Here's how antioxidants specifically contribute to collagen preservation.

Neutralising Free Radicals

Antioxidants directly neutralise free radicals, which are highly reactive molecules that can damage collagen fibres. https://pubmed.ncbi.nlm.nih.gov/35050544/

By scavenging these harmful molecules, antioxidants prevent them from breaking down the collagen structure.

Reducing Oxidative Stress

Antioxidants help reduce overall oxidative stress in the skin and body. A study showed that a product with high antioxidant ability could block 99.0% of oxidation https://pubmed.ncbi.nlm.nih.gov/35050544/

Inhibiting Collagen-Degrading Enzymes

Some antioxidants can inhibit enzymes that break down collagen. For example, a study found that a formula containing antioxidants inhibited collagenase (an enzyme that degrades collagen) by 61.8% https://pubmed.ncbi.nlm.nih.gov/35050544/ This inhibition helps preserve existing collagen in the skin.

Protecting Against Environmental Damage

Antioxidants shield collagen from environmental factors that can accelerate its breakdown. Research has shown that antioxidants can reduce oxidative stress induced by pollution by 48.94% and by a combination of pollution and UVA radiation by 96.28% https://pubmed.ncbi.nlm.nih.gov/35050544/

Supporting Collagen Synthesis

While primarily known for their protective effects, some antioxidants also support collagen production. Vitamin C, a powerful antioxidant, is essential for collagen synthesis. It acts as a cofactor for enzymes involved in collagen formation and promotes proper folding of the collagen triple-helix structure. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6204628/

Preserving Skin Structure

By protecting collagen and other structural proteins, antioxidants help maintain overall skin health and structure. This includes preserving elastin, another important protein for skin elasticity. A study found that a formulation with antioxidants and a specific form of vitamin C showed good conservation of healthy elastin https://onlinelibrary.wiley.com/doi/full/10.1111/jocd.15999

Antioxidants are vital for collagen preservation. They protect existing collagen from damage, inhibit its breakdown, and support its synthesis, ultimately contributing to healthier, more youthful-looking skin.
