Wash yourself with sobalene when you get out of the pool. One of the mums in my classes recommended Aveda products for helping with the skin (I can't remember what it was called though).
Yeah that, do you have a price line nearby? They have some lovely moisturizers that are great for frequent swimmers, just ask someone that works there, they can help you out. I can't remember what the one ive got is called but it's from the palmers range
