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.
