Lactococcus Ferment Lysate For Skin

Lactococcus ferment lysate is a probiotic strain that comes from the fermentation of Lactococcus lactis and is commonly used as a probiotic to improve digestive health and boost the immune system.

It is typically found in fermented foods but in recent years has often been used as in ingredient in topical skin products. In this blog post, I am going to be sharing some studies on this probiotic strain.

What Is The Skin Microbiome?

The skin microbiome is the collective genome of the microorganisms that live on the human skin. The skin microbiome is made up of two main groups of microbes: the resident microbiome, which is the core and fixed group of microorganisms that can replenish itself after any perturbations, and the transient microbiome, which is a group of microorganisms that do not permanently reside on the skin but appear for a few hours or days depending on the environment. In healthy skin, both types of microbiomes are non-pathogenic. 

The common phyla of microorganisms found on the skin include Actinobacteria, Firmicutes, Proteobacteria, and Bacteroides. The three most common genera are Corynebacteria, Propionibacteria, and Staphylococci. The skin microbiome performs several important functions, including providing the first line of defense against invading pathogens and aiding in the regulation of the immune system.

Is Lactococcus Ferment Lysate Topically Effective For Skin Scare?

A lot of skincare brands swear by the benefits of this probiotic strain but the truth is that there is currently no research available on the effectiveness of Lactococcus Ferment Lysate when used topically for skin care.

Further research in humans is needed to determine the potential benefits of Lactococcus Ferment Lysate for skin health and you shouldn't trust any sources that make health claims without directly referencing their claim with scientific data.

This Paulaschoice blog post stated that there was a 2022 study showing skin benefits for this strain but didn't directly link to its source and it sounds like they may have gotten confused with Bifida ferment lysate which isn't the same strain.

Closing Thoughts: Oral Or Topical?

In my opinion, oral use of probiotics is considered more effective than topical use because the beneficial bacteria in probiotics are able to reach the gut and then work via the gut & skin axis. 

In the gut, probiotics can help to balance the microbiome, which is important for maintaining good skin health versus Topical application of probiotics, which only briefly exposes the bacteria to the skin.
