For adults and older teens, thyme extract on the skin is usually low risk. Most grown-ups can use products that contain it, but some people may get a skin reaction such as redness, itching, or a rash.
If you are an adult planning to use a product with thyme extract: do a small patch test on the inside of your forearm and wait 24–48 hours before using it more widely. Avoid applying it to broken or irritated skin. If you have a known plant or thyme allergy, choose products without this ingredient. Limit using multiple products that all contain thyme extract to reduce total exposure.
Thyme has been identified as a possible human skin allergen by regulatory bodies (for example, the EU Cosmetics Directive and the European Chemicals Agency). There is also limited evidence of skin irritation or allergy and the ingredient is used in food (US FDA notes its use in foods), so you may get exposed from more than one source. Because some product certification programs restrict its use unless manufacturers show safety data, look for clear labeling and stop use and see a doctor if you get swelling, spreading redness, blisters, or breathing difficulty after exposure.
