I have an 8 yr. old son who has had KP most of his life.Over the past few years we noticed when he is in pool water or river water the condition starts going away .It actually does a complete 180. Does anyone know if the water is doing something or is it just due from him getting more sun exposure on his arms and legs? This doesn't happen when he takes a bath or shower.Help !

it sounds more like its the sun exposure.
For how long does it go away?

Stays gone maybe about half a week.as soon as we get back home from camping or something we've been doing outside for a while it goes away.This trip, it went away in 4 days maybe sooner.

Hi there, im 100% sure it's the sun, i've said it time and time again, unfortunatley the best relief for KP is obtained from sun exposure, a lot of people find that to be the case, when i went on holiday for a week to sunny spain and came back , EVERYONE had noticed the improvement in my skin..theres no harm in a little sun exposure, as long as he's safe, and especially if it helps with his KP
