS AND METHODS: Eight subjects with moderate to severely photodamaged facial skin received one to two full-face laser treatments. Multiple-pass (MP) treatment results were evaluated in terms of procedure time, discomfort, social downtime and effectiveness. A photographic evaluation, subject improvement assessments and a subject satisfaction assessment were performed. RESULTS: An investigator's photographic review showed a 26-75% improvement in the signs of overall photoaging. Subjects treated with the MP technique exhibited a relatively short 3-4 day downtime and ratings of mostly moderate discomfort with the use of topical anesthetic cream only. Subjects treated with higher fluences demonstrated the highest average improvement in specific features of photoaging. Two laser treatments resulted in substantially higher improvement scores than those received just one laser treatment.
