Science
Mechanism of Action
This extract acts on the skin through diverse biological pathways. It bolsters the skin's defense against oxidative stress by up-regulating antioxidant enzymes such as superoxide dismutase (SOD)-1, SOD-2, and catalase. Its anti-inflammatory efficacy stems from reducing pro-inflammatory cytokines like IL-6 and TNF-α, and modulating key signaling pathways including NF-κB/AP-1. Furthermore, Scrophularia Buergeriana Extract contributes to skin brightening by directly inhibiting tyrosinase, the enzyme central to melanin synthesis. It also demonstrates anti-allergic properties by decreasing histamine release and suppressing specific inflammatory cytokines in mast cells, thereby reducing hypersensitivity reactions.

Key findings
- 01 Inhibited tyrosinase formation, leading to skin whitening effects in a composition containing a hot water extract.
- 02 Markedly inhibited β-hexosaminidase and histamine release, suppressed TNF-α and IL-4 cytokines by mast cells, and reduced allergic inflammation in a dinitrofluorobenzene-induced contact hypersensitivity mouse model.
- 03 Promoted MCF-7 cell proliferation by regulating the cell cycle and increasing ERα expression, AKT and ERK phosphorylation, suggesting estrogen-like activity.

Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet reviewed this ingredient. However, a specific skin whitening composition containing its hot water extract was reportedly well-tolerated with no skin irritation and demonstrated high safety. Comprehensive general safety information regarding GHS classification, hazard/precautionary statements, and toxicity (oral, dermal, inhalation) is currently undetermined or not readily available in all databases.
