In our reference data, Lactobacillus can feed Malassezia (fungal acne).
Lactobacillus refers to a genus of lactic acid bacteria used in skincare as live cultures, ferment filtrates, or lysates to support the skin microbiome, barrier function, and provide soothing or antimicrobial effects. It is often included for its purported balancing and conditioning properties.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient irritation or stinging | Uncommon | Possible upon application, particularly on sensitive or compromised skin. |
Contact dermatitis or allergic sensitization | Rare | Reactions may relate to the ferment matrix or accompanying formulation components. |
Folliculitis or acneiform breakouts | Rare | Occasionally reported, may depend on overall formulation rather than the organism itself. |
Infection in immunocompromised individuals | Very rare | Theoretical concern with live cultures; topical use is generally considered low risk. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
