I have been using ProActiv products for years now and I feel I shold shed some light on the subject of their much loved product, the Refining Mask. I have used it on and off for years now, and really I am not impressed. It does do "something" per se, however it certainly doesn't provide the results that I wa expecting from ProActiv products in general. I have used itt at all times of the day and night, multiple times per day and night and yet I am really not impressed with the product. It does seem to make my skin seem a wee little bit softer but the desired result that I was expecting is fewer and lessened blemishes!!! That just doesn't seem to happen, no matter what I do! I have no idea what I am doing wrong, but I suspect that the problem is just that the product doesn't do what it promises to do! And OMG, nevermind the fact that it smells to high heaven!!!! It smells just terrible! And I am pretty tolerant to skin care products. If you have more patience, good luck and please let me know what I am doing wrong! Thanks!
