I have self-diagnosed myself with polymorphous light eruptions, and I know that sounds annoying to someone who has dedicated their entire career to skin care. But every time I am at the beach in extreme sunlight, around day 2 or 3, I start developing a bumpy and itchy rash. After much research and comparing online images to my condition, it appears that I have a sun allergy that results in my rash. I have done some online research as well to help prevent or treat this condition because it is extremely uncomfortable, and a common answer is Vitamin E. Is this the right treatment? Is Vitamin E a good solution? Would it be best to take a Vitamin E supplement or use a Vitamin E serum or cream?
