Normally I have very oily skin on my T-zone and normal skin every where else. But lately, my skin has become dry. It's flaking and it looks horrible! It was getting a little dry, and then I switched to Bare Minerals and I use their foundation, primer, and mineral veil. Do you think it's because of the season change(my skin always gets drier during winter, just never this dry) or the Bare Minerals? Also, if you have any tips on getting rid of dry skin that would be great!
