What can I do for seborrheic keratosis?

Sheck with your doctor before treating any diseases. There's a couple of things related to that condition that relate to a vitamin A deficiency which usually is not food related. It's more gallbladder or liver. You're not producing the bile to extract the vitamin A as well as vitamin D. Also it could be a vitamin B2 deficiency as well. The B vitamins are important. So the last point I would look at is your ratios of Omega 6 to Omega 3. Add more Omega 3 fatty acids and get rid of the soy oil and the corn oil and the cottonseed oil can greatly help all skin problems. And if you're deficient in Omega 3 you definitely will notice scaly, dry, flaky skin and abnormal skin. Vitamin A is really the vitamin that helps you differentiate the skin cells.
