!What Is Collagen and Why Is It 70% of Your Skin? - SUSHENAH scientific illustration Collagen is the structural protein that gives your skin tensile strength—and it represents 70% of your skin's dry weight. According to research in Andrews' Diseases of the Skin, collagen is "a major stress-resistant material of the skin" found primarily in the dermis layer. That's not a small component. That's the majority of your skin. Here's the part that changes everything. "Collagen fibers exist in a constant state of flux, being degraded by proteolytic enzymes called collagenases and replaced by new fibers." Your skin isn't just losing collagen. It's constantly breaking down old collagen and building new collagen. This isn't a one-way decline. It's an ongoing rebuilding process. Real change takes time. But supporting this natural rebuilding is what collagen care is actually about—not adding collagen from outside, but helping your skin make its own.
