DESCHAMPSIA ANTARCTICA LEAF EXTRACT.

This extract, often marketed as Edafence®, operates through multiple pathways to protect and rejuvenate skin. It fortifies skin barrier integrity, promotes the self-renewal of epidermal stem cells, and enhances overall cellular repair. Acting as a potent antioxidant, rich in phenolic compounds like apigenin and luteolin, it neutralizes oxidative stress and primes endogenous antioxidant defenses. The extract effectively mitigates DNA damage from UV radiation, blue light, and various xenotoxins such as hydrogen peroxide, dioxins, and tobacco smoke. It also modulates cellular responses to stress, blunting the Aryl Hydrocarbon Receptor (AhR) and restoring loricrin expression, crucial for skin homeostasis. Furthermore, it inhibits matrix metalloproteinases (MMPs) linked to extrinsic aging, reduces stress-induced autophagy, and decreases cellular death caused by UV and blue light, simultaneously diminishing melanogenic signaling pathways and blue light-induced hyperpigmentation.
