What Is Sasa Senanensis Leaf Extract?
Sasa Senanensis Leaf Extract comes from the leaves of Sasa senanensis, a type of bamboo grass native to Japan’s mountainous regions. The leaves are rich in polyphenols, chlorophyll, minerals and volatile aroma compounds that give the plant its fresh green scent and protective qualities. For centuries the leaves were steeped in baths and used to wrap food in Japan because of their clean scent and natural preservative power. Modern cosmetic labs pick up on these traditional uses and now include the extract in skin and hair formulas.
To make the extract, harvested leaves are washed, dried then soaked in a mix of water or a gentle solvent such as glycerin. The liquid is filtered and concentrated, yielding a clear or pale green fluid packed with antioxidants and deodorizing molecules. This ingredient ends up in face masks, purifying cleansers, after-shave lotions, antiperspirant sticks, soothing toners, lightweight moisturizers and even minty-fresh toothpastes.
