I read a post here about someone who was having excessive oily skin lately and commented that she (?) had gone thru 3 of those sheets in day – now I can’t find the post, so…. a cheap alternative is to cut up squares of white tissue paper- the kind you use for gift wrapping and use that instead. I had heard of this a long time ago, but at that time I was using Proactiv very successfully and never needed to try it. However, the Proactiv suddenly stopped working last fall 🙁 , and I recently remember this and gave it a try. It works like a charm……and is a lot less costly. Soaks up the oil without removing all your make-up.
