Science
Mechanism of Action
This ingredient actively strengthens the skin's natural barrier by stimulating epidermal cell regeneration and enhancing the expression of crucial proteins responsible for intercellular binding, such as Occludin, Desmocollin 1, and Desmoglein 1. It also positively influences epidermal quality by stimulating enzymes like Kallikrein 5 and 7, which are involved in the healthy shedding of dead skin cells. By balancing the skin's microflora, Lactococcus Ferment Lysate reduces inflammation, minimizes sensitivity, redness, and dryness, and promotes the production of antimicrobial peptides, thereby enhancing the skin's overall resilience against external stressors.

Key findings
- 01 A 3% concentration of Lactococcus Ferment Lysate, applied twice daily for four days, resulted in a ~2 µm increase in stratum corneum thickness and reduced transepidermal water loss, indicative of enhanced barrier recovery and overall skin renewal.
- 02 Topical formulations containing 5% Lactococcus Ferment Lysate demonstrated a reduction in acne vulgaris severity, decreased sebum levels, and modulated cytokine profiles by lowering pro-inflammatory and enhancing anti-inflammatory markers.
