Objective To investigate the clinical effect and safety of traditional Chinese medicine powder mask combined with intense pulsed light in the treatment of rosacea with lung and stomach hyperthermia type and heat toxin accumulation skin type. Methods A total of 80 rosacea patients with lung and stomach hyperthermia type and heat toxin accumulation skin type admitted to our hospital from June 2022 to May 2023 were selected as the research subjects, and they were randomly divided into control group and experimental group, with 40 patients in each group. The control group was treated with intense pulsed light and the experimental group was treated with traditional Chinese medicine powder mask and intense pulsed light. The clinical efficacy, traditional Chinese medicine symptom score, quality of life and adverse reactions were compared between the two groups. Results The total effective rate of treatment in the experimental group was 52.50%, which was higher than 20.00% in the control group, and the difference was statistically significant (P <0.05). After treatment, the traditional Chinese medicine symptom score in the two groups was lower than that before treatment, and that in the experimental group was lower than that in the control group, and the difference was statistically significant (P <0.05). After treatment, the DLQI score in the two groups was lower than that before treatment, and that in the experimental group was lower than that in the control group, and the difference was statistically significant (P <0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P >0.05). Conclusion The combination of traditional Chinese medicine powder mask and intense pulsed light in the treatment of rosacea with lung and stomach hyperthermia type and heat toxin accumulation skin type is ideal, which can effectively reduce the clinical symptoms and improve the quality of life of the patients, without increasing the incidence of adverse reactions. It is worthy of clinical application.
