I work at a pool. For some people, chlorine is great for skin, but for others its really bad. depends on skin type. A lot of people think a bunch of chemicals are in a pool, but in most pools, its just plain chlorine at about 8-10% which is exactly the same as Clorox Bleach, only clorox is 2-3%. People fail to realize they swim in bleach!!! Sometimes we add some muriatic acid to balance pH, but this could be the only thing that really affects someones skin. pools will dry out your skin a lot, but for some people, they can help.
