Fillers and Botox are both wrinkle-reducing injectables. However, there is a notable difference in how they work.
Fillers instantly add volume to plump up the treated area. They are commonly used for folds and creases around the nose, mouth and chin that result from the breakdown of collagen.
Botox temporarily relaxes targeted facial muscles to smooth creases caused by repeated facial expressions. These wrinkles naturally occur around the corners of the eyes, on the forehead and in between the eyebrows.
