ERBIUM-YAG LASER ALONE VERSUS ERBIUM-YAG LASER WITH PLATELET RICH PLASMA IN TREATMENT OF ATROPHIC ACNE SCARS

Aim of the work : To evaluate the efficacy of Erbium-YAG laser alone and in combination of platelet-richplasma (PRP) in atrophic post acne scars.Patients and Methods: This study was a prospective non randomized clinical trial. 50 patients wereincluded in this study, examined and divided into two groups. Group A included 25 patients weresubjected to 6 Erbium-YAG laser sessions over 6 months period while group B included 25 patients weresubjected to 6 Erbium-YAG laser sessions plus 12 microneedling sessions with PRP over the same period.Evaluation was carried out through operating physicians, two blinded physicians as well as throughpatient’s satisfaction.Results: Both modalities of treatment showed improvement of acne scars but the improvement withcombined Erbium-YAG laser and PRP was better than Er-YAG laser alone ( p value = 0.0158) with lessside effects and better patients' satisfaction ( p value = 0.022).Conclusion: We concluded that both modalities of treatment are effective and safe in treatment of acnescars but the combination of PRP plus laser was superior to laser alone with higher response and less sideeffects.
