I've been researching (googling?) around this issue but am thinking I'm going to have to see a dermatologist at this rate unless anyone else has come across this. My DSS2 on holiday last year for the first time seemed to get a red allergy type rash on his legs when he went into the sea but not when he went into the pool. He didn't get it on his arms or upper body which made us think it was something to do with the sunscreen because he wears a long sleeve rashie so his legs (and obviously a bit on his face) are the only large areas covered with sunscreen. None of the rest of us had any issues (because my first thought was that there might be some algae/chemicals etc in the water) so presumably it was just something specific to his skin.
We went to a pharmacy, explained the issue and the pharmacist confirmed this often happens (more so with kids prone to eczema which DSS2 is not) and provided an alternate sunscreen that seemed to resolve the problem. I'm now looking to stock up some more sunscreen for all the kids... And it's all in Greek on the tube... And I stupidly didn't think to ask the pharmacist at the time about what was the active ingredient (or rather the active ingredient to avoid).
Has anybody had this skin reaction that seems to be specifically to sea water and have sourced a sunscreen that doesn't irritate the skin?
