Botox cosmetic is a prescription injectable medication used to temporarily reduce and improve the appearance of moderate to severe wrinkles on the face and neck. Improvement is seen as botox temporarily weakens or blocks muscle contraction, reducing appearance of wrinkles and fine lines. Aside from the upper face,  Botox is used therapeutically to help reduce the pain associated with Bruxism or teeth grinding/clenching when injected into the masseter muscle.
