To observe the effect of superion therapy on neck skin relaxation and its effect on neck skin texture. Methods A total of 44 patients with neck skin relaxation admitted to Shenzhen Aoma Xingguang Yuelong Medical Beauty Clinic from January to June 2023 were selected as the research objects. According to different treatment methods, they were divided into control group and observation group, with 22 patients in each group. The control group was treated with conventional therapy, and the observation group was treated with superion therapy. The improvement of neck skin, neck aesthetics, satisfaction and adverse reactions were compared between the two groups. Results After treatment, the dynamic score of neck transverse striation, static score of neck volume, static and dynamic scores of neck relaxation in the observation group were lower than those in the control group, and the differences were statistically significant (P <0.05). The overall cosmetic improvement scores of the observation group were higher than those of the control group after 1,2 and 3 times of treatment, and the differences were statistically significant (P <0.05). The satisfaction of the observation group was higher than that of the control group, and the difference was statistically significant (P <0.05). The incidence of adverse reactions in the observation group was 4.55%, which was lower than 13.64% in the control group, and the difference was statistically significant (P <0.05). Conclusion Superion treatment of neck skin relaxation effect is good, which can effectively improve the neck skin, promote the overall cosmetic improvement, and the incidence of adverse reactions is low, the clinical satisfaction is high.
