Science
Mechanism of Action
This extract functions as a potent natural antioxidant, demonstrating strong DPPH free radical scavenging capacity and reducing intracellular reactive oxygen species (ROS) production. It exerts anti-inflammatory effects by decreasing the mRNA expression of various inflammatory cytokines (e.g., IL-1β, IL-4, IL-6, IL-8, IL-13) and down-regulating NF-κB and MAPKs activation, while also inhibiting the NLRP-3 inflammasome. Furthermore, it supports skin barrier restoration through enhanced synthesis of filaggrin and involucrin proteins. For anti-hyperpigmentation, it inhibits skin tyrosinase activity and melanin production in B16 cells. Its anti-aging properties are attributed to inhibiting collagenase, elastase, skin lipoxygenase, COX, MMP-1, and MMP-3 activities, alongside promoting collagen secretion.

Key findings
- 01 Clinical application in this range demonstrated potential for wrinkle reduction, skin whitening, sunscreen effects, and overall skin care. Compositions were found to inhibit skin tyrosinase activity, B16 cell melanin production, elastin activity, TNF-α secretion, and skin oxidation, while promoting collagen secretion. Inhibition of skin lipoxygenase, COX, MMP-1, and MMP-3 activity was also observed, proving effective for fine lines/wrinkles, skin rashes, dry/sensitive/itchy skin, uneven skin tone/dark spots, and skin inflammation.
- 02 This specific formulation showcased antioxidant, antityrosinase, and anti-aging benefits through the inhibition of collagenase and elastase. It also highly suppressed cellular tyrosinase activity and melanin content in B16F10 cells.

Dusting Analysis
There is no available data to suggest that Hibiscus Cannabinus Extract is commonly 'dusted' or used at sub-efficacious concentrations for marketing purposes. Efficacious concentrations range from 0.001% to 20.0%.
The Formula
Formulation
Stability
The extract's versatility allows for dissolution in various solvents including water, alcohols (methanol, ethanol, propanol, butanol), glycol, and oil, depending on the desired active compounds and extract type. Kenaf seed oil, often co-extracted or co-formulated, can enhance the stability of vitamin E in cosmetic formulations.
Synergies
- Vitamin E (improved stability when co-formulated with Kenaf seed oil)
Safety
Safety Profile
Hibiscus cannabinus oil demonstrated no toxicity up to 5000 mg/kg body weight in oral acute toxicity tests in rats. Ethanol extracts of kenaf root and all extracts of leaves and seeds were observed as non-toxic in NIH3T3 cell studies, indicating a generally good safety profile.
