Which filler gives the most natural lip augmentation results - Juvederm or Restylane?

Hi there, browneyed. Different
fillers yield different results on different patients. JUVÉDERM, Restylane, and
Restylane's cousin, Perlane, are all hyaluronic acid (HA)-based fillers that
may be used in the lips. Although they have the same active ingredient, there
are subtle differences between them, mostly related to the sizes of their HA
particles. Your doctor will evaluate your lips and make a sound recommendation
for you based on your anatomy. Ultimately based on the product selected, the
treatment site identified, the quantity of product used, and the skilled and
artistic eye of your injector, you should receive a natural-looking and
beautiful result. Be sure to seek out a board-certified dermatologist or
plastic surgeon who has plenty of experience with lip augmentation. For a truly
natural result, don't rule out fat grafting, either. This procedure uses your
own fat (typically taken from somewhere such as your abdomen or thigh) and
transplants it to the lips. Invest in a consultation to obtain a plan and
assess the talent of your injector before getting started. Best of luck!

It's not as much about the product as about the artistry and experience of the injector.  I prefer Juvederm in the lips and feel it lasts longer with a very natural correction (Ultra plus when I am looking for more volume and Ultra for just definition)  but what is really essential is that you seek out an experienced injector who can discuss their vision for your lips.
