Evaluation of the Efficacy of Platelet-Rich Plasma Injections With and Without Microneedling for Managing Atrophic Facial Acne Scars: A Prospective Comparative Study.

Background and aim The majority of acne has the potential to transform into facial scars, which have a physical and psychological effect on the individual. There are plenty of treatment options to manage such scars. The aim of this study is to assess the comparative effect of the injection of platelet-rich plasma (PRP) alone, with that of the injection of PRP with microneedling, in the reduction of atrophic facial acne scars.  Methods A total of 30 participants were included in this study, divided into two groups (n = 15). Patients in Group I received intradermal injection of PRP only, and Group II included patients receiving intradermal injection of PRP with microneedling. The scar appearance was evaluated at baseline, after one, two, and three months using Goodman Baron's scar scale. The statistics were analysed using the Chi-square and Student's t-tests.  Results Patients in the PRP with microneedling group had lower acne scar scores on the Goodman Baron scale compared to those who received only PRP. The acne scores were statistically significant (p-value < 0.05) in the second and third months of treatment in Group II.  Conclusion The addition of microneedling to PRP has proven to be effective in the reduction of facial acne scars. However, different types of scars require different modalities of treatment, and the final decision lies in the hands of the operator and the requirements of the patients.
