Yeast Extract

Yeast extract is a silky, clear liquid derived from yeast (usually Saccharomyces cerevisiae or Torula yeast).

This ingredient has plenty of skin benefits:

• It contains beta-glucan, a great skin soothing and protecting ingredient.
• It also contains glucosylceramides, a skin barrier strengthening ingredient.
• As a probiotic, this ingredient supports a healthy microbiome and skin barrier.
• It is rich in antioxidants, B vitamins, minerals, and fatty acids.

Bioferments of yeast and soy have been found to reduce hyperpigmentation at low levels.

Fungal acne

Yeast extract is fungal acne safe because it's made up of amino acids, peptides, B vitamins, and nucleotides (not the C11-C24 fatty acids that Malassezia needs to thrive).

The "yeast" in the name can be misleading, but FA safety is about chemical composition and not ingredient origin.
