There are times -- like this hot and muggy week -- that it's difficult not to walk around looking like a glazed Renee Zellweger. But there are plenty of moderately priced cosmeceuticals out to prevent you from looking like you've just run a marathon.
I'm a fan of La Roche Posay's Anthelios 60. It's an SPF sunscreen that dries to a matte finish, and sells for about $27 at CVS. If you don't need a sunscreen, Vichy Laboratories makes a mattifying, oil-free lotion that prevents shine for about $21. I also recommend Dermelect's T-zone mattifier for you super glowing Renees out there.
