Brassica oleracea italica Seed Extract

Brassica oleracea italica Seed Extract is derived from broccoli seeds and is standardized to contain glucoraphanin, a glucosinolate precursor that converts enzymatically to sulforaphane — a potent Nrf2 pathway activator that upregulates the skin's own endogenous antioxidant defenses. Unlike direct antioxidants that are consumed in neutralizing free radicals, glucoraphanin's mechanism triggers a sustained, amplified cellular protective response, making it particularly valued for anti-pollution and photoprotection formulations. Formulators choose this ingredient for its clinically supported ability to bolster skin resilience against oxidative stress, UV-induced damage, and environmental aggressors at low use concentrations, typically 0.5–2%.
