— -- During the winter months, people wear layers of clothes to protect their bodies from the elements, but they don't always take steps to protect their skin. Some may end up paying for this oversight: The lack of humidity in the air, combined with dry indoor heat, can lead to dry, itchy and even flaking or cracked skin.

You can worsen any sort of predisposition by using harsh cleansers or irritants, or by washing frequently, which removes the protective barrier on our skin and increases what we call transepidermal water loss.

For example, eczema, also known as atopic dermatitis, is a type of inherited dry skin condition. It can start in childhood, and usually affects the face
