Chinese face massager thingy. What will it do for me?

My mother got this for me as a Christmas present. It basically looks like a miniature paint roller, but made of jade (or a similar green stone). The lady in the shop told my mother that you put a bit of cream of cream on it and roll it on your face. I have been doing it and it feels quite nice and after a while it turns my cheeks pink the way I usually get after some alcohol. So I’m quite happy with it as it is.

I’m just wondering if achieving the “blush” look without blusher is the reason people use it or whether the massaging of the face has some kind other benefit? Good for the skin? Tension relief? I don’t know. Lettering on box is in Chinese characters which I can’t read. Does anyone know more about these nifty little things?

Sounds like you’re stimulating circulation without rubbing/abrading the skin surface; it probably doesn’t have a lot of long-term effect, but you should probably not press too hard, in case you damage a blood vessel near the skin surface.
