Lactobacillus/Soymilk Ferment Filtrate

Also known as: Soy yogurt, Soymilk kefir

Organic soya kefir yoghurt is a plant-based fermented ingredient made by culturing soy milk with kefir microflora. It is rich in hydrolyzed soy proteins, peptides, and amino acids that moisturize, smooth, and condition the skin and hair cuticle. It is generally very gentle, though people with diagnosed soy allergies should exercise caution.
