Your skin barrier is your body’s natural shield, protecting against pollution, bacteria, and moisture loss. When strong, it locks in hydration and keeps irritants at bay, ensuring a healthy, radiant complexion. When weakened, it can lead to dryness, irritation, and breakouts.
What is the Skin Barrier?
The skin barrier is the outermost layer of your skin, also known as the stratum corneum. It consists of lipids and skin cells, forming a protective shield that:
- Prevents water loss, keeping your skin hydrated
- Shields against external aggressors like pollutants, UV rays, and bacteria
- Minimises irritation by maintaining a balanced, healthy skin environment
When damaged, the skin barrier becomes weakened and compromised, leading to:
- Dehydration and dullness
- Increased sensitivity and redness
- Breakouts and inflammation
- Rough or uneven skin texture
To restore and strengthen your skin, incorporate barrier-repairing ingredients into your routine.
