Facial furrows form mainly in response to normal aging and the pull of underlying muscles. Botox works by decreasing the pull of these muscles thereby allowing treatment of some skin creases without surgery.
Botox is the brand name for botulinum toxin type A, nature’s most potent blocker of nerve impulses. Botox works by partially blocking the nerve to the injected muscle.
Botox injections are best on the upper third of the face. Forehead lines, furrows between the eyebrows, and lines around the eyes (crow’s feet) respond favorably to Botox. Frown lines (below the mouth) and chin creases may also be improved with a Botox injection, but response here varies by individuals.
Please remember, Botox injections are temporary. The effect wears off in about four to six months. If desired, the injection may be repeated, and modified to achieve a different result each time.
