sorry, no scientific stuff...but from personal experience, swimin every so often i found helped to dry the zits up. but too much chlorine (as in swimming every day) actually made the problem worse because the skin got too dry. i used to go swimin 1-2 times a week, but immediately after i got out of the pool and showered, i put cream on my skin to prevent from over drying. i found this worked for me. it was actually my dermatologist at the time who suggested i try swiming every so often to help "dry up" the spots. if i have a big event coming up, i usually hit the pool once during the week before...just to dry up anything that is there, or may be forming. but, just remember, it IS a chemical....

Thank you!

I think a combination of chlorine and the sun helps. But that is dangerous too I guess. I used to go to the tanning bed, and it would clear up every time. Swimming and sunning always did too.
