Cell Fusion C Slow Aging Duo is a two-step slow-aging routine that combines the Collagen PDRN Ampoule and Glass Skin Collagen Mask (5 sheets) to support skin resilience, firmness, and deep hydration. Why It Works Visible signs of aging—loss of firmness, dehydration, and fine lines—come from weakened skin elasticity and moisture depletion. This duo strengthens skin from both angles. Step 1: Rebuild + Firm with Collagen PDRN Ampoule PDRN and peptides help support skin renewal, improve texture, and restore youthful bounce. Step 2: Hydrate + Plump with Glass Skin Collagen Mask A concentrated collagen essence mask boosts glow, deeply hydrates, and leaves skin smooth and radiant. A simple, effective pairing for smoother, firmer, slow-aging results.
