Application
1
Pharmaceuticals & Joint Health
- Adjunct Therapy for Osteoarthritis: Acts as a precursor for cartilage matrix, promoting glycosaminoglycan synthesis. It helps repair damaged cartilage, reduce joint friction and pain, and alleviate symptoms of osteoarthritis and rheumatoid arthritis.
- Anti-inflammatory & Immunomodulation: Inhibits inflammatory cytokines such as IL-1 and TNF-α, regulates glycoprotein synthesis in immune cells, and enhances overall immunity.
2
Cosmetics & Oral Beauty
- Moisturizing & Anti-aging: Stimulates the skin to synthesize hyaluronic acid, improves the water-retention capacity of the stratum corneum, reduces dry and fine lines, and enhances skin elasticity and fullness.
- Barrier Repair: Maintains the integrity of the skin barrier, promotes the repair of damaged skin, and soothes sensitivity.
- Whitening & Spot Reduction: Inhibits melanin production, improving dullness, acne marks, and pigmentation.
- Applicable Forms: Serums, creams, face masks, and oral beauty drinks.
