Botox™, aka onabotulinum toxin A.

It is the number one choice for safely and effectively treating wrinkles. Botox is injected into targeted muscles, relaxing the muscle and thus temporarily smoothing out the fine wrinkles and deeper borrows between the brows, near the eyes, and on the forehead. Generally, the results last between 3 to 4 months.
