Ted, you sound SO "with it". I'm going to try your combo of Borax, hydrogen peroxide and sodium Carbonate on my white spots on my tan. (I've been to two dermatologist here in San Antonio, TX, who don't seem to know what it is, and don't think it's a fungus, but My sister has the EXACT same thing in NEW york, and HER dermatologist said right away< " it's an airborne skin fungus". And gave her a scr1pt which cleared it right up. the docs here, won't listen to me, nor give me a script. sooo,,, i'm going to try your "natural" suggestion - hope it works, as I'm embarrassed at how it looks. (I'm a girly girl). If you find out anything more about "fungus" making white spots on tan skin, - please post! I'll post on whether the above concoction does any good. God bless! ellie
