White spots on skin from tanning bed? Home remedies to get rid of them?

Hi! I have been going to the tanning bed just to get some color before my vacation to Florida, (yes I know the risks of tanning beds) anyways I discovered white spots on my skin that are initially light red when I get out, no pain, no itching, nothing. But they eventually turn a lighter color. I ve looked it up and from what I found it must be fungus? My main question is, without going to the doctor, what are some home remedies I could use to get rid of the spots? I have this cream called Lotrimin Ultra which is antifungal, it has multiple uses but it s obviously not gonna say for tanning bed spots haha, so does anyone think this could be used on the spots to get rid of them? Thank you
