Botulinum Toxin type A (BTTA), commonly perceived as a “wrinkle relaxer” and referred to as ‘Botox’ is a powerful FDA approved agent of the face. The neurotoxin rebalances the muscle activity of the face with the skin elasticity changes occurring with age. BTTA can selectively relax the injected muscles by temporarily blocking the transmission of nerve signals, allowing the skin to unwind, thus making facial wrinkles and lines less noticeable.
The cosmetic effect is achieved by strategically weakening targeted muscle groups and by carefully choosing the dose of BTTA according to the degree of muscle contraction, anatomic symmetry, and the desired aesthetic goal. Skill in selecting the injection sites and dosages is vital to avoid over-weakening the muscles or creating a non natural looking face.
