Detailed answer

Dry skin and allergies can have a connection because dry skin often indicates a compromised skin barrier. When your skin lacks sufficient moisture and essential lipids, it becomes more susceptible to irritants and allergens. The skin's natural barrier function plays a crucial role in protecting against external elements, including potential allergens. Dry skin has a weakened barrier, which can allow allergens to penetrate the skin more easily and trigger allergic reactions. Additionally, excessive dryness can lead to itching and scratching, further compromising the skin's integrity and exacerbating allergic reactions. It is important to keep the skin adequately hydrated and moisturized to help restore and strengthen the skin barrier, reducing the chances of allergic reactions.
