Combined autologous platelet-rich plasma with microneedling verses microneedling with distilled water in the treatment of atrophic acne scars: a concurrent split-face study.

Abstract

BACKGROUND:
Acne scarring causes cosmetic discomfort, depression, low self-esteem and reduced quality of life. Microneedling is an established treatment for scars, although the efficacy of platelet-rich plasma (PRP) has not been explored much.

OBJECTIVE:
The objective of this study was to evaluate the efficacy and safety of platelet-rich plasma (PRP) combined with microneedling for the treatment of atrophic acne scars.

METHODS:
Fifty patients of 17-32 years of age with atrophic acne scars were enrolled. Microneedling was performed on both halves of the face. Intradermal injections as well as topical application of PRP was given on right half of the face, while the left half of the face was treated with intradermal administration of distilled water. Three treatment sessions were given at an interval of 1 month consecutively. Goodman's Quantitative scale and Quantitative scale were used for the final evaluation of results.

RESULTS:
Right and left halves showed 62.20% and 45.84% improvement, respectively, on Goodman's Quantitative scale. Goodman's Qualitative scale showed excellent response in 20 (40%) patients and good response in 30 (60%) patients over right half of the face, while the left half of the face showed excellent response in 5 (10%) patients, good response in 42 (6%) patients and poor response in three patients.

CONCLUSION:
We conclude that PRP has efficacy in the management of atrophic acne scars. It can be combined with microneedling to enhance the final clinical outcomes in comparison with microneedling alone.
