Dermal fillers are gel-like substances that are injected beneath the skin to restore lost volume, smooth lines, and soften creases, or enhance facial contours. They are commonly used to plump up wrinkles and smooth lines on the face, and there are several types of dermal fillers available. These fillers are typically injected in areas around the eyes, mouth, and nose, and the results are usually seen right away, lasting for months or even years, depending on the type of filler and the location. Dermal fillers are a common cosmetic procedure, with more than 3 million people in the United States choosing to get them every year. The types of dermal fillers include hyaluronic acid, calcium hydroxylapatite, fat grafting, poly-L-lactic acid, and polyalkylimide, each with varying longevity and softness. The procedure is generally an outpatient one, taking less than half an hour, and recovery time is minimal. It is important to work with a licensed healthcare provider who is experienced in injecting dermal fillers and knowledgeable about the risks and benefits before receiving treatment.
