Background: Striae distensae or stretch marks, although not a health risk, are of significant cosmetic concerns it affects the patient's psychological condition. Although many treatment modalities have been attempted with variable results, there is no standard treatment modality.
The aim of this work: was to compare the efficacy of a microneedling system (dermaroller) when used alone or in combination with 15-30% trichloroacetic acid (TCA) in the management of striae.
Conclusion: Both dermaroller and dermaroller + 15-30% TCA are effective treatment modalities for striae rubra. However, dermaroller + 15-30% TCA gives better results and dermaroller alone has fewer side effects.
