Your skin loses 1% of collagen every year after 25. By 50, almost half your collagen is gone. Western collagen creams cannot fix this — their molecules are 600x too big to penetrate your skin. Korean researchers cracked the code: 120-Dalton collagen — small enough to slip past the skin barrier and reach the fibroblasts that actually produce collagen. Combined with 3,000-year-old silk medicine refined into a modern bio-silk matrix. The result? Structural rebuilding from within — not just surface hydration that washes off.
