I had always spent my holidays at my parents' house at the seaside. One summer, when I was 18, I got small bumps on my neckline, forearms and shoulders accompanied by unpleasant itchiness. I thought I was having a one-off reaction to the sun. So I waited for the spots to go away and I continued to enjoy the sun for the rest of the summer.
Not really...they got worse! Because I love the sun, I always tend to take advantage of the faintest ray of sunlight as soon as the weather is fair. Each time I was in the sun, the reaction came more swiftly and was more severe with even more spots and itching! I ended up telling myself that my skin could no longer handle the sun and I might have to stay out of it for good.
In fact, I went to an online discussion group. Another Internet user told me she had the same problem as me: apparently it was called summer light eruption. She told me to go see a dermatologist. So I made an appointment and he prescribed an appropriate SPF 50 sunscreen from a pharmacy. Now everything has been great for two years! (Even if I don't bake in the sun all day long!!!) In any event, after years of allergies, I can finally get back in the sun!
