Microneedling combined with platelet-rich plasma or trichloroacetic acid peeling for management of acne scarring: A split-face clinical and histologic comparison

Summary

Background

Minimally invasive procedures provide effective, safe, relatively long-lasting, and natural results without large damage to the skin. A combination treatment is considered an approach that includes at least 2 different and unrelated modalities.

Objectives

This study aims to evaluate the use and effectiveness of some combined minimally invasive procedures for management of acne scarring.

Patients/methods

Twenty-four volunteers with postacne atrophic scars were randomly divided into 3 equal groups according to performed procedure on each side of the face (microneedling by dermaroller alone or combined with platelet-rich plasma [PRP] or trichloroacetic acid [TCA] 15% peeling) and received 6 bi-weekly sessions of treatment. Photography and punch biopsies were taken before and after 3 months of treatment for clinical, histological, and histometrical evaluation.

Results

Combined treatment of dermaroller and PRP or dermaroller and TCA 15% showed significant improvement when compared with dermaroller alone (P = .015 and .011 respectively). Epidermal thickness showed statistically significant increase in studied groups, mainly after dermaroller and TCA 15%. Moreover, the 3 studied groups showed more organized collagen bundles and newly formed collagen formation and markedly decreased abnormal elastic fibers.

Conclusions

Based on the clinical, histometrical, and histochemical assessment, inspite that most volunteers showed significant improvement after treatment, however, the combined use of dermaroller and TCA 15% was more effective in postacne atrophic scars than the use of dermaroller and PRP or dermaroller only.
