Science
Mechanism of Action
Hibiscus Cannabinus Stem Powder exerts its beneficial effects through several key mechanisms. It acts as a potent antioxidant, neutralizing free radicals and protecting skin cells from oxidative damage. Its anti-inflammatory properties are demonstrated by inhibiting various inflammatory pathways, including lipoxygenase, COX, and MMPs, and reducing the expression of pro-inflammatory cytokines like IL-1β and TNF-α. For anti-aging, it boosts collagen synthesis in fibroblasts and inhibits elastin degradation, addressing fine lines and wrinkles. In terms of skin tone, it inhibits tyrosinase activity and melanin production, leading to a reduction in dark spots and hyperpigmentation. Furthermore, it supports skin barrier function by enhancing stratum corneum conversion and restoring vital barrier proteins such as filaggrin and involucrin.

Key findings
- 01 Cosmetic compositions incorporating kenaf plant extract (including stem components) have been shown to reduce fine lines and wrinkles, alleviate skin rashes, dryness, sensitivity, and itchiness. They also improve skin tone, diminish dark spots, and reduce inflammation. These compositions demonstrate inhibition of skin tyrosinase activity, B16 cell melanin production, and elastin activity, while promoting collagen secretion and inhibiting skin oxidation.
- 02 Studies on kenaf leaf and seed extracts, applied at concentrations from 62.5 to 1000 µg/mL, revealed significant antioxidant, anticancer, and antibacterial properties, generally exhibiting non-toxicity to mouse embryonic fibroblast cells, with only minor toxicity noted for n-hexane extracts at the highest concentration (0.1%).

Stability
Kenaf stem components demonstrate enhanced stability in acidic environments compared to alkaline conditions. Water is identified as an optimal solvent for extracting its functional, highly antioxidant compounds.
Safety
Safety Profile
Official CIR, SCCS, or FDA safety assessments specifically for Hibiscus Cannabinus Stem Powder are not available. However, broader studies on Kenaf extracts (including stem components) indicate general non-toxicity. Extracts have been observed as non-toxic to mouse embryonic fibroblast cells, although certain n-hexane extracts showed slight toxicity at high concentrations (1000 µg/mL or 0.1%).
