Abstract

Abstract: Objective To elucidate the efficacy and safety of long-pulsed 1064nm Nd:YAG laser in the treatment of moderate to severe acne complicated with post-acne erythema. Methods A total of 20 cases of moderate to severe acne complicated with post-acne erythema were recruited, who were treated with long-pulsed 1 064 nm Nd:YAG laser. The laser parameters were: 25~30 J/cm², 3.0 Hz, 20~40 ms pulse duration, 6.0 mm spot size. All patients were treated once a week for 8 weeks. Pictures of acne lesions were taken and the numbers were recorded before and after treatment. Results Of all 20 cases, 17 were cured, and 3 were improved. The total effective rate was 100%. The number of acne lesions was significantly reduced (P<0.05). Meanwhile, the texture of the skin was improved, and more than 90% patients were satisfied. The treatment effect of early inflammatory lesions was better than that of acne erythema (P<0.05). The side effect was transient erythema after treatment. Conclusion s Long-pulsed 1 064 nm Nd:YAG laser is safe and effective in the treatment of moderate to severe acne with acne erythema. It is a new therapeutic approach for acne and persistent post-acne erythema.
