WHY not Bare Essentials? Somethings are worth paying for. I know it's a bit pricy, but the foundation is TOTALLY worth it! I can be broke out and this stuff will cover it up AND will stay on. You don't have to buy all the fun stuff, the eye shadows and stuff like that...but I would consider the foundation alone. You dont' break out, cause it's not heavy like foundation. It'll last cause it's more than just a powder. I've been using this for about the past 4 yrs and have bought it for my mother and a friend as well.
Otherwise...without spending, too much...I would recommend a good concealer. Physician's formula (drugstores) has great concealers and then just get a mild powdery foundation and use that when you need to. But unless youa re broke out you won't need much...
