In our reference data, Yeast Ferment Extract can feed Malassezia (fungal acne).
Yeast ferment extract (also called Galactomyces or Saccharomyces ferment filtrate) is a bioactive ingredient produced by fermentation, valued for its content of amino acids, vitamins, minerals, and antioxidants. It is used to hydrate, support the skin barrier, and may help improve skin tone and texture.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or stinging | Uncommon | Transient sensation more likely in sensitive or compromised skin. |
Allergic contact dermatitis | Rare | Sensitization to fermentation-derived proteins or other formulation components. |
Acneiform breakouts or folliculitis | Rare | Occasionally reported, possibly related to yeast components in predisposed individuals. |
Worsening in those with yeast/Malassezia-sensitive skin | Rare | May aggravate seborrheic dermatitis-prone skin in some cases. |
