Dry skin HELP!

Brooklyn

I have never had dry skin like this before.. normally my face stays very oily actually but for some reason my face and my waist band area has been so dry and flaky.. and actually my face feels very brittle? And sandpaper like? I have tried moisturizer masks, all the face lotions like tea tree oil and everything. Even drinking a LOT more water. Nothing is working! Any advice?😔
