Everyone is different
The fillers that you have mentioned sometimes have unpredictable results. Some patients get so much swelling from one syringe, they would never think about doing more. Others like you do not see the lasting results with small volumes. I think you are independently learning that to meet your expectations, it will require a lot more volume. You are still getting the proper fillers, so it's just a matter of putting in more. Best of luck
Juvederm and Lips
Lips are a great area to inject to enhance your features. The amount of Juvederm depends on how thin your lips are to start. It will take at least two syringes to have lips that full. For the best cosmetic results please consult a board certified dermatologist with experience with Juvederm.
Amount of Juvederm/Restylane to achieve lip augmentation results
You seem to have a good understanding of your goals/expectations. We do not know at what point you are starting so we can not properly guide you on the number of syringes to achieve your goals. Consult with 3 experienced and expert physician injectors to understand your options. As a new patient, the inclination of many top injectors is to inject some and observe the results in you. More can always be added. If you do not have the patience for this process, clearly define your expectation during the consultation process.
Juvederm & Restylane
Both of these are HA fillers with incredible safety records. They are a wonderful choice for lip augmentation. that said, they don't last that long and are not of great value, in my opinion. There are other options for long lasting lip augmentation, including lip implants and Silikon 1000.
It sounds like you haven't found the right doctor for you. The lips in the photo are awesome. Lip augmentation can be very rewarding. Fillers can augment what you have been given genetically. The key is to create a natural fuller version of your own lip. One of the down falls with fillers is trying to do too much with one syringe. It's like trying to paint an entire house with one can of paint. I think the key for you would be to find an expert injector who you can trust and is a good listener. They can advise you as to what reasonable expectations are. Good Luck!
Juvederm & Restylane don't do much--What amount will it take?
A photo showing your starting point would be helpful in providing you with an estimate of how much Juvederm or Restylane will be required to create fuller lips seen in the photo you've posted. If you think you're ready for 4 syringes of filler, don't be disappointed if it takes fewer than 4 syringes to reach your goal. Even thin lips can achieve significant fullness with 2 to 3 syringes. Thank you for sharing your question. Best wishes.
How many syringes to get these lips
Well, it depends on what you are starting with. You posted a photo of what you want them to look like "after" but I have no idea what you are starting with, or even if you have the same general shape of the lips. So, if you can post a pre-photo, that would sure help us give you a *realistic* answer on how many syringes you need....

There are many reasons why a doctor might have told you to go with 1 syringe and wait for the results.
