Most people are familiar with traditional dermal fillers such as Juvederm and Restylane which use hyaluronic gel to add volume to the face and smooth out lines and wrinkles. Sculptra is also a type of dermal filler, but it works by stimunlating collagen production using Poly-L-Lactic Acid (PLLA), a natural substance in the human body. Sculptra stimulates collagen production over time, gradually improving volume-loss and wrinkles. Hyaluronic gel and PLLA fillers both work well to provide natural, long-lasting results. There are differences between the two: Sculptra lasts up to two years, while hyalurnoic gel fillers tend to last for 6-12 months. Sculptra is a gradual treatment that requires multiple sessions to achiieve best results. Hyaluronic gel fillers may only require a single session. Sculptra costs more per treatment session (but gives longer-lasting results).
