My skin is quite sensitive and I went swimming last week and reacted to (presume) the chlorine in the water, face went red and sore. It's been left very very dry and rough, I have flaky skin patches all over. I've just been moisturising so far but I think I need some sort of gentle scrub to get rid of the flakiness. I don't ever usually use anything because of sensitivity, so any recommendations would be great?
