Science
Mechanism of Action
Kefiran functions through anti-microbial, anti-inflammatory, and antioxidant pathways, actively supporting skin health. It aids in wound healing by promoting cell adhesion and proliferation, while simultaneously boosting skin hydration by increasing moisture levels and reducing transepidermal water loss (TEWL). Furthermore, Kefiran fortifies the skin barrier against environmental stressors, improves skin elasticity and firmness, and is indicated to enhance collagen synthesis to reduce the appearance of sagging.
