TLDR Nonablative radiofrequency treatments, especially microneedle and fractional types, can improve acne scars by 25%–75% after 3-4 sessions, with full results in 3 months and some side effects.
The document reviews the use of nonablative radiofrequency (RF) treatments for acne scars, a condition that can lead to psychological issues. It compares various treatments and highlights microneedle bipolar RF and fractional bipolar RF as the most effective RF modalities, with patients seeing a 25%–75% improvement in scar appearance after three to four sessions. Optimal results are seen approximately 3 months post-treatment. Side effects include pain, redness, and scabbing. The review suggests that further research is needed to tailor RF treatments to specific types of scars for better outcomes.
