I'm of fair complexion with dry, sensitive skin so have suffered with keratoses pilaris, eczema, cracked skin on hands during winter and various rashes at different times in my life. I've found that when my diet is clean (free from foods and beverages high in fat, additives and preservatives) my skin tends to be clear also. I supplement my diet with a probiotic in capsule form daily, which also seems to help prevent colds and gastro-intestinal maladies by boosting the immune system through balance of the intestinal flora and keeping yeast (fungus) in check. I also use ginger, chili powder, cumin, turmeric, garlic and onion regularly in my cooking.
When I was in my twenties, I went for a series of 11 colonics over ten weeks. I was amazed that the keratosis pilaris on my buttocks had completely disappeared and my skin, as smooth as silk. It was clear that the detoxification of my system through the colonic regimen had created the desired effect. Hope this helps!
