Description
Ceramide Liquid, 20%
Ceramide LC S-20 is a ceramide ingredient in a Liquid Crystal Structure form with a 20% active concentration, developed using advanced liquid crystal technology by Macrocare, South Korea. It is designed to mimic the natural structure of ceramides found in the outermost layer of human skin.
This product is formulated to strengthen the skin barrier, reduce transepidermal water loss (TEWL), and enhance cell adhesion in the stratum corneum. It also helps deliver long-lasting moisture while providing a smooth, non-greasy feel.
Ideal for individuals with dry or sensitive skin, as well as those who need effective skin repair and protection from external aggressors.

Ceramide LC S-20 stands out with its Liquid Crystal Technology, which mimics the multi-lamellar structure of natural ceramides in human skin. This technology allows it to dissolve easily in water while maintaining a micro liquid crystal structure when incorporated into cosmetic formulations.
Ceramides are the most essential lipids in the outermost layer of the skin, accounting for 40–65% of total skin lipids. They play a crucial role in forming the skin’s protective barrier. With a high ceramide concentration of 20%, this ingredient helps replenish depleted ceramides in the skin, reduce transepidermal water loss (TEWL), and reinforce the skin barrier. It also provides a smooth and soft texture without the greasiness typical of silicone-based products.
With a melting point of 50–55°C and a pH of 7.0–7.5, close to that of the skin, Ceramide LC S-20 is well-suited for formulating rich moisturizers and intensive skin-repair products.
Mechanism of Action and Benefits
Active Ingredient: Ceramide PC-108 (Ceramide)
Structure and Composition:
Ceramide is a lipid with a unique structure, consisting of a long-chain fatty acid linked to sphingosine. In this product, ceramide is arranged in a Liquid Crystal Structure along with other components such as cholesterol, cholesteryl isostearate, squalane, and fatty alcohols to mimic the multi-lamellar structure of lipids in the outermost layer (stratum corneum) of human skin.
Mechanism of Action:
- Enhancement of Skin Barrier Function
Ceramide in Liquid Crystal form fills the gaps between skin cells in the outermost layer, acting like “cement” that holds the “bricks” (skin cells) together, forming a strong protective barrier that prevents external irritants and foreign substances from penetrating the skin. - Reduction of Trans-Epidermal Water Loss (TEWL)
The multi-layered Liquid Crystal structure helps block water evaporation from the skin, maintaining long-lasting hydration and reducing dryness and flakiness. - Increased Cohesion of the Upper Epidermis
Ceramide strengthens the adhesion between skin cells, resulting in a tighter, smoother skin structure, reducing roughness and improving overall skin texture. - Stability and Maintenance of Micro Liquid Crystal Structure
When incorporated into cosmetic products, Liquid Crystal ceramide retains its Micro Liquid Crystal structure, offering high stability without affecting emulsion particles or product viscosity, ensuring effective performance. - Special Sensory Experience (Non-Greasy, Lubricating Feeling)
Unlike silicones, this form of ceramide provides a smooth, soft, non-greasy texture, absorbs well, and leaves the skin feeling hydrated.
Benefits and Applications:
-
Strengthens and repairs weakened skin barrier
-
Increases skin hydration and reduces water loss
-
Protects skin from external irritants and pollution
-
Smooths and softens skin texture
-
Suitable for creams for dry, sensitive, or skin-repair products
-
Easy to formulate, water-dispersible
Research Study
Research from the Department of Dermatology, University of California, San Francisco, investigated the role of ceramide in skin barrier function and found that ceramide is the most critical component of lipids in the outermost layer of the skin, accounting for 40–65% of total lipids. The study showed that individuals with dry, sensitive, or inflamed skin often have lower ceramide levels in their skin. Applying ceramide-containing products significantly reduced trans-epidermal water loss (TEWL), increased skin hydration, and improved the structure of the skin barrier. Additionally, ceramide in Lamellar Structure (multi-layered structure) was found to be more effective than regular ceramide in restoring and protecting the skin.
