Abstract
BACKGROUND: Postacne scarring is an unfortunate and frequent complication of acne, with varied morphological forms and associated significant psychological distress to patients.
AIM OF THE WORK: To evaluate the efficacy and safety of plasma gel injection alone and in combination with microneedling in treatment of atrophic postacne scars.
PATIENTS AND METHODS: Sixty patients with atrophic postacne scars were enrolled in this single blinded randomized controlled study. The patients were divided into three groups with 20 patients being treated with intradermal injection of plasma gel, 20 patients treated with dermaroller, and 20 patients subjected to combined plasma gel and dermaroller. Patients received four sessions at monthly intervals and were evaluated by clinical, histopathological, and immunohistochemical analysis.
RESULTS: There was statistically significant improvement in postacne scars after treatment in all studied groups with variable degrees; the combined technique showed the best clinical improvement in postacne scars. There was an increase in newly formed collagen and elastic fibers with more organized and condensed bundles after the end of treatment.
CONCLUSION: Plasma gel showed a remarkable improvement for most patients after one session, providing a quick and easy solution for acne scars. The combination of dermaroller and plasma gel potentiated its effect with more improvement in scars.
