It’s a standard query: What is the distinction between rhassoul clay and the opposite well-liked clays on the market—specifically, bentonite and kaolin clays? Effectively, most of the distinctions need to do with the supply and make-up of the clay itself: “Many of the variations between the assorted clays depends upon the situation it’s derived, composition, and particle dimension,” says Robinson. “This variation can have an effect on the colour and mineral content material.” (Learn: Since Rhassoul clay comes from Morocco, it has a barely completely different mineral content material and hint parts than bentonite and kaolin, which stem from France and China, respectively.) 

And whereas all three choices can successfully draw oil and impurities from the pores and skin and scalp, they accomplish that with various levels of absorption. Bentonite clay is essentially the most absorbent of the trio, making it ultimate for shiny and acne-prone pores and skin; rhassoul clay, with its honeycomb construction, is a cheerful center floor—absorbent, however not too stripping (these with drier pores and skin could discover that bentonite clay attracts an excessive amount of moisture). Kaolin clay has the least absorption, Shamban notes, because the construction is fenestrated; that’s why kaolin clay “is among the mildest choices” to slather on pores and skin, says board-certified dermatologist Lauren E. Adams, M.D. about clay masks.
