Collagen
Ingredient Info
Collagen is a structural protein that forms the main support framework of your skin. In topical skincare products, collagen molecules are too large to penetrate the skin barrier, so they primarily work by forming a moisturizing layer on the surface and cannot directly replace the collagen your skin loses with age.
Benefits
- Temporary surface hydration and plumping
- Smoother skin texture appearance
- Film-forming effect that can reduce water loss
Potential concerns
- Cannot penetrate skin to rebuild internal collagen
- May feel heavy or occlusive for some skin types
- Topical collagen does not address the root cause of collagen loss from aging
Science: Research shows that dermal collagen naturally decreases with age due to increased enzyme breakdown and impaired collagen production by fibroblasts. While topical collagen is safe and well-tolerated, its large molecular size prevents it from being absorbed into deeper skin layers, meaning it functions primarily as a humectant rather than a collagen-rebuilding agent. Ingredients like vitamin C derivatives are scientifically shown to stimulate the skin's own collagen production more effectively than topical collagen itself.
