Products Description
This aqueous formulation is sodium salt of hyaluronic acid, a linear glycosaminoglycan naturally existing in human dermis extracellular matrix, produced via controlled microbial fermentation and standardized aqueous dilution for cosmetic formulation use only.
- Hydration Mechanism: Its polyhydroxyl polysaccharide molecular structure combines free water molecules via hydrogen bonding; single molecule can bind water up to 800–1000 times its own molecular weight, reducing transepidermal water loss (TEWL) by forming semi-permeable hydrophilic film on stratum corneum without blocking skin gas exchange.
- Skin Repair Mechanism: Medium & low-molecular-weight fractions penetrate epidermis intercellular space, upregulate fibroblast viability in vitro to promote endogenous collagen & elastin biosynthesis; high-molecular-weight component stabilizes intercellular lipid arrangement to repair impaired skin barrier structure caused by environmental irritation.
- Anti-fine Line Mechanism: Supplement extracellular matrix HA content to fill inter-fiber gaps between collagen bundles, improve dermal tissue compactness mechanically to smooth superficial fine lines induced by chronic dehydration, no instant physical swelling effect.
- Anti-inflammatory Mechanism: Modulate cutaneous inflammatory cytokine secretion to alleviate mild inflammatory response of sensitive epidermis via inhibiting excessive free radical accumulation in skin tissue.
