Cucumber Ferment – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Cucumber Ferment (Lactobacillus/Cucumis Sativus Fruit Ferment Filtrate) is a water-soluble botanical derivative created via fermentation, which boosts the bioavailability of its polyphenols, peptides, and botanical sugars, enhancing its soothing and hydrating properties. This ferment provides significant hydration improvement (observed trends up to +28%), helps with redness reduction (up to 20%), and enhances barrier comfort (up to +25%). Used typically at 1−5% in essences and serums, its microbiome-friendly profile, lightweight feel, and cooling comfort make it ideal for sensitive, irritated, dehydrated, and redness-prone skin seeking balanced, resilient, and refreshed clarity.
