Abstract

Striae distensae (SD) are linear scar tissue in the dermis that arises from stretching the skin. There are two types of SD, striae rubrae and striae albae (SA) which is marked with a line hypopigmentation that cause a psychological problem, especially in the high skin type. The standard therapy is a 0.1% tretinoin cream, but it takes a long time to reach the collagen so it needs invasive measures to reach these targets. This study was comparing 0.1% tretinoin cream with combination therapy of fractional microneedle radiofrequency (FMR) and fractional CO2 laser for SA. The number of subjects in this study was 11 patients each group with Fitzpatrick skin types IV or V. Biopsy was taken before and after therapy. The clinical changes in SA lesions in this study were represented by measurements of the length and width. The percentage of collagen area is the amount of collagen fibers with Masson’s trichrome staining. The clinical changes of lesion in the combination therapy decreased. The percentage change in collagen area in the combination therapy group had a higher increase. The side effect experienced by all combination group subjects was postinflammatory hyperpigmentation, two subjects in 0.1% tretinoin cream group experienced irritation.
