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, smooth lines, and restore volume in the face. There are several types of dermal fillers, including those made with hyaluronic acid, calcium hydroxylapatite, and polyalkylimide. These fillers are injected under the skin to create a smoother or fuller appearance, or both. The results of dermal filler injections are noticeable right away and can last for months or years. Dermal fillers are a common cosmetic procedure, with more than 3 million people in the United States choosing to get them every year. Its 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.
