|
Background and Objectives: Noninvasive radio frequency (RF) devices have been used in treatment of facial wrinkles. Fractional microneedle RF system was studied to assess the clinical efficacy and safety in treatment of facial wrinkles.
Materials and Methods: A total of 204 patients (80 male, 124 female; mean age 47.3, range 26-68; Fitzpatrick skin type III to type IV) with facial wrinkle were treated with 1-3 sessions of fractional microneedle RF system at an average interval of 4 weeks at three study centers in Korea.
Results: Of the 204 patients, 54 had grade 4 clinical improvement, 86 had grade 3 improvement, 50 had grade 2 improvement, and 14 had grade 1 improve-ment. Mild post-inflammatory hyperpigmentation was found in only two of the 204 patients, which spontaneously resolved within one month.
Conclusion: Fractional microneedle RF system was effective and safe in the treatment of facial wrinkles.
