Why Are Restylane Injections (Undereye Hollows) So Expensive?

Fees vary.  My fee is lower and I think that you might want to comparison shop to verify that other skilled injectors in your area are in the same price range.  All of the cosmoceuticals and injectibles cost plenty for the doctor to purchase from the manufacturer and, actually, the supplement for his time and expertise isn't terribly high.  I personally find the notion of 4 syringes in a single sitting for the lower eyelids to be high.  You haven't posted a photograph but generally I use 1-2 syringes for this area, so this is another issue that you should resolve by additional consultations.

The fee for restylane will vary around the country.  There are several ways to treat the lower lid region: sometimes surgical and sometimes filler, and sometimes a combination.  Fat grafting ti also an alternative.
