TeraSerum™ Yerba Mate

The anti-oxidant potential of TeraSerum Yerba Mate was evaluated in-vitro using reconstructed human epidermis (RHE). Reactive Oxygen Species (ROS) were measured following UVA light-induced oxidative stress on samples treated with various concentrations of active vs. control.

RHE tissues were cultured in the presence of TeraSerum Yerba Mate at 0.1% and 1% for 24 hours and subsequently subjected to UVA light (15 J/cm2, 30 min exposure). The fluorescence of the ROS-oxidized product of H2DCFDA, 2’,7’-dichlorofluorescein (DCF) was recorded and relative ROS levels were corrected versus cell viability (measured by the reduction of resazurin to resorufin) to assess the protective effect of the tested sample.

A sharp and statistically significant decrease in ROS levels by 63.1% and 73.2% vs. control was achieved for 0.1% and 1% TeraSerum Yerba Mate treated samples, respectively.
