ARN

3/10

Concern level

Low concern

A botanical extract from Arnica montana, traditionally used for its anti-inflammatory-leaning cosmetic and medicinal reputation. PubChem and CIR identify Arnica montana extract as a plant extract; the CIR safety review concluded the available data were insufficient to support safety in cosmetic formulations.

Interactions

incompatible with: Avoid combining with other common sensitizers or strong exfoliating/irritating actives on compromised skin, since arnica can amplify irritation in reactive users.

Risks & Warnings

Arnica is a well-known sensitizer and may cause contact dermatitis, stinging, or redness, especially on broken, irritated, or compromised skin. Because CIR found the data insufficient for cosmetic safety, it should be used cautiously and avoided by anyone with a history of botanical allergy.
