Of course, there are expensive foundations that you can special order, and drop a lot of money on. You will have to gamble on them, just as you would if buying foundation from the local drugstore, but you can find some gems at the drugstore if you know where to look.
Don't worry, I'm going to go ahead and take the gamble out of the equation, and give you some excellent choices that have been tried and tested on oily skin. While I could stick to my top choice, and list only the best drugstore foundation for oily skin–at least my opinion of which is the best–not every store is going to carry every product.
So let’s start with what makes certain foundations resistant to skin oils. This could help you choose one, even if you can find an exact match for something on the list.
How to Choose The Best Drugstore Foundation for Oily Skin
Tinted moisturizers and BB creams combine all the best elements, like hydration and sun-blockers, and they work effectively on oily skin. Combine that with their perfect blending, and you have a staple of safe products for oily skin.
Any foundation that has skin replenishers in its formula usually won't stick, clump, or clog. This allows the formula to work with you, and show off your natural beauty while enhancing the skin underneath.
Any matte-finish liquid foundation is probably going to be your safest bet. They are easy to blend, great for holding back oily shine, and will cover up blemishes quire well. Perfect for oily skin, humid climates, or a combination of both.
Matte-finish liquid foundations also apply light and let you build coverage easily. So even if you can't find the recommended foundations in the right color, stick with matte-finish liquid, and you should be safe.

Top 6 Foundations for Oily Skin
In this writer’s opinion, the best drugstore foundation for oily skin is Neutrogena Skin Clearing Oil-Free Makeup. It works great on oily skin, and it’s also a safe way to treat skin that is prone to break-outs. It’s shine free, and it won’t clog up your pores. Though it is a little more expensive.
Boots No7 is another good one, around the same price as the Neutrogena, and has built-in protection against the sun: SPF 15.
If you are looking for a lower cost option that still works great, CoverGirl Clean Oil Control Liquid Makeup is low cost and designed specifically to control oil without drying out your skin.
You can also see about using your current foundations by doing the right prep work. If you have that one perfect color that you don’t want to give up on, you can give these ideas a try. Priming and prepping won’t work for every foundation, but it might be worth a shot.
The Bottom Line
So that's it. Now you know how to find the best drugstore foundation for oily skin, have some choices to pick from, and some backup advice to save your current favorite foundations, even if they don't agree with your oily skin.
