Science
Mechanism of Action
This ferment delivers essential nutrients and antioxidants, actively neutralizing free radicals to protect skin from oxidative stress. It strengthens the skin's natural barrier, enhancing moisture retention and overall resilience. The ingredient also reduces inflammation, promotes collagen synthesis to improve elasticity, and aids in smoothing fine lines. Certain derivatives inhibit tyrosinase activity for skin brightening, while its enzymatic properties gently exfoliate by preventing dead skin cell accumulation. Functioning as a prebiotic, it nurtures beneficial skin bacteria, supports microbiome balance, and possesses enzymatic action against malodor.

Key findings
- 01 A fermented product filtrate demonstrated a 37.2% reduction in trans-epidermal water loss (TEWL) and a 62.5% increase in stratum corneum hydration over four weeks.
- 02 An extract significantly improved skin hydration, microrelief, TEWL, and texture after 30 days.
- 03 Increased skin brightness was observed after three weeks in a clinical whitening study.
- 04 Provided gentle exfoliation, leading to smoother, brighter, more hydrated skin, with reductions in dark spots and textural irregularities, demonstrating suitability for sensitive skin.

Dusting Analysis
Saccharomyces Ferment offers a wide spectrum of clinically supported benefits, including hydration, barrier reinforcement, brightening, and gentle exfoliation, with demonstrated efficacy across various concentrations. Its multi-functional profile and low irritation risk position it as a valuable active ingredient, unlikely to be used merely for 'dusting' purposes.
The Formula
Formulation
Stability
Highly soluble in water and stable up to 60°C. For optimal integration, incorporate during the cooling phase of the formulation. Optimal storage is maintained at 23-25°C, with a permissible range of 16-32°C. Freezing is to be avoided to preserve ingredient integrity.
Safety
Safety Profile
The CIR Expert Panel considers yeast-derived ingredients, including those from Saccharomyces cerevisiae, safe for cosmetic use when derived from species with established dermal sensitization and food use status. The FDA affirms Saccharomyces cerevisiae as Generally Recognized As Safe (GRAS) for food applications up to 5%. It is commonly used in leave-on products from 0.1%-5% and up to 10% in rinse-off products, with formulations safely employing up to 30%.
