Split face randomized, evaluator blinded study on the effect of multiple subcisions on rolling acne scars

Area of Science:

• Dermatology
• Medical Aesthetics

Background:

• Acne scarring significantly impacts patients' quality of life, affecting self-esteem and social acceptance.
• Current treatments like chemical peels and laser therapy have limitations in efficacy and duration.
• Subcision shows potential for treating rolling acne scars, but data on multiple treatments are scarce.

Purpose of the Study:

• To evaluate the efficacy of multiple subcision treatments in improving the appearance of rolling acne scars.
• To compare the outcomes of multiple subcision sessions against a control side with no treatment.

Main Methods:

• Five patients with bilateral rolling acne scars were enrolled.
• One side of the face received five sequential subcision treatments (4 weeks apart); the other side served as the control.
• Outcomes were assessed using patient and blinded rater evaluations, global scarring scores, and photographic analysis at multiple follow-up points.

Main Results:

• A greater decrease in global scarring scores was observed on the treated side compared to the control.
• Significant improvement in acne scar appearance was noted on the multiple subcision side by week 36.
• Fifty percent of patients reported higher satisfaction with the treated side versus the control side.

Conclusions:

• Multiple subcision treatments appear to be an effective method for improving the appearance of rolling acne scars.
• The findings suggest subcision is a viable treatment option, potentially offering better results with repeated application.
• Further research could explore optimal subcision protocols for various acne scar types.
