Kefiran is a vegan, skin-nourishing active ingredient obtained through the fermentation of the bacterial strain Lactobacillus kefiranofaciens in a plant-based culture medium and is present as a component of a ferment lysate. (1)

In skincare, kefiran is considered a versatile active ingredient: it helps the skin defend against free radicals, counteracts oxidative stress, and can reduce redness. It also helps strengthen the skin barrier and promotes skin elasticity and firmness. This makes kefiran particularly suitable for skincare products designed to protect, regenerate, and soothe the skin. (1,2)
