Abstract

Background: Laser is a more promising option for post-acne scar treatment than other modalities. The process involved stimulating fibroblasts to fill and finish the scar defect, replacing the lost collagen and elastin dermal components. Methods: : A total of 25 patients with different skin types suffering from mild, moderate and severe facial acne scars, were split face group: ( Rt side with Long pulsed 1064nm Nd-YAG laser and Lt side with Q-switched 1064nm Nd-YAG laser)Results: There was statistical significance differences in number of sessions among Rt side compared to Lt side. Also there was decrease in frequency of inflammation among Lt side compared to other side, and decrease in frequency of bleeding and edema among Rt side compared to other side and finally increase in frequency of hyperpigmentation Lt side compared to Rt sideConclusion: Q-switched and long-pulsed 1064 nm Nd-YAG lasers are considered an efficient and safe modality for the treatment of mild to moderate post-acne facial scars, particularly in elderly patients (30-40 years of age) with type 4 skin without the need for downtime, and in this study their daily activity was not disturbed, but we found that Q-switched is more effective and satisfied.
