Peppermint Ferment – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Peppermint Ferment (Mentha Piperita Leaf Ferment Filtrate) is a highly bioavailable, water-soluble botanical concentrate produced via fermentation, which significantly reduces irritant potential and generates postbiotic compounds. This ferment is exceptionally gentle, providing cooling comfort (up to 26% improvement) and redness reduction (up to 20%) without the harshness of peppermint oil, while also enhancing clarity (up to 18%) and hydration(up to 15%). Used typically at 1−5% in serums and essences, its microbiome-supportive and soothing properties make it an excellent choice for sensitive, dull, combination, and oily skin seeking balanced tone, fresh radiance, and resilient comfort.
