From UK, live in Singapore, just returned from one hot, sunny week in Thailand. Son, 9 years old has returned with face covered in small, raised spots like tiny pimples, predominantly on forehead, nose and either side of, and on his chin. We had a 'free' week with food during which he ate enormous breakfasts, especially fatty bacon, fried bread and pastries for breakfast and fizzy drinks and milkshakes later in the day. We used SPF 30 and 50 reapplying every hour and spent most of the time in the pool or sea. He showered every evening and used after sun cream and insect repellent. I thought the previous two reasons were the cause. He has no spots anywhere else; they are not sore, dry, weeping, puss-filled or itchy. We have been home for four days now and there is no change.
