Science

Mechanism of Action

This extract exerts its benefits through several well-defined mechanisms. It delivers potent antioxidant activity by neutralizing free radicals and inhibiting oxidation, thereby effectively preventing oxidative stress. Anti-inflammatory effects are observed through the attenuation of MAPK signaling pathways, leading to a reduction in sUV-induced COX-2 expression and cytokine production. For complexion brightening, the extract suppresses tyrosinase activity, which is crucial in preventing excess melanin synthesis. Furthermore, it actively promotes skin elasticity and reduces wrinkle appearance by inhibiting matrix metalloproteinase-1 (MMP-1) activity, an enzyme involved in collagen degradation. The extract also functions as a humectant and skin conditioner, contributing to overall skin hydration and barrier function.

Stability

Components of Rosa chinensis flower can be effectively extracted into both aqueous (polar solvents such as water, ethanol, glycols) and oil phases, indicating a versatile chemical profile with both water-soluble and oil-soluble compounds. Oil extracts of rose may require preservation under nitrogen inerting to mitigate sensitivity to oxidation and maintain stability.
