Analysis on the Effect and Safety of 500 nm Delicate Pulse Light in the Treatment of Rosacea
Objective To analyze the clinical effect and safety of 500 nm delicate pulse light(DPL)in the treatment of rosacea.Methods 100 patients with rosacea admitted to our hospital from March 2018 to April 2021 were randomly divided into control group(n=50)and observation group(n=50).The control group was treated with symptomatic drugs,while the observation group was treated with 500 nm DPL on the basis of the control group.The clinical effect and safety of the two groups were compared.Results The scores of erythema,papules,pustules and telangiectasia in the observation group after treatment were lower than those in the control group(P＜0.05).The total effective rate of treatment in the observation group was 96.00％,higher than 84.00％in the control group(P＜0.05).No statistical difference was found in the incidence of adverse reactions(8.00％vs.6.00％)during treatment between the two groups(P＞0.05).Conclusions 500 nm DPL has significant efficacy,and is safe and reliable in the treatment of rosacea,which is worthy of clinical promotion and application.
