Understanding Botox and Neurotoxins: Mechanism of Action and Indications for Use

Botox and neurotoxins, such as Dysport and Xeomin, are widely used injectable treatments for reducing the appearance of wrinkles and fine lines. They work by temporarily paralyzing the muscles that cause wrinkles by blocking the release of acetylcholine, a neurotransmitter that stimulates muscle contraction. Botox is commonly used to treat wrinkles in the forehead, glabella, and crow's feet, while other neurotoxins have a variety of medical indications, including the treatment of migraines, excessive sweating, and muscle spasms.
