My sister in law sells arbonne products and I've tried a few that I really liked. Unfortunately the NutriMinC RE9 RElease Deep Pore Cleansing masque wasn't one of them. The first issue I ran into was that it really irritated my skin. I may have left it on too long but it definitely wasn't made for very sensitive skin like mine. Overall it didn't really deliver what it promised with the pore cleansing and it was pricer than a lot of thins that work better you can buy in the drug store. Effectiveness The whole reason I went ahead and bought this product was because I have some super gross and very deep blackheads that I just can't seem to rid myself of. They aren't that noticeable until you get up close but once you do, things get ugly. I was disappointed that this mask didn't really clean my pores out like it said it would and I felt like I'd wasted time and money when it didn't work as advertised.
