Science
Mechanism of Action
The *Rheum Palmatum* Root Extract component delivers potent anti-inflammatory effects, effectively calming irritation and reducing redness, making it particularly beneficial for sensitive skin or conditions like rosacea. It stimulates skin regeneration and cell renewal, contributing to improved elasticity and a reduction in the appearance of fine lines. This extract also offers robust antioxidant protection against free radical damage and imparts a subtle moisturizing effect, enhancing skin's natural luminosity and softness, alongside a gentle skin tone-evening action. Concurrently, the *Enterococcus faecium* ferment filtrate provides advantageous metabolites. Specifically, *Enterococcus faecium* L-15 extract has been shown to boost the self-renewal and proliferation of skin precursor cells by activating the PI3K/Akt signaling pathway, leading to enhanced skin structure and collagen formation.
