Botox is good for any area of your face that is affected by wrinkles or fine lines as the result of changes to our skin due to aging. Botox can also be used on other areas of your body to treat other ailments not related to aging such as migraines. On the face, Botox is used on several areas where wrinkles and fine lines appear over time due to the muscles of the face contracting repeatedly for actions such as frowning, smiling and laughing. These repeated actions cause the skin to crinkle, which over time creates horizontal wrinkles on the forehead, vertical wrinkles between the eyebrows and on the top of the nose, fine lines around the outer corners of the eyes and around the lips, and wrinkles on the chin. Botox works by relaxing the nerve endings, which prevents the muscles from being able to contract and crease the skin.
