There’s a noticeable shift happening in skincare, and it’s less about fixing damage and more about staying ahead of it. It is all about collagen banking, a concept that is steadily gaining traction among dermatologists and skincare enthusiasts alike. At its core, it’s about preserving what your skin already has before time begins to take it away. Collagen, derived from the Greek word kolla meaning “glue,” is the structural protein that keeps your skin firm, plump, and youthful. It forms the foundation not just for skin, but also for hair, nails, bones, and connective tissues. However, as dermatology experts point out, collagen production begins to decline as early as your mid-20s, by about 1 to 1.5 per cent each year. Over time, this gradual loss manifests as fine lines, sagging, and dullness.
