A damaged skin barrier occurs when the outer layer of the skin is weakened, leading to dryness, sensitivity, and irritation.
Common causes:
- Over-exfoliation
- Harsh skincare products
- Environmental stress
To repair the skin barrier:
- Use gentle cleansers
- Apply hydrating serums
- Avoid strong actives temporarily
- Use ceramide-based moisturizers
Korean skincare is widely used for barrier repair due to its gentle formulations.
