Also known as Botox Cosmetic®, Dysport®, Xeomin®, or Botulinum Toxin Type 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 refuse perspiration.
