Botulinum toxin type A is produced by a specific bacteria that causes a type of food poisoning, botulism. Botox — the brand name for medicinal botulinum toxin type A — is the purified low-concentration form of the toxin. When injected in small doses into specific muscles, Botox blocks the chemical signals that cause muscles to contract. When the muscles can’t tighten, the skin flattens and appears smoother and less wrinkled.
Botox injections temporarily relax the facial muscles that underlie and cause wrinkles, making them appear less noticeable. The Food and Drug Administration (FDA) has approved Botox for adults ages 18 to 65 as a temporary treatment for moderate to severe frown lines between the eyebrows. However, Botox has been used to treat other facial wrinkles as well, such as the lines that fan out from the corners of the eyes (crow’s-feet) and the forehead furrow.
Rejuvenation of the lips, folds around the mouth and under the eye are commonly requested and performed procedure. There are numerous strategies for treating these areas. One of the basic approaches is to add volume. Usually through injectable fillers, volume can be added. This is based on the fundamental belief that volume loss is a significant part of the aging face.
