What is Lactococcus Ferment Lysate?

Lactococcus Ferment Lysate (LFL) is one of the relatively new probiotic ingredients that have gained the interest of cosmetics manufacturers over recent years.

Lactococcus Ferment Lysate is a probiotic ingredient derived from the fermentation process of the bacterium Lactococcus lactis. This bacterium has a rich history in the food industry, particularly in the production of dairy products like cheese and yoghurt. In traditional medicine, products containing Lactococcus lactis have been used to promote gut health due to their probiotic properties.

Bacterial lysate is made by breaking down the bacterial culture in a water-based medium until the cells fall apart. The resulting mixture is a soup of cell fragments, various cell structures, soluble proteins, enzymes, and liquids.

In recent years, the skincare industry has turned its attention to this potent ingredient, harnessing its beneficial properties to improve skin health. The use of Lactococcus Ferment Lysate in skincare products is a testament to the growing trend of incorporating ingredients inspired by food and health sciences into beauty routines.

Lactococcus Ferment Lysate in Skincare

Skincare formulations continue to evolve, and in recent years, the focus has shifted towards the skin microbiome, the community of beneficial bacteria that reside on our skin. The desire for products that boost the skin's natural defenses has put probiotics and their byproducts, such as Lactococcus Ferment Lysate, in the limelight.

Lactococcus Ferment Lysate functions in skincare primarily through two mechanisms – barrier repair and soothing effects. It boosts the skin's ability to repair its protective barrier, which, when compromised, can lead to dryness, irritation, and heightened sensitivity.

In tandem with its soothing effects, Lactococcus Ferment Lysate helps calm inflammation and reduce redness, rendering it ideal for sensitive or inflamed skin.

Lactococcus Ferment Lysate Benefits For Skin

The transformation of Lactococcus Ferment Lysate from dairy farms to our cosmetic jars signifies its vital role in skin health. It performs several key functions:

  1. Barrier Repair: The skin barrier is the outermost layer of the skin that protects against environmental aggressors and prevents moisture loss. Lactococcus Ferment Lysate helps strengthen this barrier, making the skin more resilient and less prone to dryness and irritation. 

    One study tested a skincare formula containing a lysate of Lactococcus lactis in test-tubes on healthy volunteers and found that it improved skin barrier function, reduced water loss, and optimized skin hydration and surface pH. No skin irritation was not detected.

  2. Soothing: The calming properties of Lactococcus Ferment Lysate can help to reduce skin irritation and inflammation.

According to various patents, the lysates of probiotic bacteria have moisturizing effects and other helpful properties, although there is not enough evidence from scientific studies that can fully support these cl

Is Lactococcus Ferment Lysate Safe for Skin?

Lactococcus Ferment Lysate is generally considered safe for use in skincare products. It's derived from a bacterium that's commonly used in the food industry, and it's known for its beneficial effects on skin health. LFL is a gentle, non-irritating ingredient, making it suitable for all skin types, including sensitive skin.
