Botulinum toxin A (BTA) is a substance found in the bacteria Clostridium botulinum. The main function of BTA is blockade of signal transmission at the nerve endings. In clinical practices, BTA can be used to weaken a particular muscle or muscle group, reduce autonomic nervous activity in a particular glands and also block a specific group of afferent nervous system that transmit pain sensation. In cosmetic practice, BTAs are injected into discrete facial muscles where they act locally to reduce muscle contractions that produce skin creases. The main result is disappearance of facial wrinkles. BTA can also be used to elevate saggy brow and provide lifting to saggy facial skin (Nefertiti Lift).
