Juvaderm treatment, for the lips and frown lines, works very well and with little down time. Side effects from Juvaderm injections will vary greatly from patient to patient. Different skin types, different areas, even different regularly taken medications, can affect the amount of bruising and swelling that appears. There may be some pain at the injection site, however, as well as different amounts of swelling and bruising. These side effects will disappear on their own, in roughly 8-10 days. In just a couple days, the area treated should be looking much better and you should really be noticing some fabulous results. You will probably want to take the rest of the day off, after a treatment of Juvederm, let yourself get comfortable with any bruising (make-up and concealer can do wonders!) or swelling that initially appears.
