Science

Mechanism of Action

This potent extract functions by stimulating the skin's intrinsic collagen and hyaluronic acid synthesis, leading to a visible reduction in the appearance of fine lines and an improvement in overall skin microrelief. Its beta-glucans serve as powerful humectants, attracting and retaining moisture for enhanced plumpness and suppleness, while also exerting antioxidant and soothing properties. Additionally, it aids in reducing hyperpigmentation for brighter skin and supports a healthy skin microbiome by promoting beneficial commensal flora.

Stability

Yeast extract is generally water-soluble, particularly its beneficial components such as amino acids, ribonucleotides, minerals, vitamins, and peptides. While the specific optimal pH for stability in cosmetic formulations is not precisely defined, yeast protein precipitation studies indicate good results around pH 3.5-4.0.

Synergies

  • Can stimulate hyaluronic acid synthesis in the skin via Glycokines when part of a complex like Optim Hyal, leading to smoother and more supple skin.
  • Contains soothing antioxidant beta-glucans, offering benefits potentially surpassing colloidal oatmeal in reducing itchy skin.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

Generally considered safe for topical application in cosmetic products, with its source, Saccharomyces cerevisiae, affirmed as Generally Recognized As Safe (GRAS) by the FDA for food use up to 5%. It is classified in Toxicity Category IV (least toxic) via oral and dermal routes. While adverse reactions are uncommon, a patch test is recommended before widespread use. It's noteworthy that some individuals, particularly those with atopic dermatitis, may exhibit positive skin prick tests to Saccharomyces cerevisiae extract (20% in one study), indicating a potential for allergic reactions in this sensitive population. Data on topical usage during pregnancy and breastfeeding are currently lacking, advising consultation with a healthcare professional.
