In our reference data, Ferment Extract can feed Malassezia (fungal acne).
Ferment extracts are bioactive ingredients produced by fermenting plant, yeast, or bacterial substrates, yielding amino acids, peptides, organic acids, and polysaccharides. They are used in skincare for hydration, antioxidant, and skin-barrier-supporting effects.
| Reported effect | How often | Notes |
|---|---|---|
| Mild irritation or stinging | Uncommon | More likely on sensitive or compromised skin, sometimes from residual fermentation acids. |
| Contact allergy/sensitization | Rare | Reactions linked to specific botanical substrates or fermentation byproducts. |
| Redness or transient erythema | Uncommon | Usually self-limiting after initial use. |
| Acneiform breakouts | Rare | Possible in acne-prone individuals depending on formulation richness. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
