Botox is a great product when used correctly. The most common areas to have Botox treatments are in the forehead, between the eyes and lateral to the eyes. Botox is typically helpful to treat lines caused by movement. Your muscles cause folds in the skin that lead to wrinkles.
Botox is not a filler and is not the first choice in treating other areas in the face that need replacement of the volume that many patients lose over time as they age. Most patients need a combination of Botox and fillers to reach their aesthetic goals. Botox can be used in other areas besides just the forehead but that is dependent on the individual needs of each patient.
This is why it is important to have a consultation with a board certified plastic surgeon. They can evaluate you and discuss your treatment options that are going to help you achieve your aesthetic goals. There are so many options to give you a more youthful and rejuvenated appearance.
