Acne scars are the ultimate outcome of acne vulgaris, a prevalent skin disorder affecting the pilo‐sebaceous unit. Laser resurfacing has been demonstrated to be an efficient therapy option for acne scars. Hence, we adopted this concept and conducted a study to evaluate the safety and efficacy of low‐energy double‐pass 1450‐nm diode laser on acne scars. This study was conducted on 48 patients with acne scars, treated at 4‐week interval with low‐energy double‐pass 1450‐nm diode laser. Patients were evaluated clinically and with photographs, at day 0, first month and third month post the final treatment and during follow‐up visit. Five treatment sessions were completed by all patients. Approximately, 79.2% of patients showed around 30% improvement. At the end of third month follow‐up, 92.9% of the patients demonstrated >30% improvement. Vesicle formation was observed in two cases, with no post‐inflammatory hyperpigmentation and transient hyperpigmentation was observed in one case, which vanished within 2 months. Our study showed that 1450‐nm diode laser treatment was efficient and well endured in facial acne scars when used with double‐pass at low‐energy.
