I highly recommend you try adding a dime size amount of aquaphor to your moisturizer in addition to the jojoba oil. It's a miracle for dry skin. It has completely eliminated my horribly dry skin and (I'm only in my third week on the regimen and my skin is no longer dry or flaky since I have done this)! I have continued to clear up beautifully since I tried this. My makeup also goes on so much better.
I also recommend you switch to liquid foundation instead of powder. Powder is super drying and in my opinion looks more cakey and less natural than a thin layer of liquid foundation, which gives more of a natural dewy look. I love revlon colorstay (in the dry/normal skin formula.. the oily/combo skin one is too drying). Coverage is great and it looks very natural. Just use a very very small amount and set it with a VERY thin layer of powder.
Also, use jojoba oil as makeup remover. I wet my face, then spread jojoba oil all over my face to loosen the makeup, and then use a good cleanser to wash it all off. Works beautifully and isn't drying.
