What Are Facial Fillers?


Dermal facial fillers, also known as injectables, are used to volumize the skin and promote the production of collagen. Loss of collagen as we age results in wrinkles in the skin, typically around the eyes, mouth and forehead, and contributes to making skin look older.

Dermal fillers replace lost volume and smooth away moderate to severe facial wrinkles and folds. Unlike a face-lift, which pulls the skin taut, volumizing plumps up the skin, restoring youthful contours to the face and resulting in a more natural look.

According to Rhoda Narins, MD, professor of dermatology at NYU Medical Center in New York City, “What’s really significant is that we can now use these fillers to volumize skin anywhere on the face, so we can really sculpt a lifted, youthful look without surgery.”

Studies conducted by Frank Wang, MD, at the University of Michigan Medical School found that fillers containing hyaluronic acid (such as Restylane) led to “robust collagen production” while also interfering with collagen breakdown. So not only do you get a filling effect, but you also have an actual increase in the production of collagen.

Currently, most fillers last up to one year or longer, and the track record on safety is generally good (approved wrinkle injections have been used in Europe for several years). Side effects are mild and typically limited to redness or swelling at the site of injection.
