As with any injectable filler, you may experience temporary pain, swelling and reddening at the treatment site. These side effects are usually gone within a few days. Occasionally, there is transient bruising that typically disappears within 7 days. Less common side effects include rash and itching more than 48 hours after treatment, persistent swelling or redness, and increased sensitivity at injection sites. Two other rare potential side effects of all fillers may be lumps and granulomas, both of which may be treated by your Licensed Provider. Be sure to call your Licensed Provider immediately if you notice any unusual skin reactions around the treatment area.
