Why do my lip fillers not last on me? Juvederm - had around 3ml spread over 4/5 months

It may be that a different filler like Restylane may give you longer lasting results. I recommend following up with your injector about your concerns. Hope this helps.

Thank you for your question. Results vary from patient to patient. It could be that more product is needed for results that last longer, or perhaps you may benefit from a different product altogether. Ultimately, results cannot be guaranteed for every patient. 

Lip injections are an art and a science. I would definitely recommend you consult an expert and try a different hyaluronic filler which has a higher G-prime like Restylane Lyft.  There are many different choices of fillers and it would be most helpful if you would re-post the question with before and after photos.
