Wrinkles and fine lines on the face are often the result of repeated muscle contractions. Over time, these contractions can cause creases and lines to form, particularly around the eyes (crow's feet), between the eyebrows (frown lines), and on the forehead. Botox can decrease these lines.

Botox contains a purified form of botulinum toxin, a naturally occurring protein produced by the bacterium Clostridium botulinum. When injected, his toxin has the unique ability to block signals from nerves to muscles, essentially preventing those muscles from contracting.

When Botox is injected into specific facial muscles, it temporarily inhibits their ability to contract. As a result, the overlying skin becomes smoother, and existing wrinkles and lines appear less prominent. This effect typically lasts for several months, after which the muscles gradually regain their normal function.
