What is a "Botox injection"?

A Botox injection is a medical procedure where a small amount of botulinum toxin is injected into muscles to temporarily weaken or disable them. This treatment is commonly used to reduce wrinkles, treat muscle spasms, or manage certain medical conditions like excessive sweating or migraines. The toxin blocks nerve signals that cause muscles to tighten, resulting in smoother skin or relief from muscle stiffness and pain. Botox injections involve minimal discomfort and typically provide noticeable results within a few days, lasting for several months before needing to be repeated.
