The so called “expression wrinkles” are deeply marked due to making certain gestures, such as frowning, laughing or raising eyebrows.
Relaxing facial treatment involves injecting botulinum toxin type A in these muscles, to prevent shrinkage. The dose required is very small and is injected with a very fine needle, so the treatment is not painful.
When the muscle stops contracting, wrinkles disappear or is minimized. Three or four days after treatment, the skin remains smooth and unwrinkled, and the patient acquires a relaxed and tranquil appearance.
The treatment is usually performed in a single session that lasts only twenty minutes, after which the patient can return to normal life.
The relaxing effect of botulinum toxin gradually disappears as the nerve endings in the muscles regenerate, so within a period of up to six months the muscle mobility is recovered. If you want to keep the skin smooth and wrinkle free longer, treatment must be repeated.
