In our reference data, Ferment Extracts can feed Malassezia (fungal acne).
Ferment extracts are ingredients produced by microbial fermentation of plant, yeast, or other substrates, yielding bioactive compounds such as amino acids, peptides, organic acids, and antioxidants. They are used in skincare for hydration, barrier support, and antioxidant effects.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation (redness, stinging) | Uncommon | More likely with sensitive skin or higher concentrations. |
| Allergic contact dermatitis | Rare | Sensitization may occur to specific fermentation byproducts or residual substrate proteins. |
| Acneiform breakouts | Rare | Occasionally reported, possibly related to formulation rather than the ferment itself. |
| Systemic or severe reactions | Very rare | Topical use is generally well tolerated; serious effects are uncommon in literature. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
