Treatment of Glabellar Frown Lines with C. Botulinum‐A Exotoxin

Abstract
Eighteen patients with glabellar frown lines were treated with C. botulinum‐A exotoxin. Sixteen of the 17 patients followed showed improvement for periods ranging from 3 months to 11 months. Side‐effects were minimal and transient. Because C. botulinum‐A exotoxin therapy of glabellar frown lines treats the underlying cause of these lines, it is more effective than soft tissue augmentation although this improvement is temporary. Treatment with C. botulinum‐A exotoxin is a simple, safe procedure.
