Objective To analyze the clinical effect of skin beauty treatment for pigmentation after facial burn. Methods A total of 100 patients with facial burn pigmentation admitted to our hospital from January 2018 to November 2022 were selected as the research objects. They were divided into control group and observation group according to the random number table method, with 50 patients in each group. The control group was given routine treatment, and the observation group was given skin beauty treatment. The clinical efficacy, facial appearance recovery time, disease cure time and pigment value improvement were compared between the two groups. Results The total effective rate of treatment in the observation group was 96.00%, which was higher than 68.00% in the control group (P <0.05). After treatment, the pigment value of the observation group was lower than that of the control group (P <0.05). The facial appearance recovery and disease cure time of the observation group were shorter than those of the control group (P <0.05). Conclusion Skin beauty has a good effect on the rehabilitation of patients with pigmentation after facial burn, which can effectively improve pigmentation and promote the recovery of skin lesions. It is worthy of clinical application.
