Science & Benefits

Obtained from the enzymatic hydrolysis of yeast, this protein is exceptionally rich in B vitamins and amino acids. It functions as a metabolic humectant that helps regulate sebum quality and quantity. It is zero-comedogenic. Its logical value in an acne database lies in its 'balancing' effect; it provides the hydration needed to prevent surface dryness while the fungal metabolites help stabilize the skin's microbiome, making it less hospitable to C. acnes overgrowth.
