Pseudozyma Epicola … Filtrate

This is a composite ingredient that combines several plant-derived components: oils from argan, olive, and sunflower seed, alongside a fermented extract made from three traditional botanical roots (Angelica gigas, licorice, and Lithospermum erythrorhizon). The fermentation process breaks down plant material into smaller, potentially more bioavailable compounds. Pseudozyma epicola is a yeast used in the fermentation.In skincare formulations, this ingredient functions as an emollient and skin conditioner, meaning it helps soften the skin surface and improve the feel and appearance of the skin…

The fermented root extracts are produced by allowing Pseudozyma epicola to metabolise the plant material, which can enhance the extraction of bioactive compounds and potentially improve their stability in formulations. This fermentation may increase the concentration of phenolic compounds and other secondary metabolites from the roots.Once applied to skin, the blend of oils provides emollient properties that coat the skin surface and help reduce moisture loss, whilst the fermented extracts may deliver botanically-derived antioxidants and conditioning agents that support overall skin health.

This ingredient is typically used as part of a broader formulation rather than in isolation. It works well in moisturisers, serums, and conditioning masks. Since it contains oils, it may be layered after lighter serums and before occlusive creams if desired, though formulation design often determines optimal application order. Use as directed by the product instructions.

Generally well-tolerated, though individuals with known sensitivity to any of the botanical components (argan oil, olive oil, sunflower oil, licorice, or Lithospermum) should patch-test first. No significant safety concerns are documented for typical cosmetic use.
