Abstract:
Objective:To evaluate the clinical efficacy and safety of intense pulsed light combined with fruit acid in the treatment of erythema and pigmentation after facial acne.Methods:From January 2019 to December 2022, 108 patients were selected from Dermatology Hospital of Guangxi Zhuang Autonomous Region, including 30 males and 78 females, aged 20-44 (28.2±5.1) years. The patients were divided into three groups: intense pulsed light group (40 cases), fruit acid group (38 cases) and intense pulsed light combined with fruit acid group (30 cases). The clinical efficacy of the three groups was compared. The facial biological characteristics data of patients were collected with VISIA skin analyzer and the changes compared before and after treatment in each group.Results:The total effective rates of the intense pulsed light group, the fruit acid group and the combination group were 57.5% (23/40 cases), 50.0% (19/38 cases), and 80.0% (24/30 cases), respectively. Comparison of total effective rates among three groups, there were statistically significant differences (χ 2=6.70, P=0.04). Comparison of effective rates among different groups showed that there was no difference between the intense pulsed light group and the fruit acid group (χ 2=0.44, P=0.51); there were significant difference between the intense pulse light group and the combination group (χ 2=3.93, 6.49; P<0.05), and between the fruit acid group and the combination group (χ 2=6.49, P=0.01). After treatment, the VISIA scores of erythema, spots, pores, and purple in three groups of patients significantly decreased compared to before treatment ( P<0.05). The VISIA scores of each observation value showed a decreasing trend with the increase of treatment frequency ( P<0.01). During the treatment, no obvious adverse reactions were observed. Conclusions:Intense pulsed light combined with fruit acid in the treatment of facial erythema postacnes and postinflammatory hyperpigmentation can improve the efficacy and less adverse reactions.
