Collagen is the most abundant protein in the human body and the main structural component of your skin. But what happens when collagen breaks down—and what can you do about it? In this post, we explore the science behind collagen and what research says about maintaining it through lifestyle and nutrition.
What Is Collagen and Why Is It Essential for Skin?
Collagen types I and III play a critical role in skin strength, elasticity, and hydration. These proteins form a fibrous network in the dermis that supports the skin’s firmness and overall appearance. As we age, our natural collagen levels decrease, contributing to visible signs of aging.

Why Collagen Production Slows Down
Collagen loss occurs due to two main processes: intrinsic aging (natural genetic decline) and extrinsic aging (lifestyle and environmental damage). UV radiation, smoking, high sugar intake, and chronic stress can all accelerate collagen degradation through oxidative stress and inflammation.
According to the American Academy of Dermatology, UV rays are one of the most damaging external factors that break down collagen in the skin.
Key Nutrients for Natural Collagen Support
- Vitamin C – Essential for collagen synthesis
- Proline & Glycine – Amino acids found in bone broth and fish
- Zinc – A cofactor in collagen formation and repair
While collagen supplements are popular, a well-rounded diet plays a far more sustainable role. Read more from Harvard Health on collagen in nutrition.
Habits That Harm Collagen
Smoking, excessive sun exposure, and diets high in refined sugar accelerate the breakdown of collagen. One lesser-known factor is glycation, where sugar molecules bind to collagen and make it stiff and brittle.
According to Cleveland Clinic, high sugar intake can significantly accelerate skin aging and collagen breakdown.
Can Collagen Be Stimulated Naturally?
Natural methods like exfoliation, red light therapy, and consistent skincare routines can mildly stimulate collagen through cellular turnover. Physical stimulation through microneedling has also shown promising results.

When Lifestyle Isn’t Enough
While nutrition and sun protection go a long way, some patients choose to explore in-office treatments that support collagen remodeling. For example, microneedling treatments at our Torrance location use controlled injury to stimulate collagen production over time.
For patients with volume loss or deeper wrinkles, collagen-stimulating fillers such as Radiesse may be considered, under professional guidance.
Conclusion
Collagen loss is a natural part of aging, but there’s a lot you can do to protect what you have. Focus on the right nutrients, reduce environmental damage, and talk to a licensed provider if you’re curious about clinical options.
