If it is red place it in a tea cup of distilled water only - room temp water only - no warm water. See a dermatologist before you try and put anything on it.
DO NOT WASH IT WITH SOAP anymore. Leave it be. Do not look at it or use it for 1 week. Eat healthy. Work out. do not rub with water in the shower. Do not put anything on it.
I have had issues for 2 years from washing the hell out of it, and not letting it heal. Trust me on this.
Good luck
