Treatment of wrinkles with botulinum toxin is, since its beginnings in the late 90s, one of the stars of cosmetic procedures worldwide. It was the Americans who labeled it a "lunchtime procedure" because it's the kind of procedure you do in five minutes, on your lunch break.
The speed of the procedure, the fact that it does not require subsequent recovery and last but not least the fact that it can remove several years from the face in a few minutes make botulinum toxin injections for cosmetic purposes gain more and more fans every day.
