RE: Cornstarch + Unsweetened Cocoa OK...this sounds really nuts but for years and years I've been using a $40/small bottle mineral powder foundation. I have it in several tones which can be mixed. I also have oily skin - that I thought would dry up now that I'm almost (cough, gag) 50. I never use liquid/cream foundation. I read somewhere that a gal who was into homesteading, etc. had mixed up cornstart + unsweetened cocoa (for color) for use as powder make-up. I thought, "Well, cocoa is an antioxidant..." and I thought I'd give it a try. OMG! I love it. I mixed up just enough unsweetened cocoa to match my skin tone and it looks great. I use a big fluffy brush to apply this mixture (as used for the mineral foundation) and polish until the excess is removed. I still like my mineral powder as it adds an interesting tone/sheen. But a base of the corn start + cocoa mixture keeps the shine away and I love how my skin feels. I need a "blot" once per day (afternoon) instead of 3-4-5 times a day. Here it is 8 p.m. and after a little blot - my skin doesn't feel make me feel like I'm desperate to wash it. Sounds crazy - but give it a try. God love this woman whoever she is. My oily skin is managed + I can stretch the mineral powder make-up. Thanks for reading this and I hope it helps someone else!
