Injectable filler

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.

In the US, fillers are approved as medical devices by the Food and Drug Administration (FDA) and the injection is prescribed and performed by a health care provider. In Europe and the UK, fillers are non-prescription medical devices that can be injected by anyone licensed to do so by the respective medical authorities. They require a CE mark, which regulates adherence to production standards, but does not require any demonstration of medical efficacy. As a result, there are over 140 injectable fillers in the UK/European market and only six approved for use in the US.

Fillers are made of sugar molecules or 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.

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:

Risks of an improperly performed dermal filler procedure commonly include bruising, redness, pain or itching. Less commonly, there may be infections or allergic reactions, which may cause scarring and lumps that may require surgical correction.
