I bought this after reading several reviews that it is as effective as the original Dr. M. Having used both I can assert this product is NOT nearly as effective. I still had some of the original Dr. M. and did a half and half comparison and it was immediately clear. This exfoliate "pills" like the original but not nearly to the degree and when washed away the half I used the leftover Dr. M. was clean of dead skin and showed clear pores. The other half? Not so much. I'll be going back to the original.
