Science
Mechanism of Action
This extract functions by boosting cellular ATP production, which enhances skin regeneration, oxygen uptake, and microcirculation, contributing to a more radiant appearance. It acts as a natural humectant, drawing and retaining moisture within the skin, while its beta-glucans and peptides offer soothing properties that reduce irritation. The ingredient also aids in skin detoxification by binding heavy metals and neutralizing environmental toxins, and supports a balanced skin microbiome. Furthermore, it reinforces the skin barrier by promoting the production of essential proteins and lipids, offering robust protection against environmental stressors. Rich in natural antioxidants, including B vitamins and enzymes, it actively combats free radical damage and inhibits key enzymes involved in melanin production, which contributes to an even skin tone and improved elasticity.

Key findings
- 01 In anti-aging and brightening serums, it boosts skin regeneration, improves tone, and adds radiance by energizing skin cells and reducing signs of fatigue.
- 02 In creams and lotions, it significantly enhances hydration, skin elasticity, and barrier repair, supporting long-lasting moisture retention and soothing environmentally stressed skin.
- 03 When incorporated into eye creams, it targets fine lines, puffiness, and dullness around the delicate eye area, leveraging its revitalizing and antioxidant properties.
- 04 Formulations containing the extract enhanced forearm skin moisture, improved skin microrelief (small wrinkles), and exhibited higher skin brightness values.
- 05 Demonstrated significant antibacterial activity against *Staphylococcus aureus* in in-vitro studies.
- 06 Showed inhibitory effect against *Cutibacterium acnes* in in-vitro studies.

Dusting Analysis
Saccharomyces Cerevisiae Extract demonstrates significant clinical efficacy across a range of topical applications, even at lower concentrations (0.5-5%). Its diverse mechanisms, including cellular energizing, hydration, barrier repair, antioxidant, and anti-inflammatory effects, are well-supported by studies at these specific percentages. This comprehensive action at relatively modest inclusion rates indicates it is a genuinely active ingredient and not typically subject to 'dusting'.
The Formula
Formulation
Stability
This ingredient is highly soluble in water and insoluble in oil, making it well-suited for aqueous cosmetic formulations. A component of *S. cerevisiae*, invertase, demonstrated stability within a pH range of 4.0 to 7.0, aligning well with typical skincare product pH values.

Safety
Safety Profile
The CIR Expert Panel currently classifies yeast-derived ingredients, including Saccharomyces Cerevisiae Extract, as having 'Insufficient Data Available' (IDA), particularly requiring more sensitization data at maximum use concentrations. However, industry practice and a long history of cosmetic use (up to 5% in rinse-off and leave-on products) indicate it is generally considered very safe, mild, non-irritating, and non-comedogenic, with no reported allergic reactions. The FDA has affirmed *Saccharomyces cerevisiae* as Generally Recognized As Safe (GRAS) for food applications up to 5%.
