On the really hot days of summer, my face can get very oily.My face feels gross, even after my shower. To clean my pores and make my skin feel smoother, I like to grind about 2 Tbsp oats with my mortar and pestle. I add a tiny bit of water to the ground oats - enough to make a thick paste. I then apply the oat paste to my face and keep it on for about 15 minutes or until the paste is dry. Wash off. My face always feels so much smother afterwards.
