Can under eye fillers like Restylane last two years?

I don't quote 2 years, but it is possible they can last that long. In most patients, these products last about 1 year.Best wishes, Dr. ALDO 

The short answer is yes, Restylane can last for 2 years in the under eye area but no, the results do not usually last this long.Generally the results of under-eye fillers last about a year but the hyaluronic acid gel is present for much longer. So you should not necessarily expect to see smooth under-eyes for that full period of time. 

I do think that fillers under the eyes last longer than same filler would last in other areas but length depends on which filler and on patient. I would tell you that if you were lucky it COULD last up to two years but more commonly I see these last a year or maybe year and half. Less commonly, I see these last six months. The good news is that you don't usually need a lot of product under the eyes so it is nit a huge investment. If you want this, give it a try.
