Hydroxyproline
Ingredient Info
Hydroxyproline is an amino acid that's a key building block of collagen, the protein that gives skin its structure and firmness. In skincare, it's used to support skin barrier function and help maintain skin's structural integrity, particularly when skin has been stressed by sun damage or aging.
Benefits
- Supports collagen structure and skin firmness
- Helps strengthen skin barrier function
- May reduce UV-induced skin damage and inflammation
- Supports skin resilience against environmental stress
Science: Research shows that treatments supporting hydroxyproline levels help restore skin barrier proteins, reduce UV-induced collagen breakdown, and lower inflammation markers in damaged skin. Hydroxyproline serves as a measurable indicator of healthy collagen status and skin barrier integrity.
