@sallsters: After we turn 25, our collagen levels start to decline by about 1% every year. That’s why fine lines, dark circles, and dull skin creep up. But when you drink collagen daily, you’re literally replenishing what your body stops making—think plumper skin, stronger hair + nails, and that glow people assume is “genetics.” #crushedtonic #protein #Science #collagen #korean
