Lactococcus Ferment Lysate

Lactococcus Ferment Lysate is a postbiotic created by fermenting Lactoccus lactis, a type of bacteria more commonly used to create Lactic acid.

Postbiotics are inactive molecules produced by probiotic bacteria that provide skin benefits.

This ingredient offers promising benefits, but it is relatively new and more evidence is needed to prove its efficacy. The manufacturer claims this ingredient:

• Increases the thickness of our outermost layer of skin
• Hastens cell renewal
• Simulates antimicrobial peptides in our skin cells.

A study from 2022 found this ingredient helped protect skin against damaged from UV exposure (though this should not replace your sunscreen!).

The lysate in the ingredient name refers to a fluid that forms from breaking down the cell membrane.
