In scientific terms, BOTOX® is a purified protein toxin that is produced by the clostridium botulinum bacteria. In the simplest of terms, BOTOX® is a drug that causes a temporary weakness of a muscle. It is safe and has been used in Ophthalmology and wrinkle therapy for over ten years.
Many wrinkles are actually creases that have been worn into the skin by making certain facial expressions thousands of times. These lines are due to the contraction of the muscle under the skin and not actual sagging or aging of the skin. When injected into the muscle causing the contraction, Botox® relaxes the muscle which results in the overlying skin being softened and smoothing out the lines. The results of the injections normally last 3 to 6 months.
BOTOX® is most commonly used on the frown lines between the eyebrows, on the horizontal lines across the forehead and on the crow’s feet. The injection takes just a few minutes and patient’s normally experience only minimal discomfort, often described as a stinging, for a few seconds. It does not affect nerves of sensation, so there is no numbness in the treated area. The effect of BOTOX® is only in the immediate area of the injection. The other muscles used for expressions are unaffected.
