A Single Center, Prospective Randomized Controlled Clinical Trial on the Efficacy and Safety of Microneedle Radiofrequency Combined With Oral Isotretinoin in Moderate to Severe Acne Vulgaris
This study plans to select 100 AV patients and randomly divide them into two groups in a 1:1 ratio: the experimental group will be treated with MRF combined with oral isotretinoic acid for 8 consecutive weeks, with a total of 3 MRF treatments at weeks 1, 4, and 8. The control group received oral administration of isotretinoic acid alone for 8 weeks. The main observation indicators are the percentage of effective skin injury clearance achieved by subjects at week 20, as well as the change in ECCA acne scar score compared to baseline at week 20. I hope this study can clarify that the combination therapy of the two can achieve the effects of improving efficacy, shortening treatment course, reducing recurrence, not increasing adverse reactions, and reducing the risk of scar formation.
