Botox and dermal fillers are cosmetic treatments given through injections, usually in a doctor’s office. They are minimally invasive, meaning they do not involve surgery. That is where their similarities end, however.

Botox: This freezes muscles to stop creases and wrinkles caused by facial expressions. 
Dermal fillers: These use hyaluronic acid and similar substances to "fill in" or plump areas that have lost volume and smoothness. Botox results last 3 to 4 months.
