I'm curious about skin barrier recovery.

Every year when the seasons change, the skin around my mouth, hands, and the back of my hands turns over so much. Is there anything good for restoring the skin barrier? Even though I drink a lot of water and moisturize, white and red marks like dead skin cells appear. I urgently need to restore my skin barrier. It stings and hurts so much. I really want to restore my skin barrier so I can live without pain. Is there any treatment or management method I can use at this point? If there is a good method for restoring the skin barrier, please let me know!!
