Botox, or Botolinum toxin is a neurotoxin that is commonly used for cosmetic and medical purposes. When injected into muscles, it temporarily paralyzes them, reducing the appearance of wrinkles and fine lines by preventing muscle contractions. Botox is often employed in aesthetic treatments to achieve smoother and younger-looking skin, as well as in medical applications for conditions like muscle spasms, migraines, and excessive sweating.
