About
A dual ferment of Lactobacillus and marine diatom Skeletonema — yields a postbiotic rich in peptides and polysaccharides.
Lactobacillus/Skeletonema ferment is produced by co-culturing Lactobacillus (probiotic bacterium) with Skeletonema (a marine diatom). Fermentation generates lactic acid, peptides, oligosaccharides, omega-3 fatty acids (from the diatom), and polyphenolic compounds. It is positioned as a postbiotic conditioning and antioxidant ingredient, often in marine-inspired skincare. Lactobacillus ferments broadly have a decades-long safe cosmetic use history; the added Skeletonema component introduces marine-algae chemistry with possible iodine/halogen trace content. No specific CIR/SCCS opinion on this combination.
