What in the world makes you think it has anything to do with your colon? It sounds like you have psoriasis to me. Psoriasis is a skin disorder that causes the skin to produce too many skin cells. No matter how many times you wash your face or what kind of creams you use, your skin continues to flake, peel or crust. You can buy over the counter medicine that contains tar for relief.

Hiya, try aloe vera juice, it cleanses the colon when you drink it.
