Over the last 4 years, I have had two Restylane treatments, neither of which turned out well. Very lumpy and obvious-looking for up to 18 months.
What I learned is that the nurse/doctor who injects the product is the crucial part. A week and a half ago I had Juvederm injected into several areas on my face. I finally look like the "after" pictures in the hyaluronic manufactures' adverisements -smooth, and completely natural appearance.
Juvederm, from what I understand, is of a smoother consistency, and is also FDA approved to last up to one year. The FDA approved Restylane for just 6 months. Restylane lasts longer when improperly injected (too close to the surface) - that is why mine lasted so long and looked so bad. I am so happy with the Juvederm!
