Detailed answer

Dehydrated skin lacks proper moisture levels, which weakens the skin's natural protective barrier. This compromised barrier can allow irritants and allergens to penetrate the skin more easily, leading to an increased risk of allergic reactions. The lack of adequate moisture also impairs the skin's ability to heal and may exacerbate symptoms of existing allergies. Therefore, it is important to keep the skin well-hydrated and nourished to maintain a healthy skin barrier and minimize the chances of experiencing allergic reactions.
