What Is Hydrolyzed Lactobacillus Ferment?
Hydrolyzed Lactobacillus Ferment comes from Lactobacillus, a friendly bacteria best known for its role in yogurt and other fermented foods. In the lab technicians break down the ferment using water, enzymes or mild acids, turning large proteins into smaller, more skin-ready fragments. This process is called hydrolysis and it helps the ingredient blend smoothly into cosmetic formulas.
Interest in probiotic-inspired skincare took off in the early 2000s when researchers noticed that fermented ingredients could help support a healthy skin barrier. Brands soon began adding Hydrolyzed Lactobacillus Ferment to products aimed at calming stress-prone skin and fighting early signs of aging.
You will usually spot this ingredient in lightweight serums, daily moisturizers, essence-style lotions, sheet masks and eye creams where it partners well with vitamins and plant extracts.

Comedogenic Rating
Rating: 0/5
Hydrolyzed Lactobacillus Ferment is fully water soluble and contains no heavy oils or waxes that could block pores, so it earns the lowest possible comedogenic score. Its lightweight nature allows it to sit on the skin without forming an occlusive film, which minimizes the chance of trapped sebum or debris.
This makes the ingredient suitable for people who are prone to acne or frequent breakouts. Most of the time any pimples that appear while using a product containing this ferment are linked to other rich ingredients in the same formula rather than the ferment itself.
As with any skincare component overall pore-friendliness also depends on the entire product, how heavily it is applied and personal skin tendencies.
