What is the best foundation for oily face and how much is it?

I can't personally suggest one since my face is a mix of dry and oily during several different days. You can check this link, though, according to Cosmo. Here, the top 10 foundations for oily skin are enlisted. http://www.cosmo.ph/beauty/makeup/the-10-best-foundations-for-oily-skin

I really like Happy Skin's "Don't Get Mad, Get Even" liquid foundation (P999). It's lightweight, absorbs oil well, spreads evenly, has a dewy finish, AND cares for your skin :) http://www.happyskincosmetics.com/index.php?id_product=3&controller=product

I love L'oreal's True Match liquid foundation. :) I'm not really great at applying makeup but the brand worked for me! Just make sure to apply it with a clean brush ;)

Mac is highly recommended for oily skin. I'm not "hiyang" though and still searching for the right foundation :)
