Science
Mechanism of Action
It functions as a multi-dimensional 'urban shield' by inhibiting the physical adhesion of carbon micro-particles to the skin's surface and reducing the synthesis of Reactive Oxygen Species (ROS). By reinforcing the skin's innate biological defense systems, it limits the penetration of lead and other pollutants into the deeper epidermal layers, preventing lipid peroxidation and preserving cellular integrity.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 In vivo trials at 0.5% demonstrated a significant reduction in carbon particle adhesion and a decrease in Malondialdehyde (MDA) levels, a marker for lipid peroxidation, under exposure to heavy metals and smoke.
- 02 In vitro testing confirmed a reduction in ROS production and a measurable decrease in the dermal penetration of lead and fine particulate matter.
Transparency
Dusting Analysis
Because it is an expensive plant cell culture, many brands list it at trace amounts for marketing claims. For measurable anti-pollution and antioxidant efficacy, it should be formulated at a minimum of 0.5%.
The Formula
Formulation
Stability
Thermolabile; must be incorporated during the cooling phase (below 40°C) to maintain the viability of the cellular components.
Synergies
- Vitamin C
- Niacinamide
- Chelating agents
Conflicts
- Strong oxidizing agents
- High-temperature processing
Safety
Safety Profile
Generally recognized as safe in cosmetic use. The 0.5% max concentration refers to the tested clinical benchmark rather than a safety ceiling.
