Botox Through The Decades: Look Your Best At Every Age (hauteliving.com)

Botulinum Toxin (Botox, Dysport) is an injectable compound derived from the bacterium clostridium botulinum that is used cosmetically to decrease the appearance of fine lines and wrinkles. Botox targets nerve endings of nerves that control muscle movement and acts to reduce the release of a molecule called acetylcholine, which results in decreased muscle contraction. The movement of muscles in the face is the source of lines and wrinkles that appear in the skin. When injected in precise locations, Botox can target specific muscles that produce those facial wrinkles, decreasing their prominence.
