When the temperature changes from warm and humid to cool and dry, there can be drastic changes to the skin on hands and feet. By the time winter rolls around, hands and feet look more reptilian than human. Using commercial soaps do further damage by striping the first layer of skin, leaving hands and feet without needed moisture.
The first step in restoring winter skin is changing to a natural soap, such as those made with goat's milk, lye, glycerin or beeswax. Sodium laurel sulphate in commercial soaps and shampoos was added to produce more lather, but was originally created by scientist to remove the first layer of skin to facilitate testing of skin products. Scientists never let a chemical go to waste, so it was sold to soap manufacturers as a foaming agent.
The US Department of health and Human Services has a list of products with sodium laurel sulphate. There isn't much that anyone can do to improve skin until they stop using this form of sulfuric acid.
Moisturize hands every time you wash them. After bathing, moisturize every place where the skin is dry, itchy or painful. Use a moisturizer with the least ingredients. Making your own moisturizer would be best. Add any one or two of the following ingredients for faster healing: raw honey, aloe vera gel, witch hazel, rose water or essential oil from chamomile flowers.
Remember that shampoos, dish detergent, detergent for washing clothes and other household cleaners contain sodium laurel sulphates. Avoid these detergents by switching to a different brand or by wearing gloves when cleaning. Drink plenty of water to keep skin hydrated. Don't wait until skin is broken and inflamed to treat dry skin. Be proactive and begin caring for your skin before it turns into a medical condition.
