BACKGROUND: Ablative fractional erbium-doped yttrium aluminum garnet (Er:YAG) laser and microneedling have been popularized in recent years and their effectiveness and side effects individually reported. No previous study, however, has directly compared the efficacy and safety between the 2 different treatments.
OBJECTIVE: To compare the efficacy and safety of the ablative fractional Er:YAG laser and microneedling for the treatment of atrophic acne scars.
MATERIALS AND METHODS: Thirty patients with atrophic acne scars were randomly treated in a split-face manner with a fractional Er:YAG laser on one side and microneedling on the other side. All patients received 5 treatments with a 1-month interval. Objective and subjective assessments were obtained at baseline and at 3 months after the final treatment.
RESULTS: At the 3-month follow-up, both treatment modalities induced noticeable clinical and histological improvement, with significantly better results in fractional Er:YAG laser versus microneedling (70% vs 30%), respectively (p < .001). Fractional Er:YAG laser sides had significantly lower pain scores. Total downtime was significantly shorter in microneedling sides.
CONCLUSION: Both treatment modalities are effective and safe in the treatment of atrophic acne scars, with significantly higher scar response to the fractional Er:YAG laser treatment.
