How do dermal fillers work?
The active ingredient in Restylane is derived from hyaluronic acid, which is a natural sugar found in the skin. Its function in the skin is to maintain volume and pliability. The unique property of this acid is its ability to bind with water molecules up to 1000 times its original size, making it an excellent choice for a filler. Because it can bind with water, it is extremely safe when eliminated with regular body waste over time.
