    Studysummary This review indicates that microneedle bipolar RF and fractional bipolar RF treatments offer significant improvement in acne scarring, with optimal results observed about three months after treatment. Our plain-language summary of this paper — not a Tressless recommendation.
    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.
