Thank you for your question. We do filler incrementally over time as that tends to give the most natural results, so yes it should help to add filler every 2 weeks or so until you are happy. Regards, Dr. Matt Elias
Two weeks is a good time to get more filler if you feel you need it. Swelling resides after a few days, so when the swelling is gone and you still feel like you want more, I would consult your injectibles expert. Best of luck!
Lip Fillers Long Term, Use Cannulas and a Conservative approach
It is best to do little bits over time to get a result that is natural without swelling. you may need more than 1-2 syringes depending on your starting point and the swelling goes down 1-2 weeks after injections. Best, Dr. Emer.
Lip Fillers and Re-treatment
There is often swelling from Restylane that goes down after a week or two. If you need more filler than two weeks is the perfect time to have more product injected. Best, Dr. Green
