Commonly known as Night-blooming Jasmine, this botanical distillate serves as a multifunctional aqueous tonic rich in bioactive secondary metabolites. It provides a dual-action approach to skincare by neutralizing oxidative stress while maintaining a balanced skin microbiome.

Science

The water utilizes a complex matrix of flavonoids like quercetin and kaempferol to quench reactive oxygen species (ROS) and provide photo-protective benefits. Additionally, its natural concentration of saponins and alkaloids exerts an anti-inflammatory effect by modulating pro-inflammatory cytokines, while volatile aromatic compounds like linalool offer skin-soothing properties.
