Science
Mechanism of Action
Lactococcus/Milk Ferment Lysate functions as a postbiotic, delivering beneficial compounds resulting from bacterial fermentation. It fortifies the skin's inherent barrier, bolstering its defenses and improving resilience. The ingredient actively promotes a healthy skin microflora, modulates immune responses, and mitigates inflammation, thereby enhancing skin vitality and encouraging cell regeneration. Furthermore, it stimulates antimicrobial peptide production, supports epidermal growth, and measurably increases stratum corneum thickness, leading to superior barrier function. It also offers protection against oxidative stress and environmental damage, including UV-induced premature aging.
