I, too, have discovered the cause of my keratosis pilaris: bovine casein, the main protein in cow's milk. There is no doubt it's bovine casein. As long as I stay away from bovine casein, I don't get the rash. When I eat hard cheeses made from bovine milk, in about 3 days, the rash appears. Happens the same way every time I eat cheese made from cow's milk. I don't drink milk now as an adult, but I sure drank a lot of it when I was a child, and I had very obvious KP lesions on my jawline, back of the upper arms, and on the forearms, buttocks, and thighs. Goat's milk, and cheese from goat's milk, or sheep milk cheese doesn't cause this to happen. So, I really encourage anyone with KP to eliminate all cow milk products from their diet for a month, and see if the PK disappears. Then re-introduce bovine milk products again, and see if the lesions reappear.

I had KP when I was in elementary school. My Grandmother took me to our GP and she didn't know what it was called my father had it as well when he was younger. I took my daughter to her pediatrician for a checkup and we had noticed the bumps on her face, arms, and legs. The doctor said let's check on my daughters Keratosis I was floored this is the first time I ever found out what it was that we all had. Plus side she said that we will never have a problem with acne due to the fact that our face does not produce oil like people without KP.

It is vital to note that casein is in many different foods. Anyone interested in seeing if they can improve symptoms through diet should be very thorough and check all their food labels. Products that often have casein in them include cold cuts, candy, and bread products. Your best bet is to stick to a very simple diet of lean meats, fish, vegetables, and fruits for a month.

I'm 40, and believe I've had keratosis pilaris (KP) since I was 10 years old. I have always been allergic to dairy. I use soy and other non-dairy products. It seems to be worse in winter. I do not believe there is anything that makes it worse. I do know that bergamot, sunshine, lotions with alpha hydroxy acids and lotions with urea are the only things that have helped me. I have eliminated all kinds of things from my diet to find if there is a relation to foods. But that seems not to be the case at all. For me, KP is not food related.

EXFOLIATION! In the shower I use a sandpaper like foot callus file to exfoliate the skin on my upper arms and backs of my legs where I have it mostly. It knocks the tops off the pimples that are ready to open and gets rid of any dead/dry skin waiting to clog up other pores. This doesn't get rid of it all, but I see a huge improvement for me especially with regular doing. You have to go easy when you first start otherwise you will have red scraped and irritated skin. Try it, I promise you will see a difference in a couple of days. You need to then regularly exfoliate to keep the dead skin from accumulating. More often in the winter and less in the other less-drying seasons.

I'm not entirely sure what caused my KP to flare up. I noticed it when I was about seven. I asked my parents why I was getting small bumps on my face & legs but they were baffled. My dad has had skin problems all of his life. He was diagnosed with psoriasis as a young adult. My mother never had any problem with her skin. It became worse as I got older. They began to appear on my face, upper arms, above my knees, below my buttocks and on my buttocks. I used to pop them as a child and sometimes still do as a young adult. They have somewhat vanished on my cheeks but have yet to disappear on my arms and legs. I'm not really sure what to do to get rid of them. There is a list of things that could possibly work and I have spoken to several dermatologists and apparently they don't know what KP is. I plan on trying the obvious treatments first then going to a doctor if it doesn't work.
