What Is the Skin Barrier & Why It Matters
Your skin barrier is your first line of defense. When it’s healthy, your skin stays hydrated, calm, and resilient. When it’s damaged, you may experience:
- Redness and sensitivity
- Breakouts and irritation
- Dryness and tightness
- Stinging when applying products
Common Causes of a Damaged Skin Barrier
- Over-exfoliation
- Using too many active ingredients
- Harsh cleansers
- Environmental stress (sun, pollution)
Repairing the barrier requires gentle, nourishing skincare.
Best Ingredients for Barrier Repair
- Niacinamide – strengthens the barrier and reduces inflammation
- Ceramides & lipids – restore moisture balance
- Soothing creams – reduce sensitivity and prevent water loss
