Background
Acne is an inflammatory disorder of the pilosebaceous units. The severity of acne scarring depends on delays in treating acne patients.
Objective
To assess the effect of platelet-rich plasma (PRP) in cases of postacne scar and compare the effect of PRP alone and in combination with microdermabrasion on postacne scars.
Patients and methods
Twenty adult facial postacne scar patients were enrolled. Goodman and Baron's scale and ECCA scale were used to determine the severity of acne scars. PRP was injected after microdermabrasion on the right side of the face, while PRP was injected alone on the left side of the face. This was done regularly each month for three sessions. Evaluation of improvement was assessed by Goodman and Baron qualitative scale and ECCA scale for each patient both at the baseline and 1 month after the last session, along with photography.
Results
There was an increase in the scar outcome in the side treated with combined therapy, but it did not reach a significant level between both sides of the face by all objective methods of assessment.
Conclusions
PRP alone or in combination with microdermabrasion is an effective modality for the treatment of postacne scars.
