What Are Dermal Fillers, and How Are They Used?
In general, injectable dermal fillers are intended to help fill in wrinkles and give a smoother appearance. They are generally injected into the skin with a needle and are regulated by the FDA as medical devices.
Temporary fillers include the following materials:
- Collagen injections, made of highly purified cow or human collagen.
- Hyaluronic acid gel, a protective lubricating gel, produced naturally by the body.
- Calcium hydroxylapatite, a mineral and a major component of bone.
- Poly-L-lactic acid (PLLA), a biodegradable, biocompatible, synthetic material.
