PATRINIA SCABIOSIFOLIA ROOT EXTRACT.

This extract exerts its beneficial effects on the skin through several precise pathways. It significantly promotes human dermal keratinocyte proliferation and migration, alongside increasing type I and IV collagen production, indicating robust support for skin regeneration and wound healing. These actions are mediated via the Akt/Erk1/2 pathway, which also upregulates barrier proteins and increases filaggrin expression, thereby strengthening the skin barrier and potentially attenuating atopic dermatitis-like lesions. Furthermore, it demonstrates potent anti-inflammatory activity, notably by inhibiting the NF-κB pathway (73.44% inhibition at 10 μM for an isolated compound) and modulating the IL-17/CCL2 pathway to diminish UVB-induced inflammation, erythema, and epidermal thickening. It also acts as a powerful antioxidant, protecting against oxidative damage, and exhibits antibacterial efficacy against Methicillin-Resistant Staphylococcus epidermidis (MRSE) at 5 mg/mL. Additional benefits include reduced sebum production through lipoxygenase inhibition, anti-aging effects by inhibiting MMP-1, and potential brightening through tyrosinase inhibition, all while creating a long-lasting moisture reservoir for up to 72 hours.
