Comparative Study to Evaluate the Efficacy of Two Microneedling Therapies for Acne Scar Treatment

Abstract

Microneedling is a minimally invasive procedure based on collagen induction therapy and helps reduce the appearance of acne scars. The aim of the present study is to evaluate and compare skin firmness, elasticity, and improvement of skin texture and reduction of facial erythema after sessions of microneedling procedure performed by using two different devices, i.e., the manual microneedle roller and automated microneedle stamp. A randomized comparative clinical study was conducted. Research subjects in one group were applied with the manual microneedle roller, and those in the other group were applied with the automated microneedle stamp. They were subjected to four months of treatment (4 sessions with a microneedling procedure at 28-day intervals). Skin firmness and elasticity were performed by Cutometry measurement. Subjects were photographed for skin texture and erythema evaluation. It was observed that the microneedling procedure using both devices - microneedle roller and stamp- significantly improved skin firmness and elasticity. The treatment also promoted reductions in the intensity of scar and erythema, respectively. The devices promoted similar beneficial results without significant differences between them. The present study demonstrates that both the manual microneedle roller and automated microneedle stamp comparably resulted in an improvement of skin firmness, elasticity, reduction of facial scar, and erythema.
