Qu’est-ce que la toxine botulique et comment fonctionne-t-elle ?<\/h2>\n

Botulinum toxin is a purified protein used to relax the muscles responsible for dynamic wrinkles, meaning those that appear with facial movements (such as smiling, frowning or squinting). It works by temporarily blocking the nerve signals that control these muscles, allowing the skin to become smooth and relaxed.
The dynamic wrinkles treated with botulinum toxin injections are forehead wrinkles, crow\u2019s feet wrinkles around the eyes, and frown lines between the eyebrows.
