HAMAMELIS VIRGINIANA（WITCH HAZEL）Ferment Filtrate – Fermented Astringent for Pore Tightening, UV Protection & Barrier Repair
A lactobacillus‑fermented Hamamelis virginiana water – enhances natural astringency and antioxidant activity. Clinically proven to reduce UV‑induced malondialdehyde (lipid peroxidation), repair laser‑damaged skin, and restore barrier function better than hyaluronic acid.
Product Overview:
HAMAMELIS VIRGINIANA（WITCH HAZEL） has been used for centuries as a natural astringent to tighten pores, reduce inflammation, and soothe irritated skin. However, conventional witch hazel extracts can contain alcohol and limited active concentrations.
Our HAMAMELIS VIRGINIANA（WITCH HAZEL） Ferment Filtrate is produced by fermenting witch hazel water with lactobacillus. Fermentation:
-
Preserves and enhances the natural tannins and polyphenols.
-
Increases bioavailability of active compounds.
-
Adds beneficial bacterial metabolites (organic acids, peptides) that support skin health.
-
Results in a gentle, alcohol‑free, high‑performance active.
| Benefit | Mechanism / Data |
|---|---|
| 🔬 Tightens enlarged pores | Tannins bind and precipitate proteins, visibly reducing pore size. 30% concentration showed visible improvement after 7 days. |
| 🛡️ UV & photoaging protection | Reduces skin malondialdehyde (MDA) – a marker of lipid peroxidation from UV exposure. Fermented version significantly outperforms non‑fermented witch hazel extract at the same concentration (10%). |
| 💧 Barrier repair & hydration | Forms a protective film on the stratum corneum, reduces TEWL, and promotes water diffusion into keratinocytes. In laser‑damaged skin, ferment filtrate restored barrier more effectively than hyaluronic acid (P<0.05). |
| 🌿 Soothing & anti‑inflammatory | Calms redness, irritation, and sensitivity – ideal for post‑procedure or reactive skin. |
| 🧴 Skin conditioning | Improves overall texture and smoothness. |

Comparative Efficacy Data:
-
UV protection (mouse model): Both 10% non‑fermented extract and 10% ferment filtrate reduced UV‑induced malondialdehyde (MDA) levels (P<0.05). The fermented version showed significantly greater reduction than the non‑fermented extract.
-
Barrier repair (laser‑damaged skin): After treatment, witch hazel ferment filtrate restored transepidermal water loss (TEWL) and stratum corneum hydration more effectively than hyaluronic acid (P<0.05).
-
Pore tightening: 30% ferment filtrate applied for 7 days visibly reduced pore size (human visual assessment).
