Thank you for posting your photos with your question. There are 2 types of Juviderm: Ultra, which is lighter and Ultra Plus, which is more viscous. A 1 cc syringe of Juviderm, which is a Hyaluronic Acid filler, is sufficient to augment your lips. I recommend that you bring a photograph of a women's lips, that you like, to your consultation with a Board Certified Plastic Surgeon who is experienced with lip injections. This will give the injector a very good idea of the size and shape of the lips that you desire and which Juviderm to use. When in doubt, use the Juviderm Ultra, because it is softer and you can always add more. Best wishes, Dr. Richard Swift
