No, Botox and injectable dermal fillers are different substances that function in different ways. Botox is a neurotoxin protein that temporarily freezes muscles to smooth out fine lines and wrinkles on the skin's surface. Dermal fillers-- usually composed of hyaluronic acid-- restore volume to areas of the face that have lost fullness. Fillers visibly plump up areas that have sunken and thinned over time and can be combined with Botox treatment for enhanced aesthetic results.
