Efficacy Of Micro-Needling On Post Acne Scars

Area of Science:

• Dermatology
• Aesthetic Medicine
• Minimally Invasive Procedures

Background:

• Acne affects a vast majority of adolescents globally, often leading to disfigurement and psychological distress from scarring.
• Various treatments exist for acne scars, including lasers, dermabrasion, and chemical peels, with variable efficacy.
• Micro-needling, a collagen induction therapy, shows promise for treating acne scars.

Purpose of the Study:

• To evaluate the efficacy and safety of micro-needling for treating post-acne scars.
• To assess the aesthetic improvement achieved through micro-needling sessions.
• To determine the effectiveness of micro-needling in reducing scar severity.

Main Methods:

• A cross-sectional study involving 50 patients (35 female, 15 male) with post-acne scarring.
• Four sessions of micro-needling were administered under local anesthesia, spaced three weeks apart over two months.
• Qualitative assessments and photographic analysis using the Goodman and Baron scale were performed for pre- and post-treatment comparison.

Main Results:

• Significant improvement was observed across scar grades post-treatment.
• Grade 4 scars showed improvement by 1-2 grades in all patients.
• Grade 3 scars improved by 1-2 grades, and Grade 2 scars downgraded to Grade 1.
• Statistical analysis confirmed a significant improvement in scar grading (X²=30.010, p=0.000).

Conclusions:

• Micro-needling is a safe and effective treatment for improving the aesthetic appearance of post-acne scars.
• The procedure stimulates collagen production, leading to noticeable scar reduction.
• It offers a viable therapeutic option for individuals seeking to address acne scarring.
