Abstract

Objective: To evaluate the clinical efficacy of fractional laser treatment combined with bipolar radiofrequency for improving atrophic facial acne scars.

Methods: The clinical data of patients with atrophic facial acne scars treated in the Dermatology Department of The People's Hospital of Chongqing Liangping District from October 2022 to 2023 were retrospectively analyzed. The patients were divided into two groups based on treatment methods: the single intervention group (Group A, n=25) and the combined intervention group (Group B, n=25). Group A received bipolar radiofrequency therapy only, with a treatment cycle of 4 weeks and 4 cycles per treatment course. Group B received combination treatment, starting with carbon dioxide (CO₂) laser therapy for 2 weeks, followed by bipolar radiofrequency therapy for 2 weeks, alternating between the two modalities for 4 cycles per treatment course. Six months post-treatment, three doctors performed a blinded evaluation of facial photos from both groups using the Echelle d'evaluation clinique des cicatrices d'acne (ECCA) to assess clinical efficacy. Outcome measures included changes in scar texture and facial atrophy, adverse reactions, and patient satisfaction.

Results: The facial acne scars in both groups were classified as type III-IV before surgery. Post-treatment follow-up showed significant improvements in scar texture and atrophy in both groups. Group B demonstrated superior treatment outcomes compared to Group A. Specifically, the incidence of edema and pigmentation was lower in group B with a shorter duration of edema, faster wound healing, and reduced rest time compared to group A. Patient satisfaction was also higher in group B.

Conclusion: Fractional laser treatment combined with bipolar radiofrequency therapy is an effective combination for patients with atrophic acne scars, offering minimal side effects and enhanced patient satisfaction.
