Science
Mechanism of Action
This lipo-amino acid functions by promoting the health and vitality of skin adipocytes, critical for maintaining natural facial plumpness and volume, particularly in areas like the cheeks. It reinforces the skin's inherent support system by significantly boosting the gene expression of collagen-1 and its crucial chaperone proteins, which are vital for extracellular matrix integrity. Furthermore, it enhances the contractile forces of dermal fibroblasts and improves collagen organization, leading to improved cell adhesion and a noticeable firming effect. Palmitoyl Isoleucine also possesses potent antioxidant and detoxifying properties by stimulating the proteasome to clear damaged proteins and protect against reactive hydroxyl radicals. Its deep penetration capabilities also support skin hydration, reduce inflammation, and facilitate repair.
