I recommend this foundation for oily skin.

I recommend Estée Lauder Double Wear Foundation. I don't have oily skin, but I'm using it because it's summer. It adheres perfectly to the skin and isn't greasy, so it's really great for the summer.

I don't think people with dry skin should use this. If you're struggling with oiliness in the summer, give it a try~ I recommend testing it in person before purchasing because of the color.
