Anti-Wrinkle Injections - How Botulinum toxin works....
Acetylcholine is the neurotransmitter which passes from the nerve ("axon" in the picture - right) to the muscle fibre, and which makes the muscle contract. Over time and with repeated contractions this can cause wrinkles to form.
Botulinum toxin attaches to the end of the nerve and prevents the release of acetylcholine, thus preventing the contraction of the muscle fibre. As the muscle cannot contract (is temporarily paralysed) the area of skin will appear smoother and wrinkle free.
With time the nerve ending regains the ability to release acetylcholine and muscle activity will be slowly regained - clients may notice their wrinkles start to return at this point.
Botulinum toxin is used in anti-wrinkle injections to smooth out facial wrinkles and improve facial appearance.
