Is Belotero affective after using Juvederm Volift since 2018? Which would provide the best results?

Volbella, Restylane, and Juvederm are good fillers to use to create a symmetrical lip. NovaThreads can also be used to improve lift and shape. Implants or fat are alternatives. Technique will be important here, so you'll want to see someone meticulous. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Dear Rose_T,
I perform a lot of lip injections with fillers such as juvederm and it works great. Many times I need to put more in one side than the other to attempt to even out the vermillion border (The red line of the lip). This helps provide more symmetry at times.For patients looking for a more long lasting result, I recommend fat grafting. That is, using your own bodies fat to make your lips naturally look more shapely. The bonus is that the results last many many years.
In general, I avoid using permanent prosthesis because I find that the lips are such dynamic and sensitive structures, the end result is not natural.

There are a variety of different fillers that can be injected nicely & safely into the lips, the most important issue being training & knowledge of anatomy, as well as product selection, depth of injection, and quantity injected. Not sure why they are trying to switch you, other than if you were having an issue with Volift such as say insufficient duration. Belotero is fine, not necessarily superior, and certainly far fewer years of experience with it on the market.
