Science
Mechanism of Action
This extract primarily functions through its robust antioxidant activity, notably via Polygonatum sibiricum Fructan (PSF) which acts as a hydrogen donor to neutralize oxygen-activated free radicals. This mechanism protects the skin from oxidative damage, improves elasticity, and helps reduce the appearance of fine lines and wrinkles. Additionally, it exhibits anti-inflammatory, anti-bacterial, moisturizing, and skin-brightening effects.
