? re benefits of clays

[Guest guest]

I've searched the archives (back only a year, I admit)

and googled and did an emedicine search for this before coming to you guys--

but can anyone point me to research and findings on any proven benefits to

using clays and muds in skincare?

I have Bentonite and French green clays--and can't say that i care for them

much in masks-- I think they are awfully drying--I use the green clay as a

colorant in soap.

But I read these raves about Dead sea mud and argiletz clay--is there any

truth to claims of them as purifiers?

thanks, Zoe
