Abstract :

Objective: This study investigates the potential efficacy of intense pulsed phototherapy (IPP) within two specific wavelength ranges (400-600 nm and 800-1200 nm) as a novel therapeutic approach for managing mild-to-moderate instances of acne vulgaris affecting the facial region. The efficacy of intense pulsed light (IPL) against P. acnes and its potential soothing effects on the skin prompted our investigation into its safety for this specific use.
Materials and Methods: In a prospective study conducted at a single site, 15 patients with Fitzpatrick skin types III-IV and mild-to-moderate facial acne vulgaris received five IPL treatments using a dual- band “notch” acne filter (Lumenis M22 System) at 1–4 week intervals. The Pictures were taken for Assessment before the treatment and after the 5 session of treatment was performed, the evaluation included the 5-point Global Aesthetic Improvement Scale (GAIS) for acne severity, lesion counts, and overall appearance improvements, as well as Cardiff Acne Disability Index (CADI) questionnaire responses, satisfaction ratings, and pain.
Results: The GAIS scores show that dual-band phototherapy greatly enhanced the cosmetic outcomes. Average GAIS scores decreased from 3.07 ± 0.22 to 2.07 ± 0.29 after the first week of treatment (5 sessions) and they remained significantly lower after a month (mean GAIS 0.47). Significant improvements in acne-related impairment were also shown by the CADI scores, which dropped from a baseline value of 9.47 ± 7.64 to 7.0 ± 5.29 after one week and further to 4.73 ±
3.09 after Four weeks. These findings demonstrated the significant psychological and cosmetic benefits of dual-band phototherapy.
Conclusion: Using IPL equipment with a “notch acne filter,” this study shows significant acne vulgaris lesions reduction. Additionally, the treatment was safe and well-tolerated. These data support dual-band IPL therapy for mild-to-moderate facial acne vulgaris, improving aesthetic appearance and psychosocial well-being.
