Rose Ferment Filtrate – Fermented Rose for Deep Hydration & Instant Redness Relief
A lactobacillus‑fermented extract of Rosa rugosa flowers – enhances skin moisture, reduces transepidermal water loss, and calms histamine‑induced irritation. Clinically tested for soothing and hydrating efficacy.
Product Overview:
Rose Ferment Filtrate is produced by fermenting Rosa rugosa flower extract with lactobacillus. This gentle, biomimetic process breaks down plant compounds into smaller, more bioavailable molecules, enriching the final filtrate with organic acids, polyphenols, and peptides. The result is a multi‑functional active that delivers:
-
Deep, lasting hydration – increases stratum corneum water content (MMV) and reduces water loss (TEWL).
-
Immediate soothing – reduces redness and allergic reactions (histamine challenge test).
-
Enhanced skin absorption – fermented actives penetrate more easily than conventional extracts.
| Benefit | Mechanism / Data |
|---|---|
| 💧 Deep hydration | Increases MMV (moisture value) from 26.85 to 36.28 after 4 hours (25% concentration). |
| 🛡️ Locks in moisture | Reduces TEWL from 12.9 to 10.4 after 4 hours – stronger barrier. |
| 🌹 Instant soothing | 30% ferment filtrate significantly reduced histamine‑induced redness and irritation within 15 minutes (human test, n=8, age 20‑45). |
| 🌿 Good transdermal absorption | Fermentation enhances penetration – active molecules reach deeper skin layers. |
| 🧴 Versatile | Works in toners, serums, masks, creams, and mists. |
