Science
Mechanism of Action
This extract primarily functions as a natural surfactant due to its high saponin content, effectively emulsifying oils and impurities for gentle yet thorough cleansing. It establishes a protective film on the skin, enhancing smoothness, softness, and preventing moisture loss, thus acting as a conditioning and hydrating agent. Furthermore, it supports a balanced skin microbiome, aids in mild exfoliation for cell renewal, and provides antioxidant protection against free radical damage through its saponins, polyphenols, and flavonoids. Its anti-inflammatory effects can soothe irritation, rebalance pH, regulate sebum, and it can notably boost the efficacy and penetration of other active ingredients in a formulation.
