Science
Mechanism of Action
This ingredient functions by delivering a complex array of cosmetically active compounds, including potent antioxidants and anti-inflammatory agents, which collectively foster stratum corneum healing and barrier function restoration. It helps to significantly increase skin moisturization and improve both the integrity and strength of the skin barrier. Rich in B vitamins, vitamins A and E, and essential fatty acids like oleic and linoleic acids, it nourishes the skin. Furthermore, Macrocystis pyrifera contains alginates for viscosity control, silicon for potential anti-wrinkling effects, and phlorotannins contributing to its antioxidant defense.
