NK‑024 Saccharomyces/Rice Ferment Filtrate – The Gentle, Brightening Postbiotic for Healthy, Glowing Skin
A 99% pure, ready‑to‑use filtrate from traditional rice fermentation with Saccharomyces yeast – rich in vitamins, minerals, and bioactive enzymes. Clinically proven to whiten, soothe, hydrate, fight free radicals, and balance sebum.
Product Overview:
For centuries, Asian cultures have used rice water and fermented rice for beautiful skin. NK‑024 modernises this ancient wisdom through controlled fermentation of rice with Saccharomyces yeast. The process releases a wealth of bioactives:
-
Vitamins B1, B2, B6 – essential for skin metabolism and radiance
-
Minerals (K, P, Mg, Ca) – support skin structure and function
-
Bioactive enzymes – gently exfoliate and improve nutrient absorption
-
Polyphenols and organic acids – provide antioxidant and pH‑balancing effects
The resulting filtrate is cell‑free, stabilised with a mild preservative system (0.5% hydroxyacetophenone + 0.5% 1,2‑hexanediol), and can be used as a main base (up to 70%) or as an active booster.
| Benefit | Mechanism | Test Data |
|---|---|---|
| ✨ Whitening & brightening | Inhibits tyrosinase activity – blocks melanin synthesis | 92.86% tyrosinase inhibition (100 mg/mL) |
| ⚡ Antioxidant | Scavenges free radicals – protects against oxidative stress | 43.70% DPPH radical scavenging (neat) |
| 🌿 Anti‑inflammatory | Downregulates IL‑8 production – calms irritation, redness | Significant IL‑8 reduction (P<0.001) |
| 💧 Deep hydration | Improves stratum corneum water content | 21‑108% relative humidity over 24h |
| 🦠 Anti‑acne | Natural antimicrobial activity | >7 mm inhibition zone against C. acnes |
| 🧴 Sebum balance & oil control | Regulates excess sebum, instant brightening | Helps maintain oil/water balance, evens tone |
| 🔄 Anti‑aging | Boosts skin elasticity, reduces fine lines | Supports natural collagen & elastin function |

Proven Efficacy (in‑vitro):
-
Tyrosinase inhibition: 92.86% at 100 mg/mL – excellent whitening potential (P<0.05).
-
DPPH radical scavenging: 43.70% (neat) – strong antioxidant activity.
-
IL‑8 downregulation: Significant reduction (P<0.001) – confirms anti‑inflammatory/soothing efficacy.
-
Hydration: Relative moisture retention between 21.1% and 107.95% over 24 hours.
-
Antibacterial: Inhibition zone >7 mm against C. acnes – effective anti‑acne.
Why NK‑024 Stands Out:
✅ Ultra‑high purity – 99% ferment filtrate, minimal preservatives, clean label.
✅ Multi‑functional – whitening, antioxidant, anti‑inflammatory, moisturising, anti‑acne, sebum balancing.
✅ Natural & skin‑friendly – derived from traditional rice fermentation, no harsh chemicals.
✅ Versatile – can be used from 1% up to 70%, even as the main water phase.
✅ Scientifically supported – data on tyrosinase, DPPH, IL‑8, hydration, and antibacterial activity.
Formulation Guidelines:
-
