The study seeks to resolve uncertainty about the long-term efficacy of fractional resurfacing devices. While pulsed carbon dioxyde laser resurfacing is considered a highly effective treatment, fractionated resurfacing is a newer modality and its long-term efficacy has yet to be assessed. The study reports the long-term outcomes of subjects previously treated with fractional carbon dioxyde resurfacing for photodamaged skin and acne scars.
The study finds that patients retained 74% of their original improvement long-term. The study concludes that fractional carbon dioxyde laser resurfacing does have long-term efficacy and persistence of improvement of acne scarring and photodamage compared to baseline. However, additional treatments may be necessary to enhance long-term results.
