Science
Mechanism of Action
Functioning as a sophisticated postbiotic, this ingredient fosters an optimal skin microbiome by creating an environment unfavorable to harmful bacteria and fungi. It actively promotes skin repair through accelerated cell renewal and increased collagen synthesis, enhancing skin elasticity and minimizing the appearance of wrinkles. Furthermore, it strengthens the skin's protective barrier, significantly reducing transepidermal water loss (TEWL) and improving overall hydration. The extract modulates immune responses to decrease redness, stimulates antimicrobial peptide production, and boosts keratinocyte proliferation and migration for enhanced wound healing. It also offers protection against UV-induced damage and photoaging while inhibiting melanin production to address hyperpigmentation and undereye dark circles. Its rich composition of enzymes, peptides, amino acids, and exopolysaccharides collectively delivers anti-aging, repair, antioxidant, and moisturizing effects.
