Which Collagen Is Best for Sagging Skin?

If you're noticing your skin losing firmness, you're not alone—and the answer might lie in the right type of collagen. As we age, our body’s natural collagen production slows down, especially Type I collagen, which plays a starring role in keeping skin strong, elastic, and youthful.

Type I collagen is the most abundant form in the human body, making up about 90% of your total collagen. It’s the primary structural protein in skin, bones, hair, and nails, giving them strength and resilience. When it comes to sagging skin, Type I is the go-to. It helps rebuild the skin’s foundation, improving elasticity and reducing the appearance of fine lines and wrinkles over time.

While there are over a dozen types of collagen, only a few—like Type I, II, and III—are commonly found in supplements. Type II is more associated with joint health, and Type III supports muscles and organs. But for visible skin benefits, especially firmness and hydration, Type I stands out.

The best collagen supplements for skin often combine Type I with Type III for a more comprehensive effect. Still, experts agree that prioritizing Type I delivers the most noticeable results when targeting sagging or aging skin. These supplements are typically sourced from bovine (cow), marine (fish), or chicken collagen, with marine collagen being particularly rich in Type I and highly bioavailable.

Beyond supplements, supporting your body’s natural collagen production with vitamin C, a healthy diet, and sun protection can enhance results. But if you’re looking for a targeted boost, choosing a supplement rich in Type I collagen is a smart first step toward firmer, more resilient skin.
