Should I get 1ml or 2ml Juvederm lip fillers?

I advise my patients to start with 1 ml of filler in the lips and wait 10-14 days to see how the lips look after the swelling resolves and then make a decision as to whether to get a second 1ml syringe. Remember there is no hurry.  Discuss your concerns with your injector and describe the look you desire.

While this will depend on your desired results, I recommend starting with 1 ml. I prefer to use a micro cannula to inject the lips to prevent swelling and/or bruising. Look for a cosmetic dermatologist or plastic surgeon who is an expert in fillers to discuss your desired results and concerns. 
I hope this helps.

I would most definitely start with 1 ml of a filler such as juvederm or Restylane. Most of the filler should go to your upper lip since your lower lip appears to be quite full. Should you decide to have more product, you can always do so 1 to 2 weeks after the initial treatment.
