Science
Mechanism of Action
This extract delivers significant hydration and acts as a potent antioxidant, primarily due to its rich content of polyphenols which help defend the skin from environmental damage and maintain a youthful appearance. It offers soothing and anti-inflammatory benefits to calm sensitive or irritated skin, reducing redness and discomfort, while simultaneously reinforcing the skin's barrier against pollutants and moisture loss. Naturally rich in silica, a trace mineral, it aids in collagen production for improved skin elasticity and firmness. The extract also provides a gentle astringent effect that can refine skin texture and minimize pore size, alongside its proven ability to inhibit melanin synthesis for a brighter, more even skin tone.

The Formula
Formulation
Stability
A 10% emulsion of moso bamboo leaf extract in water has shown stability. An optimal pH of approximately 7.0 has been identified for the activity of enzymes immobilized on Phyllostachys pubescens lignin, suggesting a neutral pH range may be beneficial for the stability of certain bamboo-derived compounds.
Safety
Safety Profile
Generally regarded as safe and well-tolerated by most users as a natural ingredient, its safety is recognized by regulatory bodies such as the European Cosmetics Regulation. However, the Cosmetic Ingredient Review (CIR) has not yet provided a comprehensive assessment, indicating a lack of sufficient public data for a definitive 'safe as used' conclusion. A patch test is recommended for individuals with known allergies or skin sensitivities, as rare instances of redness, itching, or irritation may occur.
