I feel ya I've been having the same problems. You can also use a face wash that has the exfoliating beads in them, a wash rag, or they sell exfoliators at the store. And I use Aveeno on my face everyday after washing and it's helped a lot! I hope this helps you, I know how embarrassing it is having dry skin under make up. Lol @acjones186
After washing your face and its still moist use your fingers and rub in a circular motion, all over your face or just the spots with dry skin. You'll be able to feel the dry skin scrub off. And using a facial moisturizer everyday really helps too. :)
