In our reference data, Olea Europaea (Olive) Oil can feed Malassezia (fungal acne).
Olive oil is a plant-derived lipid rich in oleic acid used as an emollient and occlusive to soften skin and reduce transepidermal water loss. It is commonly used as a carrier or base ingredient in creams, balms, and massage oils.
| Reported effect | How often | Notes |
|---|---|---|
Skin barrier disruption | Common | High oleic acid content can impair the stratum corneum barrier and increase transepidermal water loss, particularly in compromised or infant skin. |
Irritation or worsening of dermatitis | Uncommon | May aggravate atopic dermatitis or cause irritation, especially in eczema-prone skin. |
Comedogenicity / acne flares | Uncommon | Can clog pores and contribute to breakouts in acne-prone or oily skin types. |
Allergic contact dermatitis | Rare | Sensitization to olive oil components has been documented but is infrequent. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
