Botox, short for Botulinum toxin, is a purified substance that temporarily relaxes muscles, thereby reducing the appearance of wrinkles and fine lines. Contrary to popular belief, Botox is not a filler; instead, it works by blocking nerve signals to the muscles, preventing them from contracting. This results in smoother, more youthful-looking skin. Despite its widespread use, there are still misconceptions surrounding Botox, including fears of a frozen expression or harmful side effects.
