"Natural" is not a defined cosmetic ingredient but a marketing descriptor implying derivation from plant, mineral, or animal sources rather than synthetic processes. It has no regulatory standard in most regions and provides no inherent indication of safety, efficacy, or skin compatibility.

| Allergic contact dermatitis | Uncommon | Botanical-derived ingredients (e.g., essential oils, plant extracts) labeled natural can be common sensitizers. |
| Irritant contact dermatitis | Uncommon | Some natural extracts and oils may irritate sensitive or compromised skin. |
| Photosensitivity | Rare | Certain natural components such as citrus or furocoumarin-containing botanicals can increase UV sensitivity. |
| Anaphylaxis or severe allergic reaction | Very rare | Reported with potent botanical allergens in highly sensitized individuals. |
