THESE ARE NOT INTENDED FOR THE FACE. The reviews that complain about the wipes being too harsh or ineffective on their face aren't going to be particularly helpful to you if you are looking for a KP treatment product.
I have KP. It affects my arms, my legs, and occasionally my abdomen. It is unsightly and embarrassing, and I frequently find my wardrobe choices limited because of it. Believe me, I have been trying for YEARS to find something that can help treat it (sadly, there is no cure). These cloths are part of a regimen that I have found to work!
I use a cloth after my shower when my pores are most likely to get the greatest benefit. One cloth is enough for both arms, both thighs, and my abdomen! Once I let the product dry, I then follow up with another KP cream product that has recently been released by a brand that is found in any drug store. BIG, noticeable difference. I tried using just the follow-up cream and didn't see as marked a difference as I did with these wipes.
Yes, they smell slightly of milk. Honestly, it isn't horribly offensive, especially when not used on the face--where it has no business being anyway.
