Science
Mechanism of Action
This ingredient functions as both a humectant and a structural biomimetic. The presence of calcium ions improves the skin's ability to absorb collagen peptides, while on the surface, it creates a breathable, moisture-binding film. At a cellular level, it helps replenish intracellular calcium levels and supports the dermal matrix, effectively smoothing fine lines by reinforcing the skin's connective scaffold.

Key findings
- 01 Demonstrated significant increases in skin hydration and improved surface texture through film-forming capabilities.
- 02 Calcium-bound peptides showed increased incorporation into skin and nail structures, facilitating rejuvenation and reducing cellular damage.

Dusting Analysis
Because collagen is a high-profile marketing term, brands often include it at trace levels (<0.1%) purely for label claims. However, clinical data suggests a minimum of 0.2% is required for basic hydration, while therapeutic rejuvenation benefits typically require concentrations above 0.5%.
The Formula
Formulation
Stability
Highly resilient in electrolyte-rich environments. Maximum water-binding capacity is achieved at a slightly acidic pH of approximately 5.0.
