How does Botox work to reduce the appearance of wrinkles?

Botox works by temporarily blocking the nerve signals to the muscles where it is injected, preventing them from contracting. This relaxation of the muscles smooths out the overlying skin, reducing the appearance of existing wrinkles and preventing new ones from forming. It is particularly effective for dynamic wrinkles that appear as a result of facial expressions, such as forehead lines, crow’s feet, and frown lines. The treatment is quick, with minimal discomfort, and results can be seen within a few days, lasting typically for 3 to 6 months.
