Allergen.
Both are on the published lists of the most common allergens. Many essential and aromatherapy oils contain natural ingredients that may smell and feel wonderful but are top allergens. This does not mean that you can’t use any of them…it means two things. First, if you have sensitive skin, opt or a non-allergen oil instead such as virgin coconut oil. Second, if you think you might have contact dermatitis, ask your dermatologist for a patch test. Your results will show exactly which essential oils and other ingredients you need to avoid…and which you can enjoy! To learn more about the difference between natural and hypoallergenic, click here.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.
