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.
