Botox (Allergan) and Xeomin (Merz) are all injectable neuromodulators, meaning they can temporarily alter the nerve impulses of targeted muscles, therefore reducing or eliminating contraction-induced wrinkles.
Each brand has a slightly different formulation of the same substance, bacterium Clostridium Botulinum, or Botulinum Toxin A, but they all work the same way: they block the nerve impulses of the injected muscles to temporarily paralyze muscle movements that cause wrinkles. The most common targets are horizontal lines across the forehead and perpendicular frown lines between the brows (also called “The Elevens”), but many also rely on Botox and Xeomin for crow’s feet, nasal squint lines and eyebrow lifting.
When administered properly, the effects are confined to the injection zone and do not affect the surrounding areas or travel around the body, as commonly feared.
By reducing the intensity and frequency of contraction-induced wrinkles, these treatments also prevent the formation of deeper lines in the long run, making them an increasingly popular anti-aging strategy.
