Lactobacillus Ferment

Lactobacillus ferment is a biotechnological product – a mixture of metabolic products of Lactobacillus culture, or a mixture of broken-down cells, cellular structures, and enzymes from the same culture.

Different forms and extracts have been reported in literature and patents as beneficial skincare ingredients with various effects, here presented in the order from the most well-researched.

There is clinical evidence (in an experiment performed on volunteers and compared to a placebo) that bacteria Lactobacillus plantarum has anti-aging effects, and can improve skin hydration, elasticity, and gloss. A broken down bacterial "soup" (scientifically named “lysate”) of Lactobacillus rhamnosus had barrier repair effects on skin models in test tubes.

One patent holder claims the same – that Lactobacillus extract has protective effects on the skin related to the defense against microorganisms.

Lastly, another patent holder claims that the Lactobacillus ferment contains DNA-repairing enzymes which are allegedly able to prolong the life of skin cells. This particular claim remains unsubstantiated.
