Botulinum Toxin A)Botulinum toxin (Type A) is a cosmetic injection that blocks the nerve signals that cause muscles to contract. This effect relaxes and smooths the look of lines and wrinkles caused by repetitive movements on the face—most commonly, between the brows, crows-feet around the eyes, and horizontal forehead creases.
Botulinum toxin is also used cosmetically to balance facial asymmetry and relax tight neck bands, as well as medically to reduce perspiration, treat migraine headaches and muscle spasticity.
