Swimming and Skincare

So, I've been thinking about getting back into swimming, since I miss being active. I have acne-prone skin that's rather sensitive and what I remember from being on swim team is how it used to dry out my skin a bit! I planned on being a morning swimmer so I could get get a workout done before any of my classes, but I could probably do night swimming in a pinch! I was wondering how the swimmers in the AB reddit do their routine or protect their skin from the chlorine?
