Subcision, chemical peels, and platelet‐rich plasma: Combination approaches for the treatment of striae distensae

Abstract

Striae distensae (SD) are disfiguring skin condition causing cosmetic troubles and psychological distress. The aim was to compare the efficacy and safety of platelet‐rich plasma (PRP) versus its combination with subcision or medium‐depth peeling (glycolic acid 70% followed by trichloroacetic acid [TCA] 35%) for SD treatment. Seventy‐five female patients with SD were divided into three equal groups with the contralateral side in each patients represented the control group. Group A treated with PRP, group B received PRP + subcision while group C received PRP + combined peeling (GA 70% + TCA 35%). Primary outcome included clinical improvement, patients' satisfaction, and Dermatology Life Quality Index (DLQI). Striae measurement, skin biopsies were also assessed. Very much improvement was achieved in 28%, 44%, and 36% in groups A, B, and C respectively. The combined groups (B and C) showed significantly higher patients' satisfaction and DLQI than group A (p = 0.03), (p < 0.0001). A significant decrease in all striae measurements was achieved with all groups (p < 0.001); however, groups B and C showed more decrease (p = 0.2 and 0.4). A highly significant decrease in the mean number of sessions was found in group B (p < 0.0001). All groups demonstrated improvement in dermal collagen deposition, which was higher in the combined groups. Side effects were mild and well tolerated. The combination of PRP with subcision or peeling was more effective and offered a higher therapeutic response than PRP alone. Moreover, the subcision has superior efficacy in striae albae and safer in darker skin types.

New Progress in Therapeutic Modalities of Striae Distensae

“… 33 It has also been shown that PRP and carboxytherapy are essentially equivalent in the treatment of SA. 34 This year, Ebrahim et al 35 researchers tried the superiority of PRP combined with subcision or peeling/medium-depth peeling (GA 70% + TCA 35%) compared to PRP alone. After clinical improvement, patients’ satisfaction and Dermatology Life Quality Index (DLQI), and skin biopsy assessments, it was confirmed that both combined treatments were superior to PRP alone.…”
