In our reference data, Saccharomyces/Copper Ferment can feed Malassezia (fungal acne).
Saccharomyces/Copper Ferment is a yeast-fermentation filtrate that delivers bioavailable copper to the skin, and is used in cosmetic formulations for purported antioxidant, soothing, and skin-conditioning effects. Copper is a cofactor in enzymes involved in collagen and elastin formation, though topical efficacy data are limited.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or transient stinging | Uncommon | Possible on sensitive or compromised skin, generally mild and self-limiting. |
Contact dermatitis / allergic sensitization | Rare | Can occur in individuals sensitive to fermentation-derived components or copper. |
Temporary discoloration or staining of skin | Rare | Copper-containing products may occasionally cause faint greenish tint at high concentrations. |
Acneiform or comedogenic reaction | Very rare | Depends on overall formulation rather than the ingredient alone. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
