Science

Mechanism of Action

Dunaliella bardawil extract functions primarily through its rich carotenoid content, including beta-carotene, phytoene, and phytofluene, which effectively neutralize free radicals and mitigate oxidative stress. It exhibits significant antiglycation properties by reducing Advanced Glycation End Product (AGE) formation, preserving skin's inherent elasticity. Furthermore, it calms skin inflammation by lowering pro-inflammatory interleukins (IL6 and IL8) and upregulating NRF2, a key antioxidant regulator. The extract also absorbs harmful UVA/UVB radiation, supports cellular regeneration for improved skin tone, and provides hydration through protective film formation and mineral replenishment.

Stability

The carotenoids within Dunaliella bardawil extract are prone to oxidation when exposed to heat, light, and metals due to their highly unsaturated nature. To maintain ingredient integrity, co-formulation with additional antioxidants and packaging that offers light protection are recommended. Notably, its colorless carotenoids (phytoene and phytofluene) exhibit exceptional stability, ensuring sustained antioxidant benefits. The extract generally demonstrates good compatibility with other cosmetic actives.
