Hyaluronic acid fillers can give you a more youthful look for a fraction of what a traditional facelift costs. Most will fill lines and wrinkles in less than 30 minutes with results that can last from 4 months to more than a year, depending on the type and brand of fillers.

It is used as “volumizers,” plumping and lifting cheeks, jawlines, and temples; filling out thin lips, and plumping sagging hands.

How long the results last varies from several months to over a year or two. Some research shows that repeated injections may help stimulate the body’s own natural production of collagen. That will help reduce the number of lines and wrinkles. There is also some evidence that less filler is needed over time to achieve the same look.

Side effects are rare but can include redness, swelling, and bruising at the injection site. The filler may also show up under the skin as tiny bumps. This is a problem that often improves over time.
