My son has KP on his lower part of arms and upper parts of legs, he is 10 years old, he had this for a long time. I took him to dermatologist and was recommended regular out of the counter moisturizers :/ especially in winter time, when skin gets more dry. But it never went away completely.
Then this year we went on vacation overseas to Armenia, we spent 2 months there. Guess what? All his skin was nice and smooth by the time we got back to the States!
I was shocked! Now my question is maybe local water makes it worse? or the wheat? or dairy?
While on vacation he ate everything fresh and organic, drank water from the faucet which is very good there. Showered with same water. So I do not know what exactly causing this Keratosis pilaris but I am so curious to find out.
