Science
Mechanism of Action
This ingredient functions by supplying bioavailable amino acids and organic acids that reinforce the skin's lipid matrix. It actively neutralizes reactive oxygen species (ROS) and suppresses the production of inflammatory cytokines, effectively mitigating environmental stress and promoting cellular self-regeneration.

Key findings
- 01 In-house data from the Shiseido Global Innovation Center suggests that concentrations between 0.1% and 5.0% significantly boost barrier resilience and skin radiance by empowering the epidermis to self-regenerate.
- 02 Clinical evaluations at 1.0% concentration demonstrate a measurable reduction in facial erythema and a visible improvement in skin elasticity and firmness.

Dusting Analysis
Because biological efficacy is observed as low as 0.1%, it is rarely 'dusted' in high-end formulations, though its presence at 1.0% or higher is preferred for targeting specific inflammatory concerns.
The Formula
Formulation
Stability
Highly stable in aqueous solutions; however, it must be integrated during the cooling phase (below 40°C) to protect heat-sensitive metabolites such as astaxanthin and peptides.
Synergies
- Hyaluronic acid
