Over time, as we grow older, our skin loses its firmness and strength, leading to wrinkles, laxity, facial hollows. Collagen is the skin’s primary structural support — it’s a protein that ensures your skin remains firm and taut. However, as you grow older, your body’s ability to produce new collagen fibers is compromised, drawing your skin downwards due to gravity, thereby leading to a sagging appearance. The continued accumulation of wrinkles, sagging skin, and laxity eventually make you look old.
