I had one syringe of Juvederm done. I feel like I can't notice much of a difference (Photo)

The amount of filler in one syringe of Juvederm is equivalent to 1/5 of a teaspoon (5 syringes = 1 teaspoon!).  Lip augmentation can be affected by not only the volume injected but also the placement of the product.  It can take up to 2 weeks to see your final results from lip injections to allow any swelling or bruising to dissipate.  Follow up with your injector at 2 weeks for an evaluation and to discuss your current results, the look you desire to achieve and realistic expectations.  You can then determine if more filler is needed to enhance your lips to the desired look.  

It takes up to 2 weeks for final results. Additional filler may be needed to get your desired results. I recommend following up with your injector. Best, Dr. Emer

Dear tinavides113088,I typically use Juvederm for my lip sculpting. There are two main focuses of lip injections, adding volume and actually sculpting the shape. Both involve injecting the filler in different areas of the lips and patterns. You can always add more filler in order to achieve the desired look.
I would recommend finding a plastic surgeon to perform you lip injections. Most of my patients have results that last at least 6 months.Daniel Barrett, MD

The amount of filler needed will depend on your anatomy and treatment goals.  The wonderful thing about fillers is that you can go slowly and build up to the look you desire.  I recommend waiting two weeks from the first injection before having a second so that you can judge based on your final results.

It takes 1-2 weeks for final results, which can be gradual. I would wait a full 2 weeks before assessing results. Additional filler may be needed to get the results you want. Hope this helps.
