Does anyone here use Pro-Active facial products? If so, have you had a problem with your pillowcases becoming discolored where you sleep? It doesn't happen to all my sheets, so I think it's dependent on the dye in the sheets. I just put a brand new set of flannel sheets on my bed last Sunday that I had ordered from The Company Store. I took them off today to wash them and noticed the pillowcases were discolored. I have at least 2 others sets of regular cotton sheets in which the pillowcases are also discolored. Anyone else who uses this product have this problem?!!!!!
