Lactococcus Ferment Lysate

A lysate (cell breakdown product) from a beneficial lactic acid bacterium used as a conditioning agent and potential probiotic-adjacent ingredient. Generally well tolerated, though people with milk or dairy sensitivity or specific probiotics sensitivities should patch test first.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
