Quick Summary
Synthetic fragrances are lab-made scent compounds and the most common cause of allergic contact dermatitis in cosmetics. Reactions include redness, itching, stinging, rashes, headaches and asthma, and repeated exposure builds a reaction over time. Dropping fragrance from your routine often lets reactive skin settle.
- Parfum and fragrance are catch-all label terms that can hide dozens of scent chemicals.
- Linalool and limonene are fragrance allergens commonly listed alongside a general parfum entry.
- A proper patch test takes 48 to 72 hours on the inner forearm or behind the ear.
- Scent is the smell something has, whether naturally occurring or added.
- Fragrance usually refers to ingredients added to give a product a particular smell. These can be natural, synthetic or a mixture.
- For skincare, fragrance-free doesn’t necessarily mean scent-free. Ingredients have their own smell. Essential oils are added for their therapeutic benefits, not their scent in the case of OmMade Organic Skincare.

What Makes Synthetic Fragrances in Skincare Risky
Synthetic fragrances are lab-made scent compounds added to skincare to make it smell pleasant. The dangers of synthetic fragrances in skincare come down to one fact: fragrance is the most common cause of allergic contact dermatitis in cosmetics. Many people find their skin settles once they drop fragrance from their routine.
A 2023 review by Rádis-Baptista and co-authors linked fragrance chemicals to skin, breathing and whole-body reactions, including headaches and asthma. A 2025 review by Alblooshi and co-authors raised further concerns about allergies, hormone disruption and respiratory issues. For deeper research on phthalates, fragrance and reproductive health, including the personal story behind OmMade Organic Skincare, explore our dedicated article.
The industry pushback is worth knowing. The International Fragrance Association says fragranced products are tested for irritation and sensitisation, and are safe for most people. If your skin is reactive, "most people" is not a useful benchmark.
Watch out: "fragrance-free" on a label does not always mean scent-free. Some products use masking fragrances to hide the smell of raw ingredients.
How to Spot Parfum on Skincare Labels
Parfum on a skincare label is a catch-all term. A brand can list scent chemicals under the single word "parfum" or "fragrance" without naming each one.
The Words That Hide a Fragrance
Here is what to scan for on the back of the bottle:
- Parfum or fragrance
- Aroma
- Essential oil blends
- Linalool, limonene, citronellol, geraniol, eugenol
- Coumarin and benzyl alcohol
Those last two lines matter. Linalool and limonene are fragrance allergens that are commonly listed alongside a general "parfum" entry. If you want to read labels with more confidence, our guide on how to buy handcrafted organic skincare online walks through spotting greenwashing.
Fragrance Allergy in Skincare: Signs You Should Not Ignore
Fragrance allergy in skincare usually shows up as redness, itching, stinging or a rash where you applied the product. It can also appear as swelling, hives or flaking. Symptoms may take hours or days to surface, which is why people blame the wrong product.
A 2025 review by Babayan and co-authors examined health risks linked to synthetic and semi-synthetic fragrances. The takeaway for everyday shoppers: repeated exposure is what builds a reaction over time.
Common signs to watch for:
- Burning or stinging within minutes of application
- Itchy patches on the cheeks, neck or eyelids
- Dry, scaly patches that will not settle
- New breakouts along the jawline
- Headaches or sneezing after applying a scented product
If two or more of these appear after a new product, stop using it.
How to Patch Test a New Face Serum
A patch test means applying a small amount of product to a small area of skin and waiting to see how it reacts. Done properly, it takes 48 to 72 hours and catches most reactions before they hit your whole face.
Here is the process we recommend:
- Choose the spot. Inner forearm or behind the ear. Not your face.
- Cleanse and dry the area.
- Apply a small amount the size of a grain of rice.
- Leave it uncovered for 24 hours. Do not wash it off.
- Check at 24, 48 and 72 hours for redness, itching or bumps.
- Stop immediately if anything appears.
For a full walkthrough, see our step-by-step guide on how to patch test a new face serum.
Watch out: testing on your jawline "because that is where you break out" defeats the purpose. A reaction on your jaw is harder to calm than one on your forearm.
A proper patch test takes 48 to 72 hours and follows a simple sequence.

Why Fragrance-Free Skincare for Sensitive Skin Changes Everything
Fragrance-free skincare for sensitive skin removes the single most common trigger before it reaches your skin. That is not a small tweak. For reactive skin, it is often the difference between a routine that works and one that keeps setting you back.
Our entire OmMade Organic Skincare range is free from fillers, synthetic fragrance and palm oil.
What most guides miss is that "unscented" and "fragrance-free" are different claims. Unscented products can still contain masking fragrance. Fragrance-free means no scent added at all. Synthetic Fragrance-free means there is naturally occurring scents but no added synthetic fragrance.
A simple checklist before you buy:
- Ingredient list has no "parfum" or "fragrance"
- No "aroma" listed
- Brand states "fragrance free" on the pack, not just "unscented"
- Full ingredient list is published, not hidden behind "proprietary blend"
What to Do If a Fragranced Product Causes a Reaction
Stop using the product the moment you notice a reaction. Wash the area with lukewarm water and a plain, fragrance-free cleanser. Do not scrub, and do not apply another active on top.
Then simplify. For the next week, use only a gentle cleanser and a plain moisturiser. Our article on how to treat skin barrier damage covers the full recovery process.
Skip these while your skin settles:
- Exfoliants and retinoids
- Hot showers
- Scented body wash or laundry detergent
- New products of any kind
If swelling, blistering or breathing trouble occurs, seek medical help immediately. For mild reactions, most skin settles within one to two weeks of removing the trigger.
Building a Fragrance-Free Routine with OmMade
Building a fragrance-free routine does not mean replacing everything at once. Start with the products that sit on your skin longest: cleanser, serum and moisturiser.
Our Kakadu Plum Face Moisturiser with Tallow & Geranium is a concentrated, fragrance free formula designed for sensitive, dry or reactive skin, and it carries a 4.9 out of 5 star rating from 90 reviews. The Botanical Overnight Repair Serum is a water-free facial oil made with castor oil and botanical extracts.
Both are naturopath formulated, made in small batches, and free from fillers and synthetic fragrance.
If you have been using another brand and it is working "okay", the question worth asking is whether your skin could be calmer without fragrance in the mix. That is the test we would run.
Most people never connect their skin flare-ups to the fragrance in their products, and that is exactly why the cycle keeps repeating. At OmMade Organic Skincare, we formulate every product without synthetic fragrance, fillers or palm oil, using a naturopathic approach that supports your skin barrier rather than testing it. Every order is backed by our 30-day money back guarantee. Get started with OmMade Organic Skincare and give your skin the calm, simple care it has been asking for.
Frequently Asked Questions
What are the possible dangers of synthetic fragrances in skincare?
Reviews of fragrance chemicals report cutaneous, respiratory and systemic effects, including headaches, asthma and skin irritation. A 2023 review by Rádis-Baptista and co-authors describes these reported effects, and a 2025 review by Alblooshi and co-authors lists allergies, respiratory issues and endocrine concerns among reported problems with perfumed cosmetics. The research does not establish that every person will react, and the International Fragrance Association maintains that fragranced products are safe for most people. For sensitive or acne-prone skin, the practical risk is irritation and allergic contact dermatitis.
How can I tell if a skincare product contains synthetic fragrance?
Turn the bottle over and read the full ingredient list, not the front label. In Australia, fragrance appears as parfum, fragrance or aroma, and individual scent chemicals such as linalool or limonene may be listed separately. Words like natural fragrance or essential oil blend still describe added scent, so they are not the same as fragrance free. If the label claims fragrance free but lists parfum, treat the claim with suspicion and ask the brand directly.
How do I patch test a new face serum?
Apply a small amount to the inner forearm or behind the ear, leave it for 24 to 48 hours, and watch for redness, itching or swelling. If nothing appears, test a small patch on the jawline before using it across the whole face. Stop at the first sign of irritation and wash the area with cool water. Keep the product's batch details so you can identify it if a reaction develops later.
What should I do if a fragranced skincare product causes a reaction?
Stop using the product immediately and rinse the area with cool water. Avoid adding other new products while the skin settles, and note the ingredients so you can compare them with future purchases. If the reaction is severe, spreading or does not settle within a few days, see a doctor or pharmacist. For ongoing sensitivity, switch to fragrance-free skincare for sensitive skin and patch test every new serum before full use.
