    Abstract:
    Acne scarring causes cosmetic discomfort, depression, low self-esteem and reduced quality of life. Microneedling is an established treatment for scars. A multimodality approach to scar treatment is usually necessary to achieve the best cosmetic results. The objective of this study was to evaluate the efficacy and safety of platelet rich plasma (PRP) combined with microneedling in comparison with microneedling with non-cross-linked hyaluronic acid for the treatment of atrophic acne scars. Forty-one patients of 20-40 years of age with atrophic acne scars were included. Microneedling was performed on both halves of the face. Topical application of PRP was given on right half of the face, while the left half of the face was treated with topical application of non-cross-linked hyaluronic acid. Four treatment sessions were given at an interval of 1 month consecutively. Goodman's Qualitative scale and the quartile grading scale are used for the final evaluation of results. There was a statistically significant improvement in acne scars after treatment among the studied group. Right and left halves showed 85.4% and 82.9% improvement, So the difference of the improvement between the two modalities is statistically insignificant P > 0.05 We conclude that microneedling has efficacy in the management of atrophic acne scars. It can be combined with either PRP or noncross-linked hyaluronic acid to enhance the final clinical outcomes in comparison with microneedling alone. The difference between the two modalities is insignificant.
