How Lactococcus Ferment Lysate works 락토코커스발효용해물
Lactococcus ferment lysate is made by culturing the bacteria, then rupturing and filtering the culture, so the finished ingredient is a mixture of peptides, sugars, organic acids and cell fragments with nothing alive in it. On skin these behave as humectants and conditioning agents. Any claim that it interacts with your skin's resident microbial community goes considerably beyond what has been demonstrated in people. As with every ferment lysate, the composition depends on the strain, the growth medium and the processing, so two ingredients sharing an INCI name are not necessarily comparable.

🙋 People also ask
How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
Does Korean skincare work for deeper skin tones?
The skincare does — hydration, barrier support and soothing actives are not tone-specific. The friction points are mineral sunscreens that leave a cast and a colour-cosmetics shade range that has historically been narrow.
