Dry skin occurs when the skin is unable to retain enough moisture to keep itself hydrated. Practices and conditions like bathing or showering too frequently, using harsh chemical-laden soaps, aging, certain medical conditions, and low humidity are all potential factors leading to dry skin.

The water content of the epidermis (the outermost layer of skin) tends to reflect the level of humidity around it. Especially in late Fall and all during Winter, climatic conditions will negatively affect skin that isn’t well protected, hydrated, and nourished.
Low humidity, low temperatures, and wind create negative effects on the skin barrier and make skin less able to function optimally.
“Think of the epidermal skin cells as an arrangement of roof shingles held together by a lipid-rich ‘glue’ that keeps the skin cells flat, smooth, and in place… Water loss accelerates when the glue is loosened by sun damage, over-cleansing, scrubbing, or underlying medical conditions—or by winter's low humidity and the drying effects of indoor heat. The result is roughness, flaking, itching, cracking, and sometimes a burning sensation.” — Harvard Women’s Health Watch
You don’t have to have mature skin to experience dry skin in Winter, especially if you already have some sort of dermatosis or skin condition. These can be exacerbated and combined with dry skin when exposed to wintry conditions or low humidity environments even in younger people. No matter their age, people with atopic dermatitis (also known as eczema), for example, can really suffer in the colder months with very dry, rough, peeling, and cracking skin.
In more mature skin, however, we see changes in skin structure begin to accelerate with age and which contribute to the drying of the skin. The skin starts to lose its ability to regenerate and along with the cumulative effects of environmental insults, skin barrier function and hydration of the skin decline. Over time, skin becomes more susceptible to irritants and allergens that enter through the skin and this can lead to inflammation and itching.
A proactive measure to take right now before Winter and cold weather arrives is to make sure your skin is well mineralized. Without adequate mineralization that prepares skin to receive hydration and retain it, moisturizers will be much less effective.
Finally, here are a number of additional tips that will help you have an easier time keeping your skin hydrated this Winter:
Apply most or all of these tips and your skin should get through the cold dry months resiliently. A well-rounded holistic approach like this to retaining skin moisturization is your best strategy for supple hydrated skin this Winter.
