Science
Mechanism of Action
This extract functions primarily as a powerful antioxidant, neutralizing damaging free radicals and mitigating environmental aggressors. Rich in flavonoids and polyphenols, it protects human epidermal keratinocytes against UVB-induced cellular damage by bolstering reactive oxygen species (ROS)-eliminating pathways. Beyond antioxidant defense, it improves skin hydration, elasticity, and fosters barrier regeneration. Its soothing attributes help reduce redness and irritation, promoting a calmer, more uniform complexion. Furthermore, related Nymphaea extracts suggest potential for stimulating epidermal hyaluronic acid synthesis, boosting aquaporin-3 for enhanced hydration, inhibiting melanin production for brightening, and promoting collagen synthesis for anti-aging benefits.

Key findings
- 01 In vitro studies on human epidermal keratinocytes demonstrated that Water Lily Rhizome Extract, at concentrations of 100-400 µg/ml, significantly and dose-dependently reduced UVB-induced apoptotic cell death by bolstering ROS-eliminating pathways.
- 02 Nymphaea tetragona flower extract, when utilized in the synthesis of platinum nanoparticles, exhibited antioxidant and anti-tyrosinase activity in vitro. These nanoparticles (containing the extract) subsequently inhibited tyrosinase activity and UVB-induced melanin biosynthesis in A375 cells, while also promoting collagen I synthesis in HFF-1 cells via the TGF-β/Smad pathway. (Note: These specific brightening and anti-aging results are attributed to the extract embedded within nanoparticles, not the standalone extract at a specified concentration.)

Stability
This water-soluble extract typically employs water or alcohol for extraction, indicating excellent dispersibility in aqueous formulations. While specific optimal pH for the extract's stability is not precisely defined, related enzymatic activity within water lily components suggests a broad pH stability, generally performing well between pH 3 and 9, with optimal activity around pH 7.5.
Safety
Safety Profile
While formal safety assessments by bodies such as CIR, SCCS, or FDA for Hydrolyzed Nymphaea Tetragona Extract are not currently available, the ingredient, along with extracts from related Nymphaea species, is broadly considered safe for topical cosmetic use. A low risk of adverse reactions is observed, though individuals with sensitivities to plants or flowers should exercise caution due to the potential for allergic responses.
