Several years ago, I learned that my family has a history of seborrheic dermatitis and eczema. Ifound that out because I started to get litte red patches of dry skin on my back, abdomen and above my eyebroww during the winter months. It took months of doctor's visits to rule out fungal infections, yeast infections, psorisis, etc...ultimately, we determined that it was a very mild case of seborrheic dermatitis.
Afterwards, I switched out my shampoo and conditioner to natural varieties. I threw out any lotions that contained plastics or poisons in them. I began using cocoa butter religiously and within months, my skin cleared. Now the rash only shows up every now and again, but I have learned to manage it. I find that applying cocoa butter twice a day when it is active eliminates it within a few weeks.
So, I just said that I got rid of anything with additives in it. Well, I kept one. I kept a product called Dermarest. Dermarest is a medicated lotion that contains parabens! Damn it right? But you know what, it works and I am hoping that the company comes up with a lotion that doesn't have these things in it. I hardly ever use this lotion, but when I have a stubborn patch of dry, red flaky skin in my eyebrow, I use this lotion once a day for two weeks, and then it just goes away. It goes away faster than just using cocoa butter. I'm pretty sure it has to do with the zinc that is in the lotion, but I have no idea.
I've discovered that the key is to use it for two weeks and stop even if the patch hasn't disappeared. After that, I go back to just cocoa butter and it just heals. I've tried other ways to heal these stubborn patches, but nothing has worked but this method.
Now, if you have dry, red skin during the winter months, you may want to try using this every other day on your skin (face and body) to see if it helps out. Like I said, I barely use it, and usually only in the winter when the seb. derm gets worse. I have a friend who experiences dry skin every winter and as soon as she begins using this lotion, her skin stays moisturized and the redness disappears. It's sort of awesome.
