Detailed answer

Dry skin can disrupt the natural barrier function of the skin, making it more susceptible to irritants and allergens. When the skin becomes dry, it can also lead to inflammation and imbalances in the skin's microbiome. These factors can contribute to the development of perioral dermatitis, a condition characterized by redness, rash, and bumps around the mouth. It is important to maintain proper hydration and moisturization to keep the skin barrier healthy and reduce the risk of perioral dermatitis.
