Witch Hazel Fermentation Product Filtrate: A Pioneering Microbial Ecosystem Repair Solution for Oil Control and Soothing

Witch Hazel Fermentation Product Filtrate, known as the ‘breathing plant essence,’ is produced through symbiotic fermentation between lactobacillus and North American witch hazel leaves. This process converts natural components such as tannins and flavonoids into smaller, more easily absorbed molecular complexes, making it a revolutionary ingredient for oily and acne-prone skin care.

Core Technology and Enhanced Efficacy

4. Fermentation-Enhanced Efficacy: Patented dual-strain fermentation technology (plant lactobacillus + yeast) increases tannin conversion efficiency to 92%, while the generated short-chain fatty acids (SCFAs) regulate skin pH to a mildly acidic level, inhibiting Propionibacterium acnes (with an 89% antibacterial rate);

5. Dual Oil-Control and Firming Effects: Fermentation-derived polyphenolic compounds shrink pores (reducing diameter by 27%) while reducing sebum secretion (65% oil control rate after 4 hours), with efficacy enhanced by 50% when used in combination with salicylic acid;

6. Suitable for sensitive skin: Tested via skin patch testing (0% sensitisation rate), the fermentation process reduces the original irritation of witch hazel, enhances anti-inflammatory activity by 41%, and rapidly alleviates redness (58% reduction rate within 2 hours).

Diverse application scenarios

- Oil-control skincare products: Recommended addition rate of 5%-10% in toners and lotions; after 28 days of use, T-zone oiliness is reduced by 62%;

- Acne care products: Formulated into a gel with tea tree essential oil (total concentration of 8%), accelerating acne clearance by 40%;

- Scalp care series: Add to shampoo (3% concentration) to effectively inhibit dandruff and improve seborrheic dermatitis;

- Men's-specific formula: Use in aftershave to soothe post-shaving discomfort, with a 71% reduction in skin burning sensation scores.
