I think facial massage can do wonders for your lymphatic drainage etc.
I don't see what difference a fake Jade stone (serpentine by a fancy chinese name) is going to make though.
You could pop into any new age store and get a nice bit of quartz to roll around your face should you feel the need. Couple of quid- will do the same job.
I am not WOO at all. But I do have a couple of slices of agate that tend to be nice and cool. I stick them on my eyes and it helps relieve puffy bags. I could use cold teaspoons- the agate itself makes no difference.
