Year: 2025
Type: article
Study design: Clinical Trial
Abstract: BACKGROUND: Nasal blackheads, caused by the obstruction of hair follicles by sebum and exfoliated dead cells, represent a cutaneous issue that impairs facial aesthetics. Current therapeutic outcomes for this problem remain suboptimal. AIMS: To evaluate the effectiveness and safety of a novel treatment mode (advanced OPT with medium energy, three pulses, long pulse width, AOPT-MTL) for the treatment of nasal blackheads. PATIENTS/METHODS: A total of 42 patients with nasal blackheads were enrolled and treated using the AOPT-MTL mode at intervals of 2-3 weeks for a total of 6 sessions. One month after the treatment was completed, the severity of nasal blackheads was assessed using the Enlarged Pore Classification Grade, and the treatment effectiveness rate was calculated. Patients were followed up for 6 months to evaluate recurrence, safety, and satisfaction. RESULTS: After a course of treatment, the nasal blackheads of all patients were improved to varying degrees, and the treatment effectiveness rate reached as high as 95.2%. The Enlarged Pore Classification Grade score decreased from 5.40 ± 0.66 to 2.90 ± 0.61 (p < 0.05). No significant adverse reactions were observed during treatment. Recurrence was minimal during follow-up, and patient satisfaction remained high. CONCLUSIONS: The AOPT-MTL mode offers a simple, effective, and safe treatment option for nasal blackheads in Asians. With its demonstrated efficacy and good safety profile, it holds great promise for extensive clinical application.
