Science
Mechanism of Action
This ingredient operates via its high concentration of flavonoids, such as rutin and quercetin, which act as powerful antioxidants to neutralize free radicals and mitigate oxidative stress that leads to skin aging. Its anti-inflammatory properties effectively soothe irritated skin, reduce redness, and alleviate discomfort associated with inflammatory conditions. The powder also targets hyperpigmentation by inhibiting melanin production, promoting a more even skin tone. Furthermore, it is believed to stimulate collagen synthesis to enhance elasticity and accelerate wound healing, while also strengthening the skin's barrier function by regulating keratinocyte differentiation. It additionally supports healthy blood circulation for nutrient delivery and provides general skin conditioning.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) indicates 'insufficient data' for Sophora Japonica's safety evaluation, necessitating further toxicology and clinical studies. While the 'extract' form is Generally Recognized As Safe (GRAS) for certain applications, this status does not universally apply to the flower powder in all cosmetic contexts. However, the European Commission lists Sophora Japonica Flower Powder for accepted cosmetic functions including antioxidant, hair conditioning, skin conditioning, and skin protectant.
