Skincare Hydrolyzed Silk Fibroin High Bioactivity Silk Protein Fibroin

1. Product Description

• Silk Fibroin is a high-purity natural macromolecular active protein extracted from premium mature silk cocoons, classified as a high-end bionic skincare and medical aesthetic raw material. Its amino acid composition is highly consistent with human skin, delivering outstanding skin affinity and superior transdermal penetration. Unlike traditional single-effect moisturizing ingredients, silk fibroin integrates multiple core effects including deep nourishing hydration, skin barrier repair, texture smoothing and anti-aging rejuvenation. It effectively improves common skin problems such as dry roughness, dull complexion, shallow dry lines and fragile skin texture. It forms a lightweight, breathable and non-greasy nourishing protective film on the skin surface, locking moisture for a long time. With mild nature and stable activity, it is widely applied in daily delicate skincare and high-end anti-aging formula systems, serving as a classic natural gentle active raw material in the global beauty industry.

2. Product Features

• High Skin Bionic Homology: Rich in multiple essential amino acids highly matched with human skin tissue, the molecular structure is easy to identify and absorb by basal skin cells. It fits skin physiology perfectly without rejection or irritation, realizing genuine bionic skin nourishing and repair.
• Dual Film-Forming & Moisturizing Property: Possesses excellent breathable film-forming ability. It forms a flexible protective layer on the skin surface to lock internal moisture and resist external dry stimulation, improving dry flaky skin while maintaining skin breathability, non-sticky and non-greasy.
• Mild & High Safety: Derived from natural silk cocoon purification, free of hormones, alcohol and irritating additives. With low molecular burden and ultra-mild properties, it adapts to all skin types, especially dry, sensitive and fragile skin for long-term safe maintenance.
• Multi-Dimensional Skin Improvement: It not only provides surface moisturizing care, but also acts on basal skin metabolism, repairing damaged stratum corneum, smoothing rough texture, fading dry lines and brightening dull skin tone with comprehensive skincare effects.
• Stable Formula Adaptability: Features stable physical and chemical properties, not easy to oxidize, deactivate or stratify. It has strong compatibility with aqueous formulas, essence systems and anti-aging ingredients, suitable for diversified skincare product development and mass production.

3. Technical Principle

• Bionic Amino Acid Nutrient Supplementation: Silk fibroin contains abundant natural active amino acids consistent with human skin. The low-molecular active structure efficiently penetrates epidermal gaps, directly supplements skin basal nutrients, improves insufficient intracellular moisture and nutrition, and relieves persistent dry and tight skin state.
• Breathable Protective Film Locking Mechanism: Active protein molecules form a uniform and flexible breathable protective film on the skin surface. It effectively locks subcutaneous moisture to reduce water evaporation, isolates dry air and external minor irritation, and improves rough, flaky and peeling skin texture.
• Skin Basal Metabolism Activation: Continuously activates the metabolic vitality of skin basal cells and microcirculation, accelerates nutrient transportation and waste metabolism, enhances skin self-renewal ability, and fundamentally improves dull and tired skin condition.
• Epidermal Barrier Reconstruction: Promotes the repair and regeneration of damaged stratum corneum, supplements intercellular nutrients, reorganizes loose skin tissue structure, builds a smooth, delicate and tight skin barrier, and enhances skin defense ability.
• Dry Line Fading & Translucent Rejuvenation: Improves fine dry lines and shallow wrinkles caused by long-term water loss and skin aging, evens out skin texture, continuously brightens yellowish and dull skin, and restores skin delicate, translucent and elastic youthful state.
