COMPARATIVE STUDY
JOURNAL ARTICLE
Microneedle fractional radiofrequency treatment of facial photoageing as assessed in a split-face model.
Clinical and Experimental Dermatology 2019 June
BACKGROUND: A new therapeutic device passes radiofrequency energy through microneedles to targeted tissue. Three-dimensional photography may be useful for evaluating the clinical efficacy of microneedle fractional radiofrequency (MFR) used on the appearance of rhytids and to improve facial laxity.
AIM: To evaluate the efficacy and safety of MFR in the treatment of facial photoageing.
METHODS: In total, participants with facial photoageing were enrolled in the study. All volunteers were randomized to receive split-face treatments with MFR 2 months apart. The participants self-evaluated at baseline, Days 1-7, and Months 1 and 3 after the final treatment. Objective evaluation was provided by a three-dimensional in vivo imaging system. In addition, skin melanin index, erythema index, immediate reactions, healing times and other adverse effects were evaluated.
RESULTS: Compared with the untreated side, the treated side of most participants improved, based on clinical assessments at the 1- and 3-month follow-up visits after treatment. Both objective and participative assessments were satisfactory. The participants demonstrated a decrease of roughness parameter (Sa) value at each follow-up visit. Compared with pretreatment value, Sa decreased significantly at Months 1 and 3 on the treated side (P < 0.05). Minimal and reversible adverse effects and rapid healing were recorded.
CONCLUSIONS: MFR appears to be an excellent treatment for photodamaged facial skin in Chinese patients.
