What having Botox involves?
Botox (Botulinum toxin) injections relax the muscles in your face to smooth out lines and wrinkles, such as crow's feet and frown lines. It's not permanent – it usually lasts for around 3 or 4 months.
Your face will be cleaned and botulinum toxin will be injected into muscles in your face using a very fine needle.
You'll need injections in different places, depending on the area being treated. You'll be asked to move the muscles in your face to help find the best place for the injections.
It usually takes about 10 minutes.
When Botulinum toxin is injected, it affects the nerves in the area just around where it is injected. Usually the effect only spreads for a few millimetres or up to a centimetre. This spread can be controlled by changing the volume injected and the amount of toxin in the solution. A trained clinician will therefore consider both the volume they are injecting as well as the dose and the grade of muscle/ gland activity. Researchers discovered in the 1950s that injecting overactive muscles with minute quantities of botulinum toxin type-A would cause a decreased muscle activity by blocking the release of acetylcholine at the neuromuscular junction, thereby rendering the muscle unable to contract for a period of 3 to 4 months.
As of 2007, Botulinum toxin injection is the most common cosmetic operation, with 4.6 million procedures in the United States, according to the American Society of Plastic Surgeons.
