What should I do if the stratum corneum on my face is thin?

Thin facial stratum corneum can be improved through the following methods: 1. Gentle cleansing: Choose mild, non-irritating facial cleansers and avoid over-cleansing to prevent further damage to the stratum corneum. 2. Moisturizing: Use moisturizers, lotions, or serums containing hydrating ingredients to provide sufficient moisture and nutrients for the skin, thereby strengthening the skin's barrier function. 3. Avoid irritation: Minimize the use of skincare products containing irritating ingredients such as alcohol and fragrances, and avoid excessive rubbing or squeezing of the skin. 4. Repair the stratum corneum: Use skincare products designed to repair the stratum corneum, such as those containing ceramides or squalane, to help restore the skin's protective barrier. 5. Healthy diet: Maintain a balanced diet and consume plenty of foods rich in vitamins and antioxidants to support overall skin health.
