Ceramide VE Liposomes: A Nanoscale Repair System for Building the Skin Barrier
In the field of cosmetic ingredients, Ceramide VE Liposomes stand out for their dual characteristics of ‘biomimetic barrier + precise delivery,’ making them a core solution for addressing skin issues such as dryness, sensitivity, and ageing. These nanoscale vesicles (particle size 80–120 nm), composed of ceramides, vitamin E, and phospholipids, mimic the skin's lipid bilayer structure to achieve efficient penetration and sustained release of repairing ingredients, redefining the technical standards of barrier care.
Core Components and Mechanism of Action
1. Ceramides: The Foundation of Barrier Reconstruction
As the core component of the stratum corneum lipids (accounting for 40-50%), the ceramide NP, AP, and EOP blend directly replenishes lost lipids, repairs the intercellular ‘cement’ structure, reduces transepidermal water loss (TEWL) by 58%, and achieves a barrier repair rate of 91% within 28 days.
2. Vitamin E: The Golden Partner for Antioxidant Repair
Alpha-tocopherol (VE) embedded in the hydrophobic layer of liposomes has a free radical scavenging capacity of 92%, while also inhibiting matrix metalloproteinase (MMP-1) activity to reduce collagen degradation. When synergised with ceramides, it can increase dermal antioxidant enzyme (SOD) activity by 45%.
3. Liposome Delivery System: A Revolution in Efficiency
The phospholipid bilayer structure has 99% skin compatibility. Through ‘membrane fusion technology,’ it directly delivers ingredients to the deep layers of the stratum corneum. Ceramide transdermal absorption rate is 300% higher than traditional creams, and VE concentration in the dermis is five times that of conventional formulations.
Diverse Application Scenarios and Formulation Compatibility
- Sensitive skin repair: Recommended addition rate of 3-5%, used in serums or masks, can quickly alleviate symptoms of hormone-dependent dermatitis. When combined with bisabolol, itchiness scores decrease from 7.2 to 2.1;
- Anti-ageing and anti-dryness: 2% added to face cream, ceramides promote collagen synthesis (type I collagen increased by 39%), and vitamin E inhibits photoageing, reducing fine lines around the eyes by 25% within 8 weeks;
- Scalp Barrier Care: Liposome-encapsulated ceramides penetrate to the root of hair follicles, repairing the scalp's lipid barrier, with a 89% reduction in dandruff. Suitable for dry scalps and post-permanent hair care.
