Science
Mechanism of Action
Coix Lacryma-Jobi Ma-Yuen Shell Extract functions by combating oxidative stress through its rich antioxidant profile, thereby shielding skin from environmental aggressors. It actively reduces inflammation by inhibiting nitric oxide (NO) production and modulating immune responses, including suppressing tryptase expression, histamine release, mast cell degranulation, and IL-31 cytokine production. The extract enhances skin hydration by supporting barrier function, promoting natural regeneration, and increasing the thickness of the epidermis and stratum corneum. Furthermore, it contributes to skin brightening by inhibiting tyrosinase, which lessens melanin production, and helps regulate sebum for a balanced complexion.
