Description

Acne scars are common and can have a lasting impact on self-esteem, social relationships, and quality of life. Several treatment options exist, but many patients continue to seek better results. Microneedling is a minimally invasive technique that uses small needles to stimulate skin repair. Fractional lasers, such as Erbium:Glass (1540-1550 nm) and Thulium (1927 nm), deliver energy into the skin to promote remodeling of deeper and more superficial layers. The combination of these two fractional lasers may provide a more comprehensive treatment approach for acne scars.

This clinical trial will directly compare these two options: microneedling versus the combined use of fractional Erbium:Glass and Thulium lasers. A total of 84 adults between 18 and 30 years old with atrophic acne scars will take part. Participants will be randomly chosen by a draw (like a lottery) to receive one of the two groups. Both groups will receive three treatment sessions, with four weeks between each session.

The main goal is to determine which treatment leads to greater improvement in acne scars. Improvement will be measured by independent evaluators who will compare standardized before-and-after photographs using a grading scale. Participants will also report their own satisfaction with the results and how well they tolerated the treatments. Follow-up assessments will occur up to 90 days after the last session.
