Zusammenfassung: | Background and Objective
A minimally invasive fractional radiofrequency microneedle (FRM) device has been used in skin rejuvenation and acne scars, and a recent pilot study demonstrated the positive therapeutic effect on acne. We evaluated the efficacy of FRM device for acne vulgaris in Asians and conducted objective measurement to assess its effect on sebum production.
Patients and Methods
Twenty Korean patients with acne vulgaris received a single full‐face FRM treatment. Outcome assessments included standardized photography, physician's global assessment, patient's satisfaction scores, acne lesion count, and objective measurements of casual sebum level (CSL) and sebum excretion rate (SER). They were evaluated at baseline and 2, 4, 8 weeks after the treatment.
Results
After a single FRM treatment, the CSL and the SER showed 30–60% and 70–80% reduction, respectively, at week 2 (P |
