Most people seem to have swelling in the lips after hyaluronic acid injection for up to five days after the hyaluronic acid filler, but occasionally I have seen someone with persistent swelling for two weeks. Bottom line, I would say be patient, and give it a week or two unless there is pain and redness associated with the swelling which are signs of infection, then you would want to report that to your physician.
Its difficult to say what is swelling and what is product as everyone is different and some swell more then others. You need to let the product settle and swelling to subside for 2 weeks to see the final results. Best of luck
Mnl1985, your lips will get a little smaller than they are now. Swelling lasts for up to a week, occasionally a little bit still in the second week.
Keep it natural, you will be much happier in the long run. If you think it is not augmented enough after a week, I advise you to live with it for a month or two before deciding to have more filler injected. .
