ABSTRACT

Objective:To study the clinical effect of alpha hydroxy acids on facial acne patients.Methods:A total of 36 patients with facial acne who were treated at the Department of Dermatology, Beijing Friendship Hospital from December 1, 2018 to May 31, 2019 were selected. All patients were treated with 20% alpha hydroxy acids. Treatment efficiency, lesions improvement and patients＇satisfaction were evaluated.Results:All evaluation indexes were improved after treatment. Before treatment, patients with acne were classified into grade Ⅰ(9 cases), grade Ⅱ(18 cases ), and grade Ⅲ (9 cases) through Pillsbury Grading, and after treatment, there were 28 cases of grade Ⅰ, 28 cases of grade Ⅱ, and 0 cases of grade Ⅲ, which had statistic differences ( χ2= 22.603, P<0.001). The number of lesions before treatment was 38.64±15.57, and that was 16.17±11.49 after treatment, and the difference was statistically significant ( t=6.967, P<0.001). After treatment, 2 cases were cured, 17 cases were markedly effective, 11 cases were effective, 2 cases were ineffective and 4 cases were worsening. 30 patients were cured, markedly effective or effective, and the total effective rate was 83.33%. The value of skin pores before treatment was 1263.67±593.44, and decreased to 1196.33±579.27 after treatment. The difference was statistically significant ( t=3.155, P<0.05). After the treatment, all the patients were satisfied with the effect. Conclusions:Alpha hydroxy acid is a safe and effective method for acne patients.
