COMPARATIVE STUDY
JOURNAL ARTICLE
RANDOMIZED CONTROLLED TRIAL
Comparison of fractional erbium-doped yttrium aluminum garnet and carbon dioxide lasers in resurfacing of atrophic acne scars in Asians.
Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery [et Al.] 2013 January
BACKGROUND: The efficacy of fractional erbium-doped yttrium aluminum garnet (Er:YAG) and carbon dioxide (CO(2) ) lasers are well substantiated.
OBJECTIVE: To compare the efficacy and safety of these two laser systems for treatment of atrophic scars in dark-skinned patients.
MATERIALS AND METHODS: Twenty-four subjects with acne scars were randomly treated with a fractional Er:YAG laser on one side and a fractional CO(2) laser on the other side. All subjects received two treatments with a 2-month interval. Objective and subjective assessments were obtained at baseline and 1, 3, and 6 months after the final treatment.
RESULTS: At the 6 month follow up, 55% and 65% of Er: YAG and CO(2) laser sites, respectively, were graded as having more than 50% improvement of scars. Improvement progressed significantly from 1- to 6-month follow-up (p < .001). There was no significant difference in clinical improvement between the two systems at 1- (p = .90), 3- (p = .54), and 6-month (p = .87) follow-up. Reduction in scar volume corresponded to clinical evaluation.
CONCLUSIONS: Fractional Er:YAG and CO(2) lasers provided comparable outcomes of scar treatment, but fractional CO(2) laser was associated with greater treatment discomfort.
