How many CCs would I need to add to make my lips fuller like Kylie Jenner? (Photo)

For lip augmentation, the best is to go slow, you may need just 1cc of hyaluronic acid based filler, to get the size that you are looking for. After the injections you need to wait for about 4 weeks and if you still want a little more volume, then you may have another 1cc. You just need some time to adjust to new size on your lips before deciding if you want more or just 1cc is enough.

Volume is just one component of beautiful lips.  Shape and distance from nose to lip are other important pieces to it, as well as "advaced" techniques in lipstick application (in the case of the KJ photo). While it is impossible to make one's lips (or nose, or face, etc.) look exactly like someone elses, I do encourage men and women to bring in photos of what they like.  It looks like you have pretty good volume, so if you never had lip augmentation before I would consider starting with 1 syringe of Restylane or Juvederm (about 1 cc).  More can always be added.  If the product is placed properly, it can curl your lips and give them a sexier pout that KJ demonstrates in her photo.

they would all comment that they're already quite full, plump and perfect without any further modification...really don't think it would be a good idea to mess with success...if you enhance your lips from the current appearance, they will be out of place on your face..get some friend's opinion before you proceed...

From the photos attached, your lips are fairly full.  To accomplish your goal, we would use 1 cc of Juvederm to your upper lip.  Hope this helps.
