Abstract：
:Striae gravidarum is a common dermatologic condition for females caused by multiple factors during pregnancy. It remains a therapeutic challenge especially in the striae alba (SA) stage, generating psychological and emotional distress to those affected. This study aims to compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and fractional microneedle radiofrequency (MRF) for treatment of SA striae gravidarum. Fourteen Chinese women with SA striae gravidarum were included in this study. Patient abdomens were randomly divided into NAFL and MRF treatment sides, treated three times at 6-week intervals. Treatment efficacy was evaluated by subjective (clinical assessments, patient satisfaction rating, adverse effects assessment) assessments and objective (skin melanin index measurement, histological study) assessments. Clinical assessment suggested MRF was more effective (P = 0.0143) for improving the appearance of SA striae gravidarum. Both NAFL and MRF demonstrated effective improvement (P = 0.0082 and P = 0.0158, respectively), with no significant difference according to patient satisfaction ratings and changes in melanin index (P = 0.5900). Both treatments induced limited adverse reactions, but MRF treatment caused significant pain compared with the more moderate NAFL treatment (P = 0.0003). MRF treatment increased neocollagen and elastic fibers more significantly than NAFL, based on histological assessments (P = 0.0298 and P = 0.0048, respectively). MRF treatment improved collagen regeneration in SA striae gravidarum more than NAFL but caused considerable pain during treatment. Corresponding treatment or therapeutic strategies should be applied according to clinical scenario.
