What is the best lip filler or procedure for lifting the upper lip and defining of Cupid bow? (Photos)

There isn't a best filler for lip augmentation. Many fillers, however, are made of the material hyaluronic acid, which is normally found in the skin. These "lipstick in a syringe" treatments last approximately six months. First time patients often choose Juvederm or Restylane. Each plastic surgery office might have their own preference.Best,Dr. Chaboki

Hi @jessicagriffin! Restylane Kysse works beautifully. I recommend seeking treatments from expert injectors who have the skill and experience to precisely inject fillers into treatment areas and avoid risks and complications. Best of luck, Dr. Nima!

Lately it seems as though there are new fillers being FDA approved every day.  In the photos that you have provided the best choice for lip filler would be Juvederm Ultra.  You appear to be young and will need a filler that can provide volume to your lips.  Volbella is excellent for defining lips and filling in vertical lines around the lips but will not create the fullness you are seeking. Restylane Defyne, which is newer, can also plump and define your lips appropriately.  

my choice of treatment is a combination of Botox and filler. sometimes i do both the same day. Im not sure if you will need both without examining you in person. but the problem is not that complicated. it can be significantly improved the way you see fit

Restylane Silk,  Volubella are a few of the hyaluronic acid based filler choices available for augmenting the lips.

I use Restylane, but Juvederm is probably just as good.  The hyaluronic acid fillers, ie Restylane or Juvedem, are most frequently used for lip augmentation. These are nice because if there is an issue, they can be dissolved with a simple enzyme injection.  A tiny bit of Botox can sometimes help with give a bit of "pout" to the upper lip.  

Thank you for your question. 
There are many great products for defining Cupid's bow and plumping upper lip. Juvederm Volbella is the newest FDA approved filler for lip lines.  It does a great job at softening lip lines without the bulky or puffy appearance with a one year longevity. For restoring lip volume Juvederm Ultra or restylane would be good choices. 
Please consult a local board certified facial plastic surgeon for more information and a comprehensive consultation 

A Hyaluronic Acid(HA) based filler such as from the Juvederm or Restylane family of fillers generally work extremely well if performed by an experienced and expert physician injector. In some cases, botox may be also be helpful. Consult in person with an experienced and expert physician injector to understand your options.

We recommend a Hyaluronic Acid(HA) based filler such as Juvederm or Restylane.  The advantage of these is that they are the proper consistency but the real advantage of HA fillers is that they can easily be reversed should you not be happy with the outcome.  Sometimes we will also use Botox to help achieve the desired effect.  The most important aspect is to see a a qualified provider in your area.

Hi!  You would do very well with Belotero, Restylane or Juvederm.  This would really add to your lips. These products last 6 to 8 months.  Make sure you consult with an experienced doctor.
