Skin barrier repair involves using gentle, hydrating skincare products that restore its natural function. Key ingredients like ceramides, hyaluronic acid, and fatty acids help strengthen the skin’s protective layer. Avoid harsh exfoliants and opt for a mild cleanser. Hydration is crucial, so follow up with a moisturizer that locks in moisture. Lastly, protect your skin from environmental stressors like pollution and sun exposure to prevent further damage. Consistency is key for long-term results.
