Oil Free Blush?
I use bare minerals, i am hooked on it, ive been using it for 4 years and i love how long their color stays.So i would suggest that a good oil-free blush would be from the bare mineral collection.
Lancome "BLUSH SUBTIL - Delicate Oil-Free Powder Blush" is a moisture-balancing blush that is oil-free and oil-absorbing. It blends easily, lasts for hours and never looks dry. You can find it at: http://sephora.com/browse/product.jhtml?id=P54408&
I hope this helps you.
