I think I've found a really good sunscreen for oily skin. It's the Anthelios AC spf 30 for oily skin, and has Mexoryl, so it must be effective. It says it works against UVA as well as UVB. It isn't at all oily, and although it's a bit tricky to apply as it has the consistency of very thin cream, it goes on without any stickiness. The only thing I'm not crazy about is that it does leave a surface shine, but I matte this down with powder. Hope this info may help others looking for a sunscreen for OS skins.
