Barrier Repair
Barrier Repair — the process of restoring the skin's outermost protective layer so it can better retain moisture and defend against irritants. It typically involves replenishing key lipids and reducing the stressors that weakened the barrier in the first place.
Key points
- The skin barrier, or stratum corneum, relies on ceramides, cholesterol, and fatty acids to stay intact and functional.
- Signs of a compromised barrier can include dryness, tightness, redness, stinging, and increased sensitivity.
- Barrier repair often involves gentle cleansing, avoiding over-exfoliation, and using products with barrier-supporting lipids and humectants.
- Ingredients such as ceramides, niacinamide, cholesterol, and fatty acids are commonly used to support barrier recovery.
Frequently asked
How long does it take to repair a damaged skin barrier?
Mild barrier damage may improve within a couple of weeks of gentle care, while more significant disruption can take several weeks or longer. Consistency and pausing harsh actives usually speed recovery.
What ingredients help with barrier repair?
Ceramides, cholesterol, fatty acids, niacinamide, and humectants like glycerin are commonly used to support the barrier. Simplifying your routine while it heals also helps.
