KLUYVEROMYCES/LACTOBACILLUS/LACTOCOCCUS/LEUCONOSTOC/SACCHAROMYCES MILK FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

This complex ingredient, often recognized as Kefir Extract, is a sophisticated blend of bacteria and yeasts derived from fermented milk. It functions primarily as a skin conditioning agent, meticulously formulated to maintain skin health and enhance its overall appearance. Its multifaceted actions contribute to a more resilient, hydrated, and soothed complexion.

Science

Mechanism of Action

Our research indicates that this ferment filtrate operates through several key pathways to support skin health. It acts as a potent antioxidant, exhibiting DPPH radical scavenging activity to neutralize harmful free radicals. Furthermore, it demonstrates anti-irritant properties by inhibiting cytokine production, thereby calming inflamed skin. Beyond these, it actively moisturizes the skin and helps restore the protective barrier. The fermentation process also breaks down lactose, and the resulting filtrate is rich in beneficial proteins, lipids, sugars, vitamins, minerals, and amino acids, which collectively stimulate skin regeneration, promote elasticity, and contribute to a more radiant skin tone. It also shows tyrosinase inhibition activity, contributing to an even skin tone.

Key findings

  1. 01 While specific clinical studies for KLUYVEROMYCES/LACTOBACILLUS/LACTOCOCCUS/LEUCONOSTOC/SACCHAROMYCES MILK FERMENT FILTRATE were not identified, related ferment filtrates provide insight into potential benefits.
  2. 02 A 5% concentration of Saccharomyces boulardii fermented product filtrate demonstrated a significant 37.2% reduction in trans-epidermal water loss (TEWL) and a 62.5% increase in stratum corneum hydration over a four-week period.
  3. 03 Another study involving a 30% concentration of Saccharomyces Ferment (containing 3% fermented N-acetylglucosamine) showcased gentle exfoliation, improved texture, enhanced radiance, sustained hydration, and a strengthened skin barrier.
  4. 04 Fermentation residue from Saccharomyces cerevisiae has also been clinically shown to increase skin whitening activity.

Dusting Analysis

Not commonly dusted

This ingredient is a ferment filtrate, typically incorporated as a liquid component into formulations rather than as a powder in trace amounts for marketing claims. Its functional benefits are observed at higher inclusion rates (as suggested by studies on related ferments).

Sensitization risk Low

The CIR Expert Panel generally considers Lactobacillus Ferment and related filtrates safe for cosmetic use. Lactobacillus Ferment has been reported safe for use up to 5.6% in leave-on face and neck products. While Saccharomyces Ferment Filtrate is also typically safe, rare instances of allergic reactions or irritation have been noted. It is important for cosmetic formulators to be aware that while this ingredient demonstrates tyrosinase inhibition, any claim or effect of significant skin depigmentation is classified as a drug effect and falls outside cosmetic regulation.
