Origanum Vulgare (oregano) Leaf Extract is a botanical derived from the oregano plant, used in skincare for its antioxidant, antimicrobial, and astringent properties, largely attributed to phenolic compounds such as carvacrol and thymol. It is included in formulations as a natural preservative booster and skin-conditioning agent.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Uncommon | Carvacrol and thymol content can cause stinging, redness, or burning, especially on sensitive or compromised skin. |
Allergic contact dermatitis | Uncommon | As a botanical extract it carries sensitization potential; reactions more likely in those allergic to Lamiaceae family plants. |
Photosensitivity | Rare | Some essential oil components may increase sensitivity to UV light, though oregano is not a strongly phototoxic botanical. |
Contact urticaria | Very rare | Isolated reports of immediate hypersensitivity reactions. |
