Lactococcus Ferment Lysate

Postbiotic skin care ingredient, derived from probiotics through the fermentation process

Offers potential anti-aging benefits due to its mitigation of visible sun damage

May also improve skin’s ability to withstand compromising influences and external stressors

Works best in liquid emulsion formulations but can also be used gel/serum consistencies

Lactococcus ferment lysate is a postbiotic skin care ingredient, derived from probiotics through the fermentation process. According to a 2022 study, benefits of topical use of this ingredient include protecting skin’s surface from visible signs of environmental damage. In this capacity, Lactococcus ferment lysate also helps skin resist visible signs of aging caused by sun damage. It does not replace the need for sunscreen but can be viewed as one more line of environmental defense for skin.

Postbiotics, in general, are noted for improving the skin barrier’s ability to withstand compromising influences and external stressors.

Cosmetic suppliers of Lactococcus ferment lysate also make claims about this ingredient’s impact on cellular renewal and skin thickness. However, we did not find independent research backing these claims at the time of this review.

More studies are needed in general to validate the exact benefits of Lactococcus ferment lysate, but so far it looks promising.

According to the manufacturer’s note, Lactococcus ferment lysate works best in liquid emulsion formulations but can also be used in products with gel/serum consistencies. The recommended usage level is 3%.
