What to do about impaired skin barrier function

When the skin barrier function is impaired, the following measures can be taken to promote repair: 1. Discontinue using cosmetics and skincare products with strong irritants, and switch to gentle, non-irritating alternatives. 2. Use products containing moisturizing ingredients such as hyaluronic acid and glycerin to help restore skin hydration. 3. Apply sunscreen when going outdoors to protect the skin from further UV damage. 4. Under medical guidance, use topical medications such as vitamin E ointment or tretinoin cream to provide nourishment and alleviate discomfort. 5. Consume a diet rich in vitamins, minerals, and protein—such as apples, grapes, and other nutritious foods—to support skin repair. 6. Maintain adequate sleep, engage in moderate exercise, and avoid unhealthy habits like staying up late or smoking to promote overall skin health.
