I will post my question again as I think that neither Bill or Ted saw it! In the meanwhile I found out the name of this condition: Idiopathic guttate hypomelanosis. The white spots start on the legs, usually appear in older people, don't itch and spread to the arms and chest. It is a discoloration of the skin due to it being "tired" of the sun. My husband has it too but he is British so never had a lot of sun in his life and is very careful as well.

My question: there isn't any real cure "A variety of therapeutic methods, including topical steroids, topical retinoids, dermabrasion, cryotherapy, and minigrafting, have been used for idiopathic guttate hypomelanosis with variable success". I visited a natural doctor in Portugal and he gave me an iodine solution because he thought that it was a fungus, now I know that it isn't but in the meanwhile someone told me that in the old days one used to add iodine to coconut oil to tan better. Could this be a good idea? I tried to add a few drops, first the solution was slightly yellow but the next day it was white again. My husband told me that it was because the iodine disappears in contact with the light. Many people suffer from this problem so some ideas would be welcome!
