Science
Mechanism of Action
This ingredient functions as a multifaceted skin conditioning agent, leveraging the transformative power of fermentation. The Saccharomyces yeast facilitates the breakdown of intricate molecules derived from the botanical and animal components, yielding smaller, more easily absorbed compounds and beneficial postbiotic byproducts. These yeast ferment filtrates are known to intensely moisturize the skin, refine texture, promote brightness, and contribute to overall toning. Additionally, they offer anti-aging benefits by boosting skin barrier function, supporting cellular renewal, and potentially aiding in the treatment of hypopigmentation. The probiotic aspects of the ferment work to balance the skin's microbiome, mitigate cellular damage, and provide both anti-inflammatory and antibacterial effects.

Key findings
- 01 Saccharomyces Ferment Filtrate is effectively utilized in leave-on products at concentrations ranging from 0.1% to 5%, and in rinse-off formulations up to 10%.
- 02 Galactomyces Ferment Filtrate, a related yeast ferment, has demonstrated benefits across 1-12% concentrations, including enhanced moisturization, improved skin radiance, maintenance of a healthy microbiome, anti-aging properties, and boosted skin barrier function, along with benefits for hypopigmentation.
- 03 Higher concentrations of Galactomyces, specifically between 10-100%, have been shown to reduce the appearance of discolorations, provide potent antioxidant activity, and help soothe skin prone to sensitivity and redness. It is noted that very high doses within this range might impart a greasy sensation.

Stability
General ferment filtrates demonstrate pH stability within ranges such as 3.0-6.5 and 4-7. For optimal skin health and ingredient performance, skincare products are typically formulated within the skin's natural acidic pH range of 4-6 or 4.5-5.5. It is advisable to avoid exposure to temperatures exceeding 40°C for certain ferment filtrates to maintain their stability.
Conflicts
- High-pH ingredients
- Strong exfoliants
- Ingredients that may interact negatively with specific ferment byproducts
Safety
Safety Profile
While this specific complex ingredient lacks a direct CIR report, general Saccharomyces Ferment Filtrate is recognized as a safe cosmetic ingredient with no reported side effects. A tentative CIR report for Galactomyces Ferment Filtrate, a similar yeast-derived ingredient, also indicated its safety for cosmetic applications. However, certain individuals may experience breakouts from fermented ingredients, potentially due to enhanced absorption of smaller molecules, the presence of new byproducts, or pre-existing yeast allergies.
