Comparison of insulated and non-insulated radiofrequency microneedling for the treatment of Striae Distensae
Abstract:
Striae distensae (SD), also known as stretch marks, are dermal scars that could induce psychological problems. Despite numerous studies, no conventional therapies have been developed. Fractional radiofrequency microneedling (RFMN) is a novel treatment for atrophic scars and wrinkles. Energy fractions thermally damage deep dermal collagen near unaffected parts. The treated areas recover, remodel, and produce new collagen. Fractional RF delivery depends on microneedle insulation and frequency. The main objective of this study is to compare the efficacy of non-insulated and insulated fractional RFMN for the treatment of SD at 1 and 2 MHz frequencies. Eighteen subjects with striae alba on their thighs, abdomens, or buttocks were enrolled. Each patient was divided into four treatment zones with similar shapes and sizes. Each area was randomly treated with 1 MHz insulated, 2 MHz insulated, 1 MHz non-insulated, and 2 MHz non-insulated RFMN. Clinical outcome was assessed after 4 weeks by comparing pre- and post-treatment measurements of lesion depression volume, depth, and width (using Antera 3D™). At week 4 after treatment, the results showed all techniques were effective. The depression volume and the depth of SD significantly decreased from the baseline in all groups. The 2 MHz insulated and 1 MHz non-insulated RFMN groups performed slightly better, but the difference was not statistically significant. (p = 0.90). In conclusion, both insulated and non-insulated RFMN at 1 MHz and 2 MHz are effective, safe and have minimal adverse effects for treating SD.
