Science
Mechanism of Action
Functions as a pro-vitamin C that is metabolized by skin enzymes into active L-ascorbic acid. Inhibits tyrosinase and TRP-2 protein expression to reduce melanin synthesis, acts as an electron-donating antioxidant to neutralize free radicals, and stimulates fibroblast activity to promote collagen production.

Key findings
- 01 2% concentration increased skin brightness (ITA°) by 4% in 20 females after 28 days
- 02 3% showed significant melanin reduction in human epidermis model after 9 days
- 03 0.5% produced 10-fold increase in collagen synthesis in dermal fibroblasts within 24 hours
Transparency
Dusting Analysis
With clinically proven efficacy at 0.5% and strong stability profile, concentrations below 0.1% would likely be insufficient for meaningful skin benefits.
The Formula
Formulation
Stability
Significantly more stable than L-ascorbic acid against light, heat, and oxidation. Enhanced stability with chelating agents like Disodium EDTA and pentylene glycol.
Synergies
- Disodium EDTA
- Pentylene Glycol
Conflicts
