Can I use a lip plumper like Candy Lipz after Juvederm lip injections?

Thank you for sharing your excellent question.  I would STRONGLY recommend not using suction cup devices like Candy Lipz to further increase your lip volume.  At best these devices are ineffective and difficult to control, but at worst can cause tissue damage and bruising to your lips.  If you would like additional volume have a thicker hyaluronic acid filler, like Juvederm Ultra Plus placed by a board certified plastic surgeon.   Best wishes.

I don't recommend using these types of devices. I recommend following up with your injector. A touch-up of filler may give you the results you want. These fillers, (Restylane, Volbella, Juvederm) are good to create a symmetrical and full lip. Implants or fat are alternative options. See an expert. Best, Dr. Emer

In most cases, the use of Candy Lipz post treatment is not advised. Consult with your injector as he or she knows the scope of the treatment and the specifics about you. 

Post lip fillers, you need to give your lips time to heal completely before using any lip plumping products. 2 - 3 weeks should be sufficient. Always get your surgeons approval before using any products. Regards.

I would go ahead and do what you would like to your lips. You are well out from the immediate swelling stage and there is nothing you can do at this point that will affect the filler.
