Could be dermatitis, eczema. But most likely it’s nothing too serious if you live in states that are going into winter such as Illinois it could just be your skin reacting to the cold and drying up. I suggest continue using lotion but don’t use anything scented or weird use something like cerave you can get it at any Walmart target Walgreens whatever! And also check if you have any bumps or rashes! You could have bug bites or one of the things I said before. For now just use a gentle moisturizer and keep warm if winter and if it still persists or gets worse call a doctor on the phone or talk to a parent who may know :)
