Product Overview:
Lactobacillus ferment filtrate is obtained by cultivating Lactobacillus species, then inactivating and filtering the culture to retain all the beneficial metabolites produced during fermentation – including peptidoglycan, teichoic acid, phospholipids, sterols, fatty acids, enzymes, peptides, amino acids, nucleotides, and extracellular polysaccharides. It contains no live bacteria, only the postbiotic actives.
NK‑022 is a high‑purity (99%) liquid formulated with a mild preservative system (0.5% hydroxyacetophenone + 0.5% 1,2‑hexanediol) for stability. It can be used as a main base (up to 90%) or as an active ingredient in various formulations.
| Benefit | Mechanism | Test Data |
|---|---|---|
| ✨ Whitening & brightening | Inhibits tyrosinase activity – reduces melanin synthesis | 88.01% tyrosinase inhibition (100 mg/mL) |
| ⚡ Antioxidant | Scavenges free radicals – prevents oxidative stress | 13.05% DPPH radical scavenging (100 mg/mL) |
| 🌿 Soothing & anti‑inflammatory | Reduces NO production – calms irritation, redness | 3.08% NO reduction (P<0.05) |
| 🦠 Anti‑acne | Natural antibacterial peptides – inhibits C. acnes | >7 mm inhibition zone – effective |
| 💧 Deep hydration | Rich in lactic acid & sodium lactate (NMF components) | Boosts stratum corneum moisture, reduces TEWL |
| 🛡️ Microbiome support | Forms a protective biofilm – balances skin flora, prevents pathogen adhesion | - |
| 🔄 Barrier repair | Strengthens stratum corneum metabolism, removes dead skin, improves pigmentation | - |

Proven Efficacy (in‑vitro):
Tyrosinase inhibition: 88.01% at 100 mg/mL – superior whitening efficacy (P<0.05 vs. blank).
DPPH radical scavenging: 13.05% at 100 mg/mL – significant antioxidant/anti‑wrinkle potential (P<0.05).
NO (nitric oxide) suppression: 3.08% reduction in LPS‑induced RAW264.7 macrophages – significant soothing effect (P<0.05).
Antibacterial (against C. acnes): Inhibition zone diameter >7 mm – confirms anti‑acne activity.
Why NK‑022 Stands Out:
✅ Ultra‑high purity – 99% ferment filtrate, minimal preservatives.
✅ Multi‑functional – whitening, antioxidant, anti‑inflammatory, anti‑acne, moisturising, microbiome balancing.
✅ Natural & gentle – no live bacteria, no harsh chemicals, mimics skin’s natural NMF.
✅ Extremely versatile – can be used from 1% to 90%, even as the main water phase.
✅ Scientifically supported – data on tyrosinase, DPPH, NO, and antibacterial activity.
Formulation Guidelines:
Dosage: 1‑90% depending on desired efficacy. For sheet masks and toners, up to 90% can be used as the base.
Addition: Add at any stage (heat‑stable up to 80°C). For optimal preservation, add during cool‑down phase.
Compatibility: Compatible with most non‑ionic, anionic, and amphoteric ingredients.
Applications:
Whitening & brightening serums
Soothing & anti‑redness toners
Anti‑acne gels & spot treatments
Sheet mask bases (up to 90%)
Waterless / anhydrous formulations
Microbiome‑friendly daily moisturisers
