Does bathing in swimming-pools (e.g., at hotels or water parks), where chlorine is added to the water, brighten your skin?

I've heard from many different people that bathing in pools with chlorine water makes your tan go away, although my doctor friend undoubtedly says otherwise.

The claim is also made in this fake tan company's FAQ:

Yes. Frequent swimming will enhance your body's natural exfoliation. Chlorinated water also tends to lighten the skin, therefore fading your tan quicker.

and on this holistic supermarket's website:

Your tan will gradually fade in about a week to 10 days. Exfoliating, shaving, prolonged water exposure, (especially in chlorinated pools) and heavy sweating can lighten your tan, as all these things contribute to rapid dead skin-cell removal.

    Welcome to Skeptics! In order to keep the scope of the site to a manageable size, we require proof that the claim questioned has proponents. Please edit your question with a proof of that. A quote or a link will do nicely, but "My friend told me that..." isn't sufficient proof. – Borror0 Aug 15 '11 at 2:28
  • @bor: I don't have a link in English handy, but it's a common claim in Italy. See 10k+ results on google in Italian: google.co.uk/… – Sklivvz Aug 15 '11 at 16:18

    I added a link to the claim, I think enough people believe this one for it to be notable. – jozzas Aug 16 '11 at 3:43

    Isn't that first link about fake tans? There probably quite a bit of a difference between a tan and a fake tan! For instance, I don't doubt for a second that fake tans lessen in chlorine water, but have serious doubts about real tans. (both unfounded at this moment, but as they are 2 different things, it seems incorrect to look at them the same way. – Nanne Sep 13 '13 at 17:08

    The second is also about fake tans, but I'm guessing your doctor friend is talking about a real tan (his/her area somewhat, while for wake tans it doesn't seem necessary to add the doctor part – Nanne Sep 13 '13 at 17:11
