Methods A total of 80 patients with sensitive skin admitted to Department of Dermatology, Afffliated Hospital of Xiangtan Medicine&Health Vocational College from January 2022 to December 2024 were selected. According to the random number table method, they were divided into the control group and the observation group, with 40 patients in each group. The control group was given conventional skin nursing guidance and outpatient follow-up, and the observation group was given internet-based health education on the basis of the control group's intervention. The skin health knowledge level, facial aesthetic score, quality of life and satisfaction were compared between the two groups.

After intervention, the VAS score of facial aesthetics in the observation group was higher than that in the control group (P<0.05). After intervention, the score of DLQI in the observation group was lower than that in the control group (P<0.05). The satisfaction rate of the observation group was higher than that of the control group (P<0.05).
