Injectable hyaluronic acid fillers, unlike Botox injections that relax the muscle under a wrinkle, fill the line, crease, or area with one of several different substances. As a result, trouble spots nearly disappear.
Cosmetic fillers can also be used as "volumizers," plumping and lifting cheeks, chins, jawlines, and temples as well as filling out thin lips.
The treatment is fast and easy and the results can last anywhere from 4 months to a year.
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.
