About this ingredient
Lactococcus Ferment Extract is a postbiotic obtained by fermenting Lactococcus bacteria. It provides metabolites such as peptides and polysaccharides used in cosmetics for a soothing action and barrier support, within the microbiome care trend. The efficacy assessment calls for balance. Postbiotics make theoretical sense and have some early data on comfort and barrier, but strong clinical evidence is still limited. It works as a reasonable supporting active, useful for calming the skin and boosting the sense of barrier, without being a treatment with guaranteed results. In topical use it has no systemic relevance, so it can be applied during pregnancy and breastfeeding. Irritation and allergy potential are low, which makes it suitable for sensitive and reactive skin. Most people tolerate it very well.
