Abstract

BACKGROUND

Currently, there is no standardized approach for eyebrow shaping with botulinum toxin, and controversies still exist regarding this subject.

OBJECTIVE

The objective of this systematic review is to summarize and compare all the published data regarding eyebrow shaping with botulinum toxin.

METHODS

On March 10, 2017, an online search of published articles in the Medline, Embase, and Cochrane databases were conducted. All articles that used objective measurements to quantify the eyebrow changes after botulinum toxin injection were included in this review.

RESULTS

Eleven studies were selected for inclusion with a total of 585 patients. All the included studies used onabotulinumtoxin A. Seven studies injected both the lateral and the medial eyebrow depressors, 2 studies injected the lateral depressors alone, and 2 studies injected the medial depressors alone. The highest elevation was observed in the lateral brow (0.4–4.8 mm). Bruising and headache were the most frequently reported complications, and only 5 cases of eyelid ptosis were noted.

CONCLUSION

Botulinum toxin injection for eyebrow shaping is a noninvasive, safe, and reproducible procedure. Eyebrow reshaping can be achieved by targeting different muscle groups. However, further randomized controlled trials are warranted.
