Fragrance-free vs unscented: what labels mean

The American Academy of Dermatology (AAD) gives the two labels different meanings. Unscented means a fragrance is masked, so you cannot smell it. Fragrance-free means the product is free of all fragrances, even ones you cannot smell. For sensitive skin, the AAD advises choosing fragrance-free. The US Food and Drug Administration (FDA) adds a fact that limits how far you can trust either word: no federal standard or definition covers "fragrance-free", "hypoallergenic" or "for sensitive skin". This guide explains what each label word means, what US rules require on a cosmetic label, and how to read the ingredient list. It is part of Skinli's guide to sensitive skin.

Skinli gives general education and is not a doctor. Skinli has tested no product, so this page names no brand. When a label word and the ingredient list seem to disagree, trust the ingredient list, because it is the part of the label that FDA rules require.

The label words at a glance

Label word	Legal meaning in the US	What the AAD says
Fragrance-free	None. The FDA says no federal standard defines it	Choose it for sensitive skin
Unscented	None found in the sources read for this guide	The fragrance has been covered up and can still cause an allergic reaction
Hypoallergenic	None. The FDA says it means whatever a company wants it to mean	Less risk, though a reaction can still happen
For sensitive skin	None. The FDA says no federal standard defines it	People with sensitive skin should look for these words
Dermatologist tested	No source read for this guide defines it	The AAD says "clinically proven" means the product was given to consumers to try
Natural or clean	None. MedlinePlus says "natural" has no official meaning	These products can still cause a skin reaction

What "fragrance-free" means

The AAD's page for men gives its advice in one sentence: "If you have sensitive skin, use mild, 'fragrance free' products, as products containing fragrances can leave skin feeling irritated and dry." Its page on testing products says the same for anyone who reacts: "if fragrance in skin care products is causing your skin to react, opt for products that are labeled 'fragrance free.'" A 2025 AAD news release quotes a dermatologist who says fragrance-free products are best "because added scents can trigger irritation or allergic reactions".

The label itself carries no legal promise. The FDA's page on allergens in cosmetics says: "It isn't enough to check for terms like 'hypoallergenic', 'fragrance-free' or 'for sensitive skin,' as there is no federal standard or definition". A 2003 review of fragrance allergy went further. It found that "products labelled as 'fragrance free' have also been shown to contain fragrance ingredients". The review gave the reasons: fragrance ingredients used "as preservatives or masking perfumes, or the use of botanicals." Botanicals are plant extracts.

The FDA and the AAD fit together on this point. The FDA's fragrance page says: "if you are concerned about fragrance sensitivities, you may want to choose products that are fragrance free, and check the ingredient list carefully." So choose fragrance-free, as the AAD advises, and then read the list, as the FDA advises.

What "unscented" means

An unscented product can still contain fragrance. The FDA says: "Even some products labeled 'unscented' may contain fragrance ingredients." It explains why: "the manufacturer may add just enough fragrance to mask the unpleasant smell of other ingredients, without giving the product a noticeable scent."

AAD pages describe the same thing in four places:

• "If you see 'unscented' on the label, it means the fragrance in a product has been covered up."
• "A fragrance that's been covered up can still cause an allergic reaction."
• An unscented product "can contain chemicals that neutralize or hide the odors of other ingredients. These chemicals can irritate dry, sensitive skin."
• Balsam of Peru is "A fragrance used in cosmetics and personal care products, used in 'unscented' products to cover up a fragrance".

For rosacea, which often makes skin sensitive, the AAD's advice is short: "choose fragrance-free (rather than unscented) products." Its rosacea advice on sunscreen goes one step further: if a sunscreen label says unscented, choose another sunscreen. The rosacea guides on Skinli, such as skincare for rosacea, cover that condition in full.

The two words describe different things. Unscented describes the smell. Fragrance-free describes what is in the product.

Why fragrance matters for sensitive skin

The AAD calls fragrance "one of the most common causes of contact dermatitis". Contact dermatitis is a rash caused by something that touches the skin. The AAD says "More than 15,000 things that touch our skin can cause an allergic reaction", and that "Some of the more common ones are fragrance and nickel, which are found in hundreds of products and everyday items." MedlinePlus, writing about cosmetics, says: "Fragrances and preservatives are the most common causes of skin problems."

Estimates of how many people are allergic to fragrance differ between reviews:

• A 2003 review: 1.7 to 4.1 percent of the general population are allergic to the fragrance mix, a set of common fragrance ingredients used in allergy tests. The same review says fragrance allergy "occurs predominantly in women with facial or hand eczema."
• A 2020 review: "The prevalence of fragrance allergy in the general population is between 0.7% and 2.6%." Among people sent for allergy patch tests, 5 to 11 percent react to fragrances.

The 2003 review put the number of fragrance ingredients used in perfumes at 2,500, an estimate, and said at least 100 of them are known contact allergens.

A fragrance allergy can start late. MedlinePlus says a person can use a substance with no trouble for years, even decades, before an allergy starts, and that an allergy, once it starts, lasts for life. The AAD says an allergy to fragrance can cause a rash "where you apply a personal care product." Fragrance in makeup and in laundry detergent is covered in makeup for sensitive skin and laundry detergent for sensitive skin.

What "hypoallergenic" means

Start with the FDA, because it is the agency that writes US cosmetic label rules:

• "There are no Federal standards or definitions that govern the use of the term 'hypoallergenic.'"
• "The term means whatever a particular company wants it to mean."
• Companies that use the word do not have to send the FDA proof that their products cause fewer allergies.
• No cosmetic can be guaranteed never to cause an allergic reaction.
• In a 1978 article on its page, the FDA said it knew of no scientific studies showing that hypoallergenic cosmetics cause fewer reactions than other products.

MedlinePlus agrees: "Labels such as 'natural' and 'hypoallergenic' have no official meaning. Companies can use them to mean whatever they want."

The AAD still treats the word as a useful first check. Its page on choosing anti-aging products lists "Hypoallergenic (The product can still cause an allergic reaction, but there is less risk)". Another AAD page says: "Even hypoallergenic products can cause a skin reaction." For a rash around the eyes, the AAD says: "Switching to a hypoallergenic product may prevent a new rash."

"For sensitive skin", "dermatologist tested" and "natural"

For sensitive skin. The AAD says: "If you have sensitive skin, you want to see the words 'sensitive skin' on the label." It also says gentle products "are often labeled 'for sensitive skin.'" The FDA says no federal standard defines the phrase, and the AAD's sunscreen page says the FDA "does not define the term 'sensitive skin' for sunscreen." A 2002 study tested cleansers sold for dry skin on the forearms of 30 people with sensitive skin. It concluded: "Most products recommended for sensitive skin have a considerable irritation effect, which is related to the pH of the product." The pH is a measure of how acidic or alkaline a product is.

Dermatologist tested. No source read for this guide defines this phrase. The AAD explains a similar one: "'Clinically proven' means that the product was given to consumers to try." Every AAD page also says the academy "does not endorse companies or products."

Natural, organic and clean. The AAD says: "Even 'natural' or 'clean' skin care products can cause a skin reaction." The FDA says: "An ingredient's source does not determine its safety", and "many plants, whether or not they are organically grown, contain substances that may be toxic or allergenic." The AAD asks you to "Remain cautious" with products labeled unscented or made with "plant-based botanical ingredients, as these products may still have fragrance-related ingredients." It also warns that essential oils "may cause irritation or allergies", and the FDA says "There is no regulatory definition for 'essential oils.'"

How to read the ingredient list

The FDA says its rules "require the ingredients used in cosmetics to be listed on the product label, so consumers can avoid substances that have caused them problems." The rule, 21 CFR 701.3, sets the order: ingredients go "in descending order of predominance", which means the largest amount first. Ingredients present at 1 percent or less can be listed in any order.

Fragrance is the exception. The same rule lets a maker list it as the single word "fragrance". The FDA's allergen page says some ingredients may be listed "as 'fragrance,' or 'perfume,' without identifying the specific ingredients."

What to look for:

1. The words fragrance or perfume. Either one means added fragrance, whatever the front of the bottle says.
2. Named fragrance ingredients. The FDA lists fragrance allergens from a European list, such as linalool, limonene, citronellol, geraniol, eugenol and coumarin, and newer additions such as lavender, peppermint, rose, bergamot and lemon peel oils.
3. Preservatives. The FDA names methylisothiazolinone, methylchloroisothiazolinone and several preservatives that release formaldehyde, such as DMDM hydantoin and quaternium-15.
4. Anything you reacted to before. The FDA's advice is "carefully reading the product ingredient panel and avoiding ingredients you know or think you are allergic to."

US rules on fragrance labeling may change. A 2022 law, the Modernization of Cosmetics Regulation Act, requires the FDA to write rules for "Fragrance allergen labeling requirements." On 2026-10-17 the FDA's page on that law linked no final rule for it.

Test the product, then watch for a late rash

Even a fragrance-free product can cause a reaction, so test it. The AAD's method: "Apply the product to a test spot twice daily for seven to 10 days", on "a quarter-sized spot" such as "the underside of your arm or the bend of your elbow." The full method is in how to patch test a new skincare product. If a product stings as soon as it goes on, why does my skincare sting explains the common causes.

An allergic rash can appear late. The AAD says it "tends to appear hours or days after your skin touches what you're allergic to." The American Contact Dermatitis Society gives a range from a day to a couple of weeks. When you change products, the AAD advises: "Use one product for a week before adding the next one."

A dermatologist can find the cause with patch testing. The AAD says "You will leave the patches on your skin for 48 hours", then return after 4 to 7 days. After the test, a program of the American Contact Dermatitis Society called CAMP "can provide you with a list of safe products to use that is customized to your specific allergies."

See a doctor if a rash spreads, blisters, lasts, or keeps coming back. Get urgent care for swelling of the face or throat, hives with trouble breathing, or nausea or vomiting after using a product.
