is it safe to mix juvederm ultra with volift/vollure?

Both fillers are safe to inject at an interval after the other - both being hyaluronic acid will not interact. It's usually on the the different fillers containing collagen that arent safe to interact with HA fillers unless there has been 3 years since the last collagen injection.

It is fine to have both of these fillers used in the same area.  There should be no issues from injecting Juvederm Ultra even if some Volift is still present in the lips.  Be sure to see an expert injector near you .

It is safe to use different hyaluronic acid fillers in the same location.  Different products have different properties, so using one filler to give structure and another to give volume works well.

thankyou for your question.You do not need to worry about overlapping these products. if you want fuller lips its Ultra that is best . The volift only contours its not a volumiser. I only use volift in lips for women who would like the area to look rejuvenated. Anyone that wants volume Ultra is best. I don't look at duration but at the best product for the job. Hope this helps

Hello,
Yes, it is absolutely safe to have both Juvederm Ultra and Vollure in the lips at the same time. They are both HA fillers. 
Best of luck!

Mixing Juvederm Ultra, Vollure, and Volbella in the lip is not a problem. In fact, I do this very frequently to obtain the desired results. We do not have Volift, but it sounds similar to Vollure. Personally, I really like Ultra in the lips.
