Saccharomyces/Coix Lacryma-Jobi Ma-Yuen Seed Ferment Filtrate

Saccharomyces/Coix Lacryma-Jobi Ma-Yuen Seed Ferment Filtrate is a fermented ingredient derived from Job's tears (Coix lacryma-jobi), a grain native to Asia. The seeds are fermented using Saccharomyces yeast, then filtered to create a liquid extract rich in amino acids, polysaccharides, and fermentation byproducts.In skincare, this ingredient functions primarily as a skin conditioner—it helps to soften, smooth, and maintain the skin's moisture balance. Fermented botanical extracts are thought to have enhanced bioavailability compared to unfermented forms, potentially allowing their benefici…

Fermentation breaks down the cell walls of the Job's tears seed, making its beneficial compounds more accessible to the skin. The process generates amino acids, small peptides, and other metabolites that can hydrate and condition the stratum corneum (the skin's outer layer).The polysaccharides in this extract are believed to form a light hydrating film on the skin and may support the skin's natural moisture-retention mechanisms. This makes it particularly useful in formulations designed to improve hydration without heaviness.

This ingredient is typically found in serums, essences, and hydrating toners at low concentrations. It works well in layered skincare routines and can be combined with other hydrating or conditioning ingredients. There is no specific upper limit on frequency—products containing this ingredient can usually be used daily as part of your regular routine.

Generally well-tolerated across skin types. No significant cautions documented, though those with sensitivity to fermented ingredients or specific grain sensitivities should patch-test first.
