Science
Mechanism of Action
This extract strengthens the skin's natural barrier and promotes cellular regeneration, contributing to overall skin health. Its rich content of vitamin C, lutein, polyphenols, and anthocyanins provides potent antioxidant action, effectively neutralizing free radicals. Additionally, it exhibits anti-inflammatory and broad-spectrum antimicrobial (antibacterial and antifungal) activities, attributed in part to bioactive glucosinolates that hydrolyze into isothiocyanates. These properties enable it to soothe sensitive or irritated skin while enhancing hydration and nourishment. When specifically formulated as the active ingredient Oxygeskin, it targets environmentally induced skin stressors like concentrated blue light, improving skin oxygenation and restoring a healthy, radiant glow.

Dusting Analysis
The established typical use level for Tropaeolum Majus Flower Extract in cosmetics ranges from 0.1% to 0.5%. While higher concentrations have shown efficacy in preclinical animal studies, these are not typical for human cosmetic application. Formulations exceeding 0.5% could be a red flag without specific human safety and efficacy data to support higher concentrations.
The Formula
Formulation
Stability
The extract is commonly supplied in a water and glycerin mixture. Lutein, a key component, is sensitive to light and high temperatures; its stability can be enhanced by freezing and the inclusion of ascorbic acid. Glucosinolates within the plant are susceptible to degradation during extraction, forming beneficial isothiocyanates at neutral pH, whereas nitriles tend to dominate at acidic pH.
Safety
Safety Profile
Tropaeolum Majus Flower Extract has not been specifically reviewed by the CIR or SCCS for cosmetic safety, and the FDA has not classified its cosmetic use. Preclinical topical studies in rats indicated no signs of cytotoxicity or adverse histological, hematological, or biochemical changes. Paula's Choice rates it as 'generally non-irritating', and Incidecoder indicates low irritancy. However, animal studies involving high *internal* doses suggested potential testicular toxicity and other systemic changes; these findings are specific to internal consumption and not directly applicable to typical topical cosmetic use. Due to the absence of specific safety data for topical use during pregnancy, its safety in this context is not confirmed.
