My daughter’s eczema looks the same as that and she has it all over. Try a combo of CeraVe and Aquaphor and usually we have success within a couple of days. Sometimes we have to do an oatmeal bath or two during these dry months.
Doesn't look like it to me
I'm not sure it's ringworm, but treatment for that is usually a simple OTC anti fungal. My son's eczema looks a bit like that, do you think that's a possibility?
