Okay, so about a month ago, I stopped using commercial deodorant, and began using a homemade, natural mixture of coconut oil, baking soda, and corn starch. After a couple of weeks, my underarms began getting sore when I would sweat. And then one morning the skin became very dry and scaly and began peeling off in small clumps. It's worse on my left side. The skin left is often red and burning unless I'm entirely dry. Is this an infection or just my skin detoxing from the old deodorant?
