Abstract:
Erythema and scarring are among the most common complications of severe inflammatory acne. In this study, we aimed to share our experience with pro-yellow laser and document the efficacy and safety of this treatment in postacne erythema and scarring. The study included 40 patients, 24 (60%) females, and 16 (40%) males with a mean age of 29.5 ± 8.16 (min. 18 years, max. 57 years). The pro-yellow laser was applied to all patients as a single session with irradiation of 22 J/cm2. Improvement in postacne erythema and scars were evaluated after the treatment. The study included 40 patients, 24 patients (60%) were females and 16 patients (40%) were males with the mean age of 29.5 ± 8.16 (ranged between 18 and 57 years old). A total of 21 patients (52.5%) had good improvement (51%-75% regression), 10 patients (25%) had excellent improvement (76%-100% regression), and a moderate improvement (26%-50%) was detected in 9 patients (22.5%). Also, there were mild improvement (1%-25%) in 20 patients (76.9%) and a moderate improvement (26%-50%) in 6 patients (23.1%). We found that pro-yellow laser is highly effective in the treatment of postacne erythema, while its effectiveness was mild to moderate in atrophic acne scars. Also, it has been observed that the pro-yellow laser system can be used safely immediately after cessation of systemic isotretinoin treatment. © 2020 Wiley Periodicals LLC.
