What Is Lactobacillus/Portulaca Oleracea Ferment Extract?
Lactobacillus/Portulaca Oleracea Ferment Extract comes from the whole purslane plant after it has been fermented by the friendly bacterium Lactobacillus. Purslane is a succulent rich in vitamins A, C and E, omega-3 fatty acids and minerals like magnesium and potassium. When the plant is fermented the process breaks down large molecules into smaller ones, making its nutrients easier for skin to absorb while creating new by-products called postbiotics that help keep formulas stable.
Fermentation of botanical ingredients has roots in traditional food preservation, and Korean skincare brands were among the first to apply the same idea to cosmetics in the early 2000s. Purslane quickly gained attention for its soothing and antioxidant qualities. Combining it with Lactobacillus offered a gentle way to concentrate those benefits without harsh solvents, so formulators began adding the extract to moisturizers, essences, sheet masks and leave-on anti-aging treatments.
To make the extract fresh purslane is cleaned, ground and mixed with a water base. A controlled dose of Lactobacillus is added and the mixture is kept at a warm temperature for several days. After fermentation the liquid is filtered to remove solids then standardized for consistency. The final product is a clear to pale amber fluid that blends well with water-based cosmetics.
You will most often see Lactobacillus/Portulaca Oleracea Ferment Extract in hydrating gels, calming serums, after-sun lotions, brightening masks, eye creams and lightweight day moisturizers aimed at sensitive or aging skin.

Comedogenic Rating

Summary

The purslane plant supplies vitamins A C and E plus omega-3s while fermentation breaks these nutrients into smaller skin-friendly fragments and creates postbiotics that calm and hydrate.
