BOTOX®/Dysport® injections block the chemical signal that the brain sends to the muscle telling the muscle to contract. This means that when the brain says ‘squint, it’s sunny’, the muscles are saying ‘I can’t hear you. In effect the treatment relaxes and lifts the muscle, softening the look of lines and giving a tighter, smoother appearance.
It generally takes 3 to 10 days after the treatment for the maximum to develop fully and re-treatment should not occur within that period. The effect generally lasts 3 to 4 months, although with regular treatments it may be possible to reduce the dosage.
