Skin feels so soft!
I actually love this stuff it makes my skin feel so smooth and soft after I use it! I don’t see a difference between the two they both work equally imo. Great if you’re in a budget and was great exfoliation!

Not as good as the real thing
I was really hoping to get a less expensive alternative to Dr Melaxin’s version. This just isn’t cutting it - it totally is not as effective, so I’m tossing this and going back. This one just doesn’t pill up as effectively.

Not as effective as original Dr. M
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.
