Popis: Background: Treatments for striae distensae (SD) include both topical and semi-invasive methods, such as fractional radiofrequency microneedling (FRM) and carbon dioxide (FCO) laser therapy. However, no treatments have been completely satisfactory. Objectives: The safety and effectiveness of FRM alone, FCO laser alone, and their combination were evaluated for the treatment of SD. Methods: Each lesion was divided into 3 parts and each part was assigned to one of the 3 treatments (FCO, FRM, and combined FCO and FRM). Each lesion was evaluated by using a skin imaging analyzer and diagnostic ultrasound system, in addition to global photographic assessment by 3 dermatologists and a patient-scored visual analogue scale (VAS). Results: All 19 patients were female, with an average body mass index of 23.85 kg/㎡. The ultrasound result showed significantly greater overall skin thickness in the combined treatment group compared to the FCO group. The global assessment by dermatologists showed significant improvement in the combined treatment group compared to that in the other groups. The patient self-assessed VAS score in the combined treatment group showed significant improvement compared to that in the FRM group. However, skin imaging analysis showed significantly higher average melanin and hemoglobin levels in the combined treatment group compared to those in the other groups. Conclusion: Combined treatment using FRM and FCO showed better clinical outcomes and did not cause serious adverse reactions.
