The dye reacts with moisture and disperses, leaving large smudge spots on the sheets. This magnifies the amount of oil the sheets are taking off your face. So, using these sheets, it might appear that you're removing more oil than you actually are. Clean and Clear oil-absorbing sheets could also be hard on your wallet. The Body Shop uses rice paper to make its oil-absorbing sheets.
Rice paper is a natural ingredient that's cheap to manufacture.
It's also soft on the skin, but rougher than polypropylene. The Body Shop adds synthetic minerals called titanium dioxide and iron oxide to their sheets. Titanium dioxide gives the sheets a white colour. The iron oxide absorbs moisture from the skin's surface. On top of these, the Body Shop adds a talc powder.
