The Truth About “Glass Skin” and Barrier Repair: Expert Dermatologists Weigh In
Expert Insight: Dr. Sophia Reynolds, Board-Certified Dermatologist & Skin Health Researcher
“Glass skin isn’t just about layering endless products—it’s about optimizing skin health at a cellular level. The key is a strong, resilient skin barrier.”
What is “Glass Skin”?
The “glass skin” trend, originating from Korean beauty (K-Beauty), refers to skin that appears clear, luminous, and nearly poreless. While many believe it’s purely cosmetic, experts stress the importance of skin barrier health in achieving long-term radiance.
The Science Behind Skin Barrier Repair
1. Ceramides & Lipids: The Unsung Heroes
- The skin barrier is composed of ceramides, fatty acids, and cholesterol, preventing moisture loss and environmental damage.
- Expert View: “Most people compromise their barrier with over-exfoliation. The key is replenishing ceramides to maintain hydration and protection,” says Dr. Reynolds.
- Studies in The Journal of Dermatological Science (2023) show that ceramide-based moisturizers improve barrier function by 60% in 4 weeks.
2. The Role of pH Balance in Glass Skin
- The skin’s optimal pH is between 4.5 and 5.5, and disruptions can lead to redness, sensitivity, and breakouts.
- Expert View: “Avoid alkaline cleansers—use low-pH formulas to maintain the skin’s natural acid mantle,” advises Dr. Reynolds.
3. Hydration vs. Over-Exfoliation
- Overuse of retinoids, acids, and physical exfoliants can weaken the skin’s defenses.
- Best Practice: Use humectants like hyaluronic acid and polyglutamic acid alongside barrier-repairing ingredients like Centella Asiatica and niacinamide.
Final Verdict
“Glass skin isn’t about instant results—it’s about long-term skin resilience. Prioritize repair over trends,” concludes Dr. Reynolds.
