Successful treatment of facial vascular skin diseases with a 577‐nm pro‐yellow laser

Abstract

Background Treatment of vascular skin diseases is one of the most important indications of the laser. Aims To evaluate the effectiveness of 577‐nm pro‐yellow laser in the treatment of some vascular skin diseases. Patients/methods Ninety‐five patients with vascular skin diseases were included in this prospective monocentric study. They were classified into: port‐wine stain birthmarks (n = 37), papulopustular rosacea (n = 20), facial telangiectasia (n = 16), and facial erythema (n = 22). All participants received a monthly session of 577‐nm pro‐yellow laser. Follow‐up was done by comparing the photographs before and at every follow‐up visit. Results At the final visit, there was a significant improvement (>50%) occurred in 24/37 (64.82%), 12/20 (60%), 10/16 (62.5%), and 19/22 (86.3%) cases and poor response occurred in 6/37 (16.2%), 2/20 (10%), 2/16 (12.5%), and 0/22 cases after a mean number of sessions 7.76 ± 2.28, 3.1 ± 1.8, 3.63 ± 1.12, and 1.8 ± 0.85 in port‐wine stain, rosacea‐, facial telangiectasia‐, and facial erythema‐treated groups, respectively. Transient irritation and erythema during the session were the only complications reported in the study. Conclusion Facial port‐wine stains, rosacea, telangiectasia, and erythema can be successfully treated with a single pass of 577‐nm pro‐yellow laser with a minimal side effect. Facial erythema showed the highest degree of success with the least number of sessions, while more sessions needed for the treatment of port‐wine stain.

Successful treatment of poikiloderma of Civatte with a 577‐nm pro‐yellow laser

“…The short pulse time and specificity of the interaction between yellow light and hemoglobin permit this method to be applied without structural changes or scarring. 4 To the best of our knowledge, this is the first reported case of a 577-nm pro-yellow laser for the therapy of poikiloderma of Civatte.…”

Efficacy of 577‐nm Pro‐Yellow laser in port wine stain treatment

“…PWSs required longer sessions. They considered this laser safe for treating vascular lesions effectively (Mohamed, Mohamed Tawfik, & Hassan Ahmad, ).…”

The efficacy and safety of a 577‐nm high‐power optically pumped semiconductor laser in the treatment of postacne erythema

“…15 The 577-nm yellow laser was introduced more than 20 years ago for the treatment of diabetic retinopathy, but has only been utilized in the field of dermatology in the past 2 years. 9,[16][17][18] This laser emits 100% yellow light, which allows it to specifically target oxyhemoglobin in vascular lesions, but with less absorption in melanin and a slightly deeper penetration into the dermis, thereby minimizing the risk of hyperpigmentation especially in patients with darker skin types. 9,15 The main chromophore for facial erythema is oxyhemoglobin which has three peak points-one at 418-nm, 542-nm and at 577-nm in visible light.…”

“…On the other hand, a study by Mohamed in 2019 looked into the effectiveness of the 577-nm laser not only for PWS birthmarks, but also for papulopustular rosacea, facial telangiectasia, and facial erythema, with the most success (63.6% of cases with excellent results) seen in the latter. 17 The setting used to treat rosacea and facial erythema patients ranged between F 12 and 16 J/cm 2 with pulse duration from 20 to 26 ms, and was done at 1-month intervals for a maximum of 5 sessions. In may be noted that in the above-mentioned study, the laser parameters used for facial erythema are quite similar to the range used in this study (F 10-16 J/cm 2 , 30 ms).…”

“…9,15 The main chromophore for facial erythema is oxyhemoglobin which has three peak points-one at 418-nm, 542-nm and at 577-nm in visible light. 9,15,17 Because of its ability to specifically target oxyhemoglobin, the 577-nm pro-yellow laser has been deemed ideal for vascular lesions by having an additional advantage over the copper bromide laser (composed of 90% yellow light and 10% green light) of minimizing risk of hyperpigmentation in patients of darker skin types. Other than this, other benefits of the 577-nm laser over the other lasers and energy-based devices include its ergonomic quality in that it does not require an expensive dye kit such as in the more widely used PDL, nor a cooling device or coupling gel such as in IPL.…”
