The live probiotic lactic acid bacteria (Lactobacillus plantarum LB356R & LB244R) are inactive in the product, but are activated by the moisture on your skin when applied.

LB356R binds to the C. acnes bacterium and fights blemishes without irritating, drying or impairing skin health.

LB244R fights Staphylococcus aureus, a bad skin bacterium that can also cause problems for acne-prone skin.

At the same time, LB244R control the pH of the skin at around 4.5. This allows the beneficial Lactobacillus bacteria to thrive, while it becomes too acidic for most "bad" bacteria, which therefore cannot survive.
