Detailed answer

Dehydrated skin is lacking in moisture, which can compromise the skin barrier function. A weakened skin barrier may allow irritants, allergens, or histamines to penetrate the skin more easily, triggering an allergic reaction such as hives. However, it is important to note that hives can have various causes, including allergic reactions to certain foods, medications, insect bites, or underlying health conditions. If you frequently experience hives, it is recommended to consult with a medical professional for proper diagnosis and treatment.
