My dd (11) has joined a swimming club and is now swimming twice a week for around an hour each time. She's started to come out in a rash afterwards, mainly on her arms. Do you think this is a reaction to chlorine? It's a flat rash and slightly itchy. She's been swimming regularly since she was 5 and hasn't had any problems but previously was only going for about a half-hour once a week. She really loves swimming and would be heartbroken if she had to stop. She had very mild eczema as a baby but no problems since. I wondered about using some kind of barrier cream before she swims but not sure what to try. Also reminding her to shower well afterwards. Any thoughts welcome.
