These two labels get treated as interchangeable, but for sensitive and reactive skin, the distinction is one of the most useful things you can learn to check on a product label.
Fragrance-free
This means no fragrance ingredients — including essential oils used for scent — have been added to the formula at all. This is the safer claim for reactive skin, though it’s worth noting the term isn’t strictly regulated, so checking the actual ingredient list for “fragrance,” “parfum,” or specific essential oil names is still worthwhile.
Unscented
This means the product has no perceptible scent to the user — but it can still contain fragrance ingredients added specifically to mask the smell of other ingredients in the formula. In other words, “unscented” can describe a product that contains fragrance compounds, just blended to cancel out rather than add a noticeable smell.
Fragrance — including masking fragrance in “unscented” products — is one of the most common topical sensitizers and a frequent cause of allergic contact dermatitis. If you react to “unscented” products despite avoiding obviously scented ones, masking fragrance is a common, often-overlooked culprit.
How to actually check
- Look for “fragrance” or “parfum” anywhere in the ingredient list, not just on the front label
- Watch for specific essential oil names (lavender, citrus extracts, tea tree) even in products that don’t use the word “fragrance”
- “Fragrance-free” claims are more reliable than “unscented” or “natural fragrance” claims for reactive skin
