I have extremely dry skin in general and it gets worse in winter. My feet and hands suffer the most, they feel very tight, dry and itchy.
I've found some natural remedies that work well. I'm using organic cocoa butter on my skin as a moisturizer now. I've realized that many of the lotions sold at stores have drying ingredients like alcohol in them. All natural cocoa butter is pure and it's an excellent moisturizer.
I also rub down my body with a mixture of olive oil, coconut oil and almond oil before baths. I put oatmeal in my bath because oatmeal locks moisture into skin. Before I go to bed, I use another organic moisturizer with beeswax in it.
I've been able to cure my chronic dry skin this way. My feet are not itchy anymore!
