Recombinant Human-Derived Sericin: The ‘Biological Shield’ for Reconstructing the Skin Barrier
As an innovative ingredient in skin repair, recombinant human-derived sericin precisely replicates the natural sericin sequence of the human body through genetic engineering technology. It functions through a dual mechanism of ‘biomimetic supplementation + intelligent moisturisation,’ making it a core ingredient for the care of dry and sensitive skin. Its unique amino acid structure directly supplements sericin deficiencies caused by genetic defects or environmental damage.
Core Benefits and Technical Advantages
1. Barrier Strengthening System: It accounts for 30% of the natural moisturising factors (NMF) produced, promotes ceramide synthesis in the stratum corneum, and reduces transepidermal water loss;
2. Long-lasting Moisturising Network: Rich in amino acids such as histidine and arginine, which can bind 150 times their weight in water, forming a dynamic moisture-locking film, with a 65% increase in continuous moisturising efficiency over 8 hours;
3. Anti-inflammatory synergistic effect: Inhibits the release of inflammatory factors such as IL-6 and TNF-α (reducing them by 71%). When used in combination with ceramides, the redness area in sensitive skin is reduced by 63%.
Diverse application scenarios
- Sensitive skin repair cream: Recommended addition rate of 1%-3%, quickly alleviating dryness, itching, and stinging;
- Baby care products: Formulated with a gentle formula, passed human patch testing, effectively prevents diaper rash;
- Post-aesthetic surgery care: Added to masks to accelerate epidermal layer repair after laser procedures;
- Autumn/winter moisturising series: Blended with hyaluronic acid to enhance skin hydration and elasticity.
