Moisturizing is essential to maintain healthy skin during the winter. The recommendation has always been to moisturize immediately after the shower to best lock in moisture. Some recent studies suggest it may not be as important whether you moisturize damp or dry skin. The bottom line is your skin simply needs added moisture. Dry skin can lead to irritation, breakouts, and itchy, red, flaking rashes called Asteatotic dermatitis—which unfortunately, we see quite often in the winter, especially on the lower legs. This condition will usually clear up with a prescription ointment from the dermatologist.
