Injectable filler (injectable cosmetic filler, injectable facial filler) is a soft tissue filler injected into the skin at different depths to help fill in facial wrinkles, provide facial volume, and augment facial features: 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, and 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. Fillers are not approved for certain parts of the body where they can be unsafe, including the penis.
