Lactobacillus Ferment

What-it-does: soothing, preservative


Lactobacillus ferment is an interesting probiotic ingredient with some promising properties. 

First, according to a 2009 Estee Lauder patent, it’s a DNA repair enzyme and it can help to protect the skin against environmental aggressors.

Second, still according to Estee Lauder research but now from 2012 the ingredient has anti-microbial and anti-inflammatory properties and holds promise in the treatment of acne and rosacea. For the former one 5% was needed to show effectiveness, but for reducing skin sensitivity already 1% showed results. 

The anti-acne effect is confirmed also by US manufacturer, Barnet, that says that Lactobacillus ferment is helpful in killing harmful bacteria and creating a healthy balanced microflora. Compared to well-known anti-acne and anti-inflammatory salicylic acid the probiotic worked faster at reducing the size and redness of acne lesions. 

It also goes by the trade name Leucidal Liquid SF and can serve in the formula as a natural preservative. 

Bottom line: It’s not the most proven ingredient (yet) but definitely a very promising one especially if you have sensitive skin, acne or rosacea.
