If you get a facial in china there should be nothing to worry about. The only suggestion I will give you is to stick to a more upscale parlor. I've seen some at some raunchy places that are in wide view to the public. One in particular at 77th street. But you shouldn't worry about facials here in China they are safe.

Since I do not use any of them, I am not really qualified to give you a good answer, but my GF is always using them, all kinds of them, and she is still alive.  Also, you do not hear in the news anyone dead or with the face burned out after visiting the spas.

And you can always instruct them not to use anything that has skin whiteners on you if that is your wish.

My GF loves to spend one day at the local Spa getting "pampered with a hot tub, a good body massage, skin cleanser and a hairdo and nail job.  And here is not that expensive.

I want to make a joke about facials and skin whiteners, but I won't.

If you're really worried about it, take your own product and just enjoy the massage/pamper part of it.

i think it's not safe to get a facil in china.
