Can Anyone Recommend Tear Trough Expert in Ireland or England?

The last few years, I have lost facial fat due to aging and now have big dark hollows under my eyes. I would like to get Restylane to plump it up, but after reading all the horror stories am trying to be extremely careful about who I go to.

Does anyone know if anyone in Ireland is good at this? Or failing that, an expert somewhere in England where it's easy to fly to (like Manchester)?
