there's a product by gatsby, u can get at guardian or watson, it's a black film which can absorb oil very well. try to look for gatsby product in a small white box. the film is black but after u rub it to oily skin, it will absorb the oil and become transparent. very effective, but it absorbs oil only, doesnt control oil production from ur face. so if ur face is the type which becomes oily quickly, then need to use it often la.. it's 70 pieces for about rm7. should buy one and always keep in ur purse/pocket, so that later if want to take picture or anything, can always use that and ur face wont look shiny.

depends on how u use it. u're not supposed to wipe ur face, just dab the thing on the oily part. and if scared on infection, use different film for each part. my fren wanted to save money, so he use one film for the whole face. one film about the size of credit card. i dont think it's the ideal solution to have non-oily face, but it's helpful to carry a pack along especially when there's a function, party, etc.
