When you hear the term “glass skin,” what comes to mind? Probably a flawless and luminous complexion that looks like it’s lit from within.
Originally popularised by Korean beauty trends, the concept of glass skin has now become a global phenomenon. But as a dermatologist, I want to break down the science behind this look — because it’s not about perfection or filters, but about achieving healthy, hydrated, and resilient skin.
What Is Glass Skin, Really?
Glass skin refers to skin that looks exceptionally smooth, clear, and radiant, with no visible pores or roughness. It’s not a “one product fix” — it’s the result of a consistent skincare routine that focuses on strengthening the skin barrier, improving hydration, and maintaining even tone.The foundation of glass skin is skin health, not makeup tricks.
The Science Behind the Glow:
1. Hydration at Cellular Level:
- Hydrated skin reflects light better, giving it that natural dewy glow.
- Ingredients like hyaluronic acid act as humectants, pulling water into the skin’s upper layers.
2. Healthy Skin Barrier:
- The outermost layer, the stratum corneum, protects against pollutants, microbes, and allergens.
- Over-exfoliating or harsh routines damage this barrier, causing dullness and irritation.
3. Balanced Exfoliation:
- Gentle use of AHAs, BHAs, or PHAs helps remove dead skin cells, unclog pores, and reveal fresh, even-toned skin.
- Physical scrubs should be used sparingly to avoid microtears.
4. UV Protection :
- Sun damage is the single biggest reason skin loses clarity.
- Broad-spectrum sunscreen prevents pigmentation, premature ageing, and breakdown of collagen
Dermatologist-Approved Routine for Glass Skin
Step 1: Double CleansingStart with an oil-based cleanser to dissolve sunscreen and makeup, followed by a gentle foaming cleanser to remove sweat and dirt. This ensures a clean base without stripping natural oils.
Step 2: Hydrating Toner or EssenceInstead of harsh, alcohol-based toners, choose hydrating essences with glycerin, panthenol, or hyaluronic acid.
Step 3: Serums for BrighteningVitamin C (ascorbic acid) is a potent antioxidant that helps fade pigmentation and boosts collagen. Niacinamide reduces pore size and improves skin tone.
Step 4: Barrier StrengtheningA good moisturizer with ceramides, cholesterol, and fatty acids helps repair the barrier and prevent transepidermal water loss.
Step 5: Daily SunscreenSPF 30+ is non-negotiable. Apply generously and reapply every 2–3 hours if outdoors.
