I add mine into the fridge. I can't say it's magic or anything but if you use facial tools I do really like this one. It glides easy and fits well in the hand. ONE THING- if you want cold put it in the FREEZER for some time before use it doesn't hold it's coldness for long. It's nice and solid. I would say the price is what got me. But it is Jade so.
The product itself is beautiful, and by the way it feels, you can tell that it is well made. It feels amazing on the skin and reduced my dark circles in the matter of one night!
I've been doing some facial massage techniques for a little while but this tool makes it SO much easier. I keep it in the fridge so it's a little cool!
