Efficacy of alpha hydroxy acid combined with intense pulsed light in the treatment of acne vulgaris: A meta-analysis.

BACKGROUND

Acne patients frequently receive combination therapy. However, there has been no rigorous review of the efficacy of combining alpha hydroxy acid with IPL for acne vulgaris treatment.

OBJECTIVE

Assessing the effectiveness and safeness of alpha hydroxy acids in combination with IPL in the treatment of people with acne vulgaris.

METHODS

A computer search of common biomedical databases, including PubMed, Web of Science, Cochrane Library, Embase, Wanfang, CNKI, SinoMed, and VIP, was extensively conducted to identify previous studies on randomized controlled trials of alpha hydroxy acid combined with IPL in the management of acne vulgaris.

RESULTS

A total of 18 publications were included (1435 patients with common acne met the inclusion criteria). The meta-analysis showed that alpha hydroxy acid (AHA) combined with IPL had higher overall efficacy than the control group (OR = 4.24; 95% CI 2.66 ~ 6.74; p < 0.01). In the case of acne vulgaris, AHA combined with IPL and the AHA alone showed a remarkable difference in total efficiency (OR = 4.10; 95% CI 2.12 ~ 7.91; p < 0.01), and AHA combined with IPL were more effective than IPL alone (OR = 4.02; 95% CI 2.25 ~ 7.16; p < 0.01). In addition, the occurrence of adverse reactions that occurred in AHA combined with IPL and control groups did not differ (OR = 0.86; 95% CI 0.46 ~ 1.60; p = 0.64).

CONCLUSION

AHA combined with IPL therapy was superior to other therapies. Although it was slightly more expensive, it was effective and had a wide range of applications.
