Science
Mechanism of Action
This extract operates through a dual mechanism primarily focused on antioxidant and anti-inflammatory pathways. Its high concentration of flavonoids and phenolic acids empowers it to effectively scavenge free radicals and mitigate cellular damage from oxidative stress. Sasa Senanensis Leaf Extract has been shown to inhibit the production of nitric oxide (NO) in activated macrophages, thereby reducing inflammatory responses, redness, and irritation. Furthermore, it supports immune system balance, promotes cellular regeneration, and offers protection against environmental stressors such as pollution and UV radiation. Its conditioning properties contribute to improved skin texture and hydration, with components like chlorophyllin noted for their biological activity.

Key findings
- 01 Cellular studies utilizing Sasa albomarginata extract, a closely related species, demonstrated potent anti-inflammatory effects. At concentrations of 3 mg/ml or lower, it effectively inhibited LPS-induced production of nitric oxide (NO), interleukin-6 (IL-6), and reactive oxygen species (ROS) in mouse monocyte leukemia cells (RAW264.7). Additionally, it suppressed IL-6 production in human monocyte leukemia cells (THP-1) differentiated into macrophages and reduced iNOS, IL-6, and IL-1β expressions. No cytotoxicity was observed below 3 mg/ml.
- 02 Further in vitro research confirmed the antioxidant capacity of Sasa albomarginata extract, showing inhibition of LPS-induced ROS production in RAW264.7 cells at concentrations of 1 and 3 mg/ml.
- 03 Oral administration of Sasa senanensis leaf extracts, at concentrations of 0.05% or higher, significantly suppressed tumor growth in mouse models and extended overall survival, suggesting an immunopotentiation mechanism involving macrophage and NK cell activation.
- 04 In a topical context, exposure to Sasa senanensis extract at concentrations less than 50% resulted in negligible damage to human cultured gingival and periodontal ligament fibroblasts, indicating a substantial safety margin for epithelial tissues.

The Formula
Formulation
Stability
Sasa Senanensis Leaf Extract is often prepared as an 'alkaline extract,' suggesting good stability within alkaline pH ranges. A significant portion of its active compounds, including chlorophyllin, demonstrates water solubility, recoverable from the aqueous layer after extraction.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet published a formal review for Sasa Senanensis Leaf Extract. However, comprehensive oral safety studies for an alkaline extract ('Sasa Health') showed an exceptionally high tolerance, with an oral maximum tolerated dose exceeding 10 g/kg body weight in rats and mice, and no evidence of mutagenicity. A 30-day subchronic feeding study up to 830 mg/kg/day also reported no abnormal symptoms. Topically, concentrations below 50% exhibited minimal damage to human fibroblasts, strongly suggesting a low potential for irritation or sensitization in cosmetic applications.
