Dermal fillers are a naturally-derived or synthetic material that is directly injected into skin with the purpose of plumping that area to the point where the wrinkle, depression, or fold is gone. Depending on the type of filler, the effects can last anywhere from six months to two years; for semi-permanent or permanent fillers, the effects can last up to five years, and there are reports of even longer-lasting results.
Don’t confuse dermal fillers with Botox. Although both procedures involve injections, Botox is most often injected around the forehead and wrinkles around the eyes (crow’s feet) to stop muscle movement that results in wrinkles. It has nothing to do with the plumping smoothing effect dermal fillers have.
Because they work in different manners, many people elect to get both Botox and dermal fillers—the combination can produce a remarkably younger-looking face.
