If you have a history of Bell's palsy and are thinking of getting BOTOX Cosmetic injections for wrinkles, you should see a physician with a lot of experience with these injections. Oftentimes, the patient will have excessive wrinkling and muscle movement on the unaffected side, and BOTOX Cosmetic treats this wonderfully. If an area is drooping it may not actually lift it, but weakening of the stronger side could make you look more symmetrical. If an area of the affected side is contracting in a spastic manner, BOTOX Cosmetic could also improve that as well. It is a safe treatment option as BOTOX Cosmetic has been around for more than 25 years.
