What Collagen Actually Does for Your Skin
Collagen is the most abundant protein in the body and a key component of the skin’s dermis (the deeper layer beneath the surface). Its job is to provide strength, elasticity, and structure — like the springs in a mattress. When collagen is abundant, skin bounces back easily, and looks plump, smooth, and firm. It’s what keeps your cheeks lifted, your jawline defined, and your fine lines from deepening into set-in wrinkles. As it diminishes, the “springs” weaken, leading to sagging, fine lines, and a thinner, more fragile complexion.
The natural decline starts as early as your mid-20s, with about 1% less collagen produced each year. Hormonal shifts, stress, sun damage, and lifestyle habits can speed this up — making early prevention and consistent maintenance essential. Think of it as maintaining the scaffolding of your skin so it stays supported for years to come.
