Detailed answer

Dry weather can exacerbate facial eczema by reducing the moisture content in the skin, leading to increased dryness and itchiness. Low humidity levels can impair the skin's barrier function, making it more susceptible to irritants and allergens. Additionally, cold winds during dry weather can further strip the skin of its natural oils, resulting in further dehydration and irritation. It is essential to moisturize frequently and protect the skin with a barrier cream or moisturizer to minimize the impact of dry weather on facial eczema.
