Injectable filler (injectable cosmetic filler, injectable facial filler) is a soft tissue filler injected into the skin to help fill in facial wrinkles, restoring a smoother appearance. Most of these wrinkle fillers are temporary because they are eventually absorbed by the body. Some people may need more than one injection to achieve the wrinkle-smoothing effect. The effect lasts for about six months or longer. Successful results depend on health of the skin, skill of the health care provider, type of filler used.
HOW DO FILLERS WORK?
Dermal fillers, also known as “injectables” or “soft-tissue fillers,” do just what their name suggests: they fill in the area under the skin. Some fillers are natural and some are synthetic, but they all work to improve the appearance of aging skin in the following ways:
- Filling in wrinkles, fine lines and deep creases
- Improving other imperfections like scars
- Filling out thin or wrinkled lips
- Plumping up cheeks
- Contouring the jaw line and other areas of the face
WHAT DO FILLERS CONSIST OF?
Fillers are composed of hyaluronic acids, collagens, which may come from pigs, cows, cadavers, or may be generated in a laboratory, and biosynthetic polymers are used as well, including calcium hydroxylapatite, polycaprolactone, polymethylmethacrylate, and polylactic acid.
