Science
Mechanism of Action
This ingredient functions by leveraging its diverse bioactive compounds, including vitamins C and B1, carotenoids (such as beta-carotene, lutein, and zeaxanthin), polyphenols, and flavonoids. These components provide significant antioxidant protection, mitigating damage from oxidative stress and UV exposure. It actively promotes collagen synthesis, improves microcirculation, and contributes to enhanced skin elasticity. Additionally, it serves as a skin conditioner, humectant, and skin protectant, while potentially regulating sebum production and reducing inflammation to support skin regeneration and revitalization.

Stability
Pumpkin juice naturally exhibits a pH range of approximately 5.09 to 6.13, varying by cultivar. Formulations incorporating Cucurbita maxima fruit extracts, such as emulgels, have shown stability when maintained at a pH around 5. The ingredient is typically prepared through fruit squeezing and filtration, often concentrated in a blend of water, glycerin, and preservatives for enhanced stability.
Safety
Safety Profile
