SUMMARY
Abstract
This study evaluated the long-term histological effects of fractional radiofrequency (FRF) microneedling (Fractora, InMode) on acne scars. Patients underwent four treatments, and biopsies were taken before, after treatment, and 3.5 years post-treatment. Histological analysis demonstrated significant dermal remodeling, including regeneration of elastic fibers, collagen deposition, and scar tissue reduction. Patient samples revealed scar depth reduction of up to 80%, with lasting improvements in skin architecture and clinical appearance.
Conclusion
Fractional RF microneedling provides safe, long-term correction of acne scars through deep dermal remodeling and regeneration of collagen and elastin. Results sustained 3.5 years post-treatment confirm its durable efficacy. The study establishes fractional RF as a leading modality for acne scar treatment with superior long-term outcomes compared to conventional resurfacing methods.
