Science
Mechanism of Action
Plantago Major Seed Extract is rich in bioactive compounds such as phenolics, tannins, flavonoids, iridoid glycosides, and terpenoids. Tannins interact with skin surface macromolecules, creating a protective barrier, exhibiting an astringent effect, and visibly minimizing pore size. Its comprehensive action spectrum includes anti-inflammatory, antimicrobial, antioxidant, and wound-healing capabilities. The presence of allantoin promotes healthy tissue regeneration, while the extract collectively contributes to strengthening skin elasticity and firmness, fostering healthy aging.
