Science
Mechanism of Action
This extract functions as a potent skin moisturizer and anti-aging agent. It stimulates the skin's natural production of collagen, effectively addressing both intrinsic (chronobiological) and extrinsic (photo-induced) skin aging processes. Furthermore, it enhances skin hydration and suppleness by stimulating hyaluronic acid synthesis through signaling oligosaccharides, known as Glycokines, and also contains essential vitamins, minerals, and amino acids to nourish the complexion.

Key findings
- 01 Clinical investigations have shown that Kluyveromyces extract significantly contributes to anti-aging effects by enhancing collagen synthesis, thereby mitigating both age-related and sun-induced skin aging.
- 02 As a form of hydrolyzed yeast extract, it functions as an effective skin moisturizer, stimulating endogenous hyaluronic acid production to yield smoother, more hydrated, and supple skin.
- 03 Further research indicates its potential to diminish the appearance of fine lines and wrinkles through collagen stimulation, brighten skin by reducing hyperpigmentation, and improve overall skin hydration via humectant properties, including beta-glucans.

Stability
Hydrolyzed yeast extracts are characteristically water-soluble. While a specific optimal pH range for the extract within cosmetic formulations is not explicitly defined, its source organism, Kluyveromyces marxianus, is highly robust, tolerating a broad pH spectrum from 2.5 to 9.0. Certain enzymatic activities associated with K. marxianus are optimally observed around pH 6.5-7.0, suggesting good stability within typical skincare pH ranges.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel has deemed yeast-derived ingredients, specifically including Hydrolyzed Kluyveromyces Extract from species like K. lactis or K. marxianus (which hold QPS status), safe for use in cosmetics under current practices and concentrations, provided the yeast species have dermal sensitization and food use status. The EWG Skin Deep® database further reinforces its safety profile, assigning a 'LOW' concern rating across categories such as cancer, allergies & immunotoxicity, and developmental & reproductive toxicity.
