Randomized Controlled Trial Comparative Study
Comparative study on efficacy and safety of 1550 nm Er:Glass fractional laser and fractional radiofrequency microneedle device for facial atrophic acne scar.
The 1550 nm Er:Glass fractional laser is widely used for the treatment of atrophic acne scar. A novel fractional radiofrequency microneedle device has recently emerged as an alternative for treating acne scars. ⋯ Atrophic acne scars improved in both groups without significant side effects. Additionally, the fractional laser was a more effective treatment option for acne scars, but the fractional radiofrequency microneedle device offered good adherence and short downtime.
