Is Mehron metallic powder just mica powder ?

No, it is a very fine aluminum powder that you can mix with oil for a very shiny look, though it never dries, or you can use a mixing liquid that does dry but it makes more of a matte finish.

Thanks bobbyqp.

Would mica powder mixed with oil be safe to use all over the body as per Mehron ?

(Just that Mehron is more expensive than mica powder - trying to get a cheaper alternative to Mehron)

I have used mica only once. I assume it is safe because I bought a name brand. Perhaps Nye. Anyway, I did not like the mica because it does not have the shine the Mehron has, unless there is some way I am not aware off to makek mica shiny.
