Skin Care Ingredients That Cause Allergic Reactions on the Face
There are many skin care ingredients that cause allergic reactions on the face. The only way to prevent this from happening again is to figure out which ingredients caused the rash. Then, you can read product labels to avoid that ingredient.
If you have had a face allergy to a skin cream or new skincare product, you know how uncomfortable the skin inflammation from a skin allergy can be. Whether you have tiny bumps on the face, redness, swelling, hives or itching, the treatment is the same. You need to soothe and calm the skin and avoid the allergenic ingredient.
You can treat the face allergy with anti-inflammatory and soothing ingredients.
However, you must figure out what skin care ingredients in your skin care products that caused the skin allergy.
Cosmetic Ingredients That Cause Allergies
If you have an allergic reaction on your face, chances are it is one of these 6 types of ingredients that are causing it. A rash on the eyelids is almost always due to nail polish, while a rash on the hands is usually hand soap. An allergic reaction on the face can be caused by many ingredients, but fragrances and preservatives are the most common.
The 6 most common ingredients in skin care products that cause allergic reactions on the face are:
Fragrances
Essential Oils
Preservatives
Plant derived ingredients
Chemical sunscreens
Parabens
How To Figure Out What Skin Care Ingredients I Am Allergic To?
If you suffer from a skin allergy from a skin care product you have three choices:
Figure out what you are allergic to by keeping a diary
See a dermatologist and get patch testing
Find a skincare brand that is hypoallergenic
If you get an allergic reaction, start a diary and write down every ingredient on the ingredient list in any skin care products that you used over the last 48 hours. Then match the list to these common allergen lists. Below you can find lists of the most common allergens in skin care products.
Circle the items in your diary that are on the allergenic ingredient list.
With time you will notice a pattern and will see that it is always the same ingredient that is giving you a rash.
You can also find a dermatologist at aad.org and get a patch test (Not all dermatologists do patch testing so ask before you schedule an appointment).
Hypoallergenic Skin Care Brands
Our favorite hypoallergenic skincare brands are:
VMV Hypoallergenics- was developed by a dermatologist and does not have the 100 most common allergens in it.

niacinamide chemical structure
Allergy to Niacinamide
Niacinamide can cause a skin allergy. We have see happen with EltaMD UV Clear SPF and other niacinamide containing products.
Rag Weed Allergy
If you have a ragweed allergy, certain skincare ingredients may cause cross-reactions due to their botanical relations or similarity in allergenic components. It’s essential to be cautious and potentially avoid ingredients that are in the same family as rag weed.
Skin care ingredients to avoid if you have a ragweed allergy:
Chamomile – This popular soothing ingredient is related to ragweed.
Echinacea – Often used for its anti-inflammatory properties.
Marigold (Calendula) – Used for its soothing and healing properties.
Sunflower oil – Sometimes found in moisturizers and other skincare products.
Helenium – Used in some herbal skincare products.
Dandelion extract – Occasionally used in natural or botanical products.
Tansy oil – Found in some herbal formulas.
Yarrow – Used for its astringent properties.
Artemisia – Another name for this is wormwood or sagebrush, and it’s sometimes used in skincare.
Bisabolol, a compound found in many plants
Allergy to Preservatives
If you have a preservative allergy, certain preservatives in skincare and cosmetic products can cause allergic reactions.
Skin care ingredients to avoid if you have a preservative allergy:
Parabens (e.g., methylparaben, ethylparaben, propylparaben, butylparaben)
Formaldehyde and formaldehyde-releasing preservatives:
Quaternium-15
DMDM hydantoin
Imidazolidinyl urea
Diazolidinyl urea
Polyoxymethylene urea
Sodium hydroxymethylglycinate
Methylisothiazolinone (MIT) and Methylchloroisothiazolinone (CMIT)
Benzyl alcohol
Phenoxyethanol
Bronopol (2-bromo-2-nitropropane-1,3-diol)
Isothiazolinones
Thimerosal
Triclosan and Triclocarban
Propylene glycol and butylene glycol (though these are more commonly classified as irritants, they can sometimes cause allergic reactions)
Methyldibromo glutaronitrile/phenoxyethanol (Euxyl K 400)
Benzyl alcohol
Fragrance Allergy
If you have a fragrance allergy, you should be aware that fragrances are among the top five allergens in cosmetics and other products. People sensitive to fragrances should look out for a wide array of ingredients, as the term “fragrance” or “parfum” in an ingredient list can actually be a blend of many components.
What skin care ingredients to avoid if you have a fragrance allergy:
Fragrance or Parfum: A catch-all term that can refer to a blend of multiple fragrance ingredients.
Linalool
Limonene
Eugenol
Cinnamal (Cinnamaldehyde)
Geraniol
Isoeugenol
Coumarin
Citral
Benzyl Alcohol (not always used as a fragrance but can be present in some fragrant blends)
Benzyl Salicylate
Benzyl Benzoate
Farnesol
Citronellol
Hexyl Cinnamal
Amyl Cinnamal
Cinnamyl Alcohol
Oakmoss and Treemoss Extracts (Evernia prunastri and Evernia furfuracea)
Balsam of Peru (or Myroxylon pereirae) – it’s both a fragrance and flavoring agent, and can be found in many products.
Essential oils – even though they’re natural, they can still cause reactions in sensitive individuals. Lavender, peppermint, tea tree, and ylang-ylang are common essential oils in skincare products.
Additionally, “unscented” products might still contain fragrances to mask the scent of other ingredients. If you’re sensitive, opt for products labeled “fragrance-free.”
Remember, sensitivity to one fragrance ingredient doesn’t mean you’ll react to them all. But given the complexity and lack of transparency in fragrance formulations (they’re considered trade secrets), many people with fragrance allergies opt to avoid all fragranced products.

Our advice is to write down everything you put on your face in the last 12 hours. With time you will start to see a pattern and this can help you narrow down which ingredients caused the reaction. You can also see a dermatologist and get patch testing done to identify the exact allergens.
It is so difficult to figure out what you are allergic to. You may even be allergic to more than one skin care ingredient. So if this is a concern for you- get patch testing done by your dermatologist. It will make buying skin care so much easier for you!
