adults • Skin contact product
For adults (including teens), arnica flower extract applied to the skin is usually low risk. The main worry is that some people can get a skin allergy or irritation.
Before using a new product with arnica, do a small patch test on the inside of your forearm and wait 24–48 hours. Don’t put it on cuts, open wounds or broken skin. Stop use and wash the area if you get redness, itching, swelling or a rash. If you are pregnant, breastfeeding, or taking medicines that affect bleeding, check with your health care provider before use.
Watch for allergic skin reactions — a cosmetic safety review found strong evidence that arnica can be a skin allergen. There are also some gaps in safety data according to the same review. The U.S. Food and Drug Administration lists it as safe only in limited food uses, which is different from applying concentrated extracts to the skin. Avoid use on broken skin and do not ingest concentrated arnica products.
