Intense pulsed Light, Light-Emitting Diode, and hydroxychloroquine in the treatment of rosacea: A clinical observation.

Background: Rosacea is a common, chronic inflammatory skin condition lacking specific treatment. This study investigates the efficacy of various photoelectric therapies in treating rosacea. 90 rosacea patients who visited the dermatology outpatient clinic of the hospital from August 2022 to November 2023 were analyzed (retrospective registration 20240425). The patients were categorized into three groups based on different treatment methods: the control group received oral hydroxychloroquine sulfate and topical recombinant bovine basic fibroblast growth factor; observation group 1 underwent intense pulsed light therapy in addition to the control group's treatment; observation group 2 received light-emitting diode therapy on top of the control group's regimen. The therapeutic effect was evaluated by physicians' subjective evaluation and patients' pruritus symptoms. The effective rates of observation group 1, observation group 2, and the control group were 73.3%, 66.7%, and 40%, respectively, with statistical significance (P < 0.05). There was no significant difference between observation group 1 and observation group 2 (P < 0.05). Additionally, there were no significant adverse reactions in any of the three groups. The comparison between observation group 1 and observation group 2 revealed that the two combined treatment methods achieved similar and positive therapeutic effects across various clinical manifestations. The effectiveness of both observation groups was found to be superior to that of drug therapy alone.
