Botox contains purified bacteria that freeze muscles. In doing so, Botox can help minimize the appearance of lines and wrinkles caused by facial expressions. These are typically found in the upper face, such as the forehead and around the eyes.
Dermal fillers use hyaluronic acid and similar substances to “fill in” or plump areas that have lost volume and smoothness. This includes wrinkles around the mouth, thin lips, and cheeks that have lost fullness. They may also be used on forehead wrinkles, scars, and other areas that need extra volume for a smoother look.
Botox results last 3 to 4 months. Dermal filler results vary, depending on which filler is used.
