What can I apply to my wound?

I have skin peeling behind one of my ears and I know it isn't eczema or proriasis or any skin infection and I think it's because of excessive moisture behind my ear from bathing or sweating. Can you suggest anything that I can apply to speed up the recovery process? And I don't want to visit the doctor cos I'm still a kid and I'm quite sure it looks quite scary behind my ear cos the skin's been peeled off and it's red and raw and slimy so I don't want my parents to see or know. And I'm sure I've got this when I was younger, like when I was 6 or something and it recovered completely cos I didn't even care about it. So I'm sure this can recover on it's own just that I want it to more quickly cos I tie my hair up in school and I dunno if my friends would notice the raw and red skin behind my ear and freak out xD thanks:)
