I had restylane injected in to the tear troughs to help my chronic dark circles.
Even through the numbing cream it did smart quite a bit, and the sounds! There were crunching sounds that weren't so pleasant, but it was all worth it to wake up in the morning and not have a half hour spackle job of applying layers of primer and concealer and setting powders. I only required 1cc, and she didn't use all of it, so we put it in the marionette lines (running from nose to mouth).
I had a little beading the first couple of days, which I hear is a common complaint, but the practitioner had me press on it for 15 seconds several times through the day and it's gone.
I LOVE not having dark circles! It is one of the greatest luxuries. I highly recommend this procedure. I also recommend researching your practitioner or MD.
