Science
Mechanism of Action
Extracts within the Rumex genus, such as Rumex occidentalis, primarily function by inhibiting tyrosinase, a key enzyme involved in melanin synthesis within human skin. This targeted action helps reduce the formation of unwanted pigmentation, including sun spots and age spots, contributing to a more even skin tone. Furthermore, these extracts, exemplified by Rumex occidentalis, provide antioxidant benefits through compounds like quercetin and resveratrol, offering protection against environmental aggressors and contributing to skin soothing.
