I got 1cc of Juvederm for my lips 4 days ago and my lips are back to normal?

Thank you for sharing your question and photographs.  Due to the thin nature of the lip tissues you can experience a fair amount of soft tissue swelling that can leave you with an initial result that is larger than what your long-term gains will be.  In these instances additional filler placement will help get you to the previous "swollen" look.  Additionally, when women first have fillers placed some of the initial product placement will only stretch out the lips and not necessarily add substantial volume or projection.  The following injections should make a more dramatic difference in volume.  Hope this helps.

Your lips definitely look plumper in your after pictures. You won't really have your final results until 2 weeks after your injections. I recommend waiting and then if you're unhappy you can have a touch up of more filler. It may be that an alternative technique would give you better results. Implants and fat are also options for a more permanent result. Best, Dr. Emer

It is best to wait two full weeks before assessing your results.  If at that time you are still unhappy, you can return to your injector for more product.  It may be that the look you desire requires more than 1cc of filler.  Good luck.
