Science
Mechanism of Action
This ingredient actively releases ascorbic acid within the skin through esterase enzymes. It acts as a powerful antioxidant, protecting skin from free radical damage induced by UV rays and pollution. APH stimulates Type I collagen production and cellular proliferation, contributing to anti-aging benefits and visible wrinkle reduction. It brightens skin tone by modulating melanin synthesis and inhibiting tyrosinase activity. Additionally, its hyaluronic acid component forms a hydrating film, boosting stratum corneum hydration, supporting barrier function, and facilitating efficient vitamin C delivery to the dermis, while also reducing inflammatory cytokine expression.

The Formula
Formulation
Stability
Ascorbyl Propyl Hyaluronate demonstrates superior thermal stability compared to conventional Ascorbic Acid, resisting degradation from oxidation, light, and heat during manufacturing and storage. It is recommended to maintain temperatures below 40°C during formulation and below 60°C during mixing. For long-term preservation, storage in a refrigerator at 5-15°C, protected from light, or sealed storage at 2-8°C in a cool, dry, light-protected environment is advised. In powder form, it remains stable at -20°C for 3 years, and in solvent at -80°C for 1 year. Its shelf life at room temperature (25-40°C) is 24 months.
Safety
Safety Profile
