Botulinum toxin for mouth lines: eliminate barcode
In summary: botulinum toxin for the mouth relaxes the perioral muscles to smooth the "barcode" lines around the lips caused by repeated expressions. It requires 4-8 units, results appear in 3-5 days with maximum effect at 14 days, and last 3-4 months.
Perioral lines, known as the "barcode," appear around the mouth from repeated expressions. They form when pursing the lips, smoking, or drinking through a straw, and over time these dynamic expression lines become static wrinkles that add years to your appearance.
At our clinic in Bogotá, botulinum toxin (Neuronox or Dysport) is the treatment of choice to smooth them effectively, safely, and naturally.
Dr. Tatiana Leal, aesthetic medicine doctor, uses botulinum toxin to treat the perioral area, achieving natural results that maintain smiling and speaking ability.
The treatment relaxes muscles responsible for vertical lines, allowing a more youthful and fresh appearance without looking artificial.
This is one of the most requested treatments at our Bogotá practice.

Why do lines appear in the mouth
Perioral lines appear from repeated contractions of mouth muscles, such as smoking, straw drinking, or facial expressions. Over time, they become permanent wrinkles.
Causes of barcode
Factors such as aging, sun, and habits contribute. Botulinum toxin relaxes these muscles to smooth lines.
1. Barcode lines (vertical lines)
These are the fine, vertical lines on the upper lip, caused by the repeated contraction of the muscle when pursing the lips (smoking, using a straw). Botulinum toxin is the ideal treatment for these dynamic lines.
2. Marionette lines (nasolabial folds)
These are deeper grooves running from the corners of the mouth toward the chin. They give a sad appearance and usually combine volume loss with skin laxity. For these, hyaluronic acid filler tends to be more effective.
