KLUYVEROMYCES/LACTOBACILLUS/SAPINDUS MUKOROSSI FRUIT OIL FERMENT FILTRATE.

Valuable / ANTIMICROBIAL, ANTIOXIDANT, BLEACHING, HAIR CONDITIONING, SKIN CONDITIONING

This advanced ferment filtrate, derived from the co-fermentation of Kluyveromyces yeast, Lactobacillus bacteria, and Sapindus Mukorossi fruit oil, offers a multi-functional approach to skin health. Through microbial metabolism, it transforms raw materials into more bioavailable and potent active compounds, delivering comprehensive benefits from combating acne to enhancing skin resilience.

Summary

Antioxidant Skin-conditioning Skin protecting Antimicrobial/antibacterial Anti-inflammatory DNA repair Mild cleansing Skin brightening

Science

Mechanism of Action

The fermentation process breaks down larger molecules into smaller, highly active forms, significantly boosting the bioavailability and efficacy of the constituent compounds. This ingredient enriches the skin with increased concentrations of beneficial saponins from Sapindus Mukorossi, along with newly formed vitamins, antioxidants, and amino acids. The Lactobacillus component acts as a DNA repair enzyme, safeguarding against environmental stressors, while its antimicrobial and anti-inflammatory properties contribute to balancing the skin's microflora, crucial for managing conditions like acne and rosacea. Furthermore, it supports cellular functions by promoting oxygen uptake, collagen production, and ATP synthesis, acting holistically as an antioxidant, skin conditioner, and protector. The natural surfactants (saponins) from the soapberry also provide mild cleansing, tyrosinase inhibition for brightening, and robust free radical scavenging capabilities.

Optimal concentrations for component efficacy range from 1% to 5% for specific benefits, though the maximum reported use for a key component in FDA VCRP data is 1.5%.

Key findings

  1. 01 Studies on related Lactobacillus Ferment demonstrate effective acne treatment, showing a faster reduction in lesion size and redness compared to salicylic acid at a 5% concentration.
  2. 02 Application of a related Lactobacillus Ferment at 1% concentration was observed to reduce skin sensitivity.
  3. 03 An in-vivo study with 5 participants indicated a 47% reduction in skin redness with 5% Lactobacillus Ferment Lysate Filtrate.
  4. 04 Fermentation filtrate from soapberry pericarp, a component of this ingredient, influenced scalp microbial diversity over 28 days, fostering healthy bacterial pathways and diminishing fungal pathogenesis. It also exhibited enhanced DPPH radical scavenging activity and increased saponin content compared to unfermented extracts.
