Does a 70-Year-Old Still Produce Collagen?

Yes, a 70-year-old still produces collagen—but significantly less than in younger years. As we age, the body’s ability to generate new collagen declines steadily. By the time someone reaches their seventh decade, this slowdown becomes quite noticeable, especially in the skin and joints.

Collagen is the scaffolding of our connective tissues, giving skin its firmness and elasticity while supporting cartilage, tendons, and bones. Unfortunately, aging takes a toll. Starting in our mid-20s, collagen production decreases by about 1% per year. By age 70, this cumulative loss leads to visible changes: thinner skin, deeper wrinkles, and reduced wound healing capacity.

The decline isn’t limited to collagen alone. The skin also produces fewer proteoglycans and glycosaminoglycans, like hyaluronic acid—molecules crucial for retaining moisture and volume. This contributes to dryness and sagging. Similarly, cartilage in joints becomes less resilient due to reduced collagen and glycosaminoglycan content, which may worsen stiffness or discomfort.

While we can’t stop time, lifestyle choices can influence how gracefully this process unfolds. A diet rich in vitamin C, amino acids, and antioxidants supports residual collagen production. Sun protection remains one of the most effective ways to preserve existing collagen, as UV exposure accelerates its breakdown. Some also turn to collagen supplements or topical retinoids, though results vary from person to person.

The truth is, aging skin isn’t a flaw—it’s a sign of a life lived. But understanding the science helps us care for it better. Even at 70, the body is still working hard to renew itself—just a little more quietly than before.
