Abstract

Background

Photodynamic therapy had made great progress in the treatment of acne vulgaris. However, there is no meta-analysis on the effectiveness and safety of red light therapy for acne vulgaris.

Objective

To assess the efficiency and safety of red light therapy for acne vulgaris.

Methods

PubMed, Cochrane Library, EMBASE, and Web of Science were retrieved to identify related studies. The outcomes were expressed as improvement in the average percentages of inflammatory acne lesions (MPRI) and non-inflammatory acne lesions (NMPRI), as well as the improvement of acne lesions respectively after treatment.

Results

13 randomized controlled trials (RCTs) consisting of 422 participants were included. There was no significant difference in the average number of non-inflammatory lesions (weighted mean difference (WMD = -0.527; 95% CI,-3.055~2.001; p = 0.683). Moreover, there was no statistically significant difference in the average number of inflammatory lesions (WMD =0.701; 95% CI, -0.809~2.212; p =0.363). In the subgroup analysis of the outcome changes in comedones, pustules, papules, and total lesions, it was found that red light therapy elicited no significant superiority compared with other conventional treatment methods (WMD = -1.125; 95% CI, -3.122~0.873; p = 0.270). Adverse events of the red light group were generally mild or even completely non-existent.

Conclusion

There was no statistically significant difference between red light therapy and traditional therapies in terms of efficacy. However, due to the heterogeneity of the researches and the lack of large sample size, the result of this study needs to be interpreted with caution.
