The primary use of Botox is reducing the appearance of facial wrinkles. The amount used to treat wrinkles and other conditions is extremely small to help prevent poisoning from the toxins while creating the desired cosmetic effect. It may take two to three, and in rare cases up to five days, after treatment before you begin to see notable results in the mirror. Botox is a relatively safe treatment, but it should always be undertaken by a qualified medical professional to ensure that you are getting the correct amount in the right area.
Cosmetic Botox injections work by blocking the nerve signals to certain muscles. The muscles then become more relaxed. This reduces the appearance of lines and wrinkles on the skin. Botox freezes muscle movement by blocking neuro-transmitters and this effect lasts for 4-6 months. You will need top-ups a few times a year if you wish to maintain your line-free look.
However, the FDA have only approved the injections for use around the eyes and on the forehead.
