What should I do about damaged skin barrier on the face?

When the skin barrier on the face is damaged, the primary goal is to repair and protect the affected skin. The following are some recommendations: 1. Gentle cleansing: Choose mild facial cleansers and avoid over-cleansing, which can further damage the skin. 2. Moisturizing and nourishing: Use moisturizers containing reparative ingredients such as hyaluronic acid and squalane to help lock in moisture and restore the skin's barrier function. 3. Avoid irritants: Minimize the use of skincare products containing irritating ingredients like alcohol and fragrance, and avoid direct sun exposure and friction. 4. Nutrient supplementation: Support skin barrier repair through a balanced diet or supplements rich in nutrients such as vitamins C, E, and zinc. If the skin barrier is severely damaged or fails to recover over time, it is advisable to seek medical attention promptly.
