Clinical improvement of striae distensae in Korean patients using a combination of fractionated microneedle radiofrequency and fractional carbon dioxide laser.
Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery [et Al.] 2013 October
BACKGROUND: Striae distensae are dermal scars with flattening and atrophy of the epidermis.
OBJECTIVE: To evaluate the efficacy and safety of combination therapy with fractionated microneedle radiofrequency (RF) and fractional carbon dioxide (CO2) laser in the treatment of striae distensae.
MATERIALS AND METHODS: Thirty patients (30 female; mean age 33, range 21-51, Fitzpatrick skin type IV) with moderate to severe striae distensae were enrolled in this study. Patients were divided into three groups: fractional CO2 laser only (n = 10), microneedle RF only (n = 10), and combination (n = 10).
RESULTS: Improvement was evaluated using a visual analogue scale (range 1-4). Mean clinical improvement score of the dermatologist was 2.2 in the fractional CO2 laser-treated group, 1.8 in the microneedle RF-treated group, and 3.4 in the combination group. Through skin biopsy, we observed thickened epidermis and a clear increase in the number of collagen fibers in the microneedle RF- and fractional CO2 combination-treated sites. Consistent with these results, greater expression of transforming growth factor-β1 and stratifin was observed in treated sites.
CONCLUSION: Combination therapy of fractionated microneedle RF and fractional CO2 laser is a safe treatment protocol with a positive therapeutic effect on striae distensae.
