Causes of Poor Skin Repair Capacity

Skin care is critically important for everyone. However, some individuals notice that their skin’s ability to repair itself is relatively poor, yet they remain uncertain about the underlying causes. The specific reasons are as follows:

① Over-cleansing

Most people cleanse their skin daily, aiming for thorough cleanliness—ensuring pores are free of debris and enabling optimal absorption of skincare nutrients. However, some individuals over-cleanse: excessive exfoliation and overuse of oil-control products can damage the skin’s natural protective barrier, leading to moisture loss and enlarged pores. Generally, frequent face-washing should be avoided, as it may compromise the integrity of the stratum corneum (outermost skin layer). It is recommended to wash your face thoroughly each evening, followed by timely application of toner and moisturizer to protect the skin, prevent dryness, and delay signs of aging.

② Over-hydration

The stratum corneum contains approximately 20% of the skin’s total water content—and this level is the primary determinant of skin appearance. Daily hydration targets this 20%. When stratum corneum water content falls below 10%, the skin exhibits various signs of dryness; at 20%, the skin appears healthy and plump; at 30%, it looks exceptionally fresh and dewy. However, continued over-hydration beyond 30% causes widening of intercellular spaces, allowing bacteria and impurities to penetrate the skin—potentially triggering acne breakouts or other dermatological issues. Prolonged over-hydration ultimately impairs the skin’s natural repair capacity.
