Core Viewpoint - The increase in cases of dry eczema during winter is attributed to dry air and reduced skin moisture, rather than excessive humidity [2][3]. Group 1: Causes of Dry Eczema - Dry eczema, also known as lipid-deficient eczema, is prevalent in winter due to cold, dry air that dehydrates the skin [3]. - Low temperatures lead to decreased sebaceous gland activity, weakening the skin's natural barrier and reducing its moisture retention [3]. - Frequent hot showers and indoor heating further exacerbate skin dryness, contributing to the onset of eczema [3]. Group 2: Symptoms and Identification - Key symptoms of dry eczema include dryness, itching, redness, and flaking of the skin, often resulting in rough texture and potential cracking [5]. - Commonly affected areas are the lower legs, inner elbows, and behind the knees, with infants often experiencing symptoms on the face and neck [5]. - Symptoms tend to worsen with heat exposure, particularly after bathing or entering heated environments, creating a cycle of itching and scratching [5]. Group 3: Management and Care - Recommended management includes avoiding hot water and excessive washing, with bathing frequency limited to 2-3 times a week and water temperature kept between 37°C to 40°C [8]. - It is crucial to apply moisturizer within three minutes after bathing to maximize hydration, using products containing ceramides, glycerin, and hyaluronic acid [8]. - Maintaining a stable emotional state and improving environmental humidity can also aid in managing symptoms [8].
