Itchy symptoms caused by dry skin often have no primary lesion, but scratching can lead to marks, blood scabs, and hyperpigmentation. This type of itch is common during the winter season. Another group affected is the elderly, who may experience itchiness related to skin aging, insufficient nourishment, and dry skin. Another condition is atopic dermatitis, which is more common in children and related to congenital immunity. It often presents as dry skin, erythema, scales, and itching on the flexor sides of the limbs. Whatever the cause of dry skin and resulting itchiness, the following points should be noted in daily care: First, the water temperature for bathing should not be too high, recommended to be below 37℃. Second, during bathing, it’s advisable not to use alkaline substances such as shower gel, soap, scented soap, sulfur soap, or even laundry detergent, as they can exacerbate skin dryness. Opt for mildly acidic or amino acid-based shower gels instead. Third, after bathing, it is recommended to apply body lotion, like baby cream and other special-function moisturizers such as barrier repair creams, to help alleviate itching due to dry skin.
