Sensitive skin is one of the most searched makeup concerns in the UK — and one of the most exploited by marketing. Walk into any pharmacy or Boots and you will find shelves of products labelled "gentle", "hypoallergenic", "dermatologist tested", and "for sensitive skin." Most of those labels are unregulated. None of them legally require the brand to have removed any specific ingredient, conducted any standardised testing, or changed the formula in any meaningful way.
If your skin keeps reacting to makeup, the label is not the problem. The ingredients are. And the most common culprit — by a significant margin — is one that appears in the majority of makeup products sold in the UK, including many that carry sensitive skin claims on the front of the pack.
It is fragrance.

The Fragrance Problem
Synthetic fragrance — listed as "parfum" or "fragrance" on the INCI ingredient list — is not a single ingredient. It is a catch-all term that can represent a blend of dozens or hundreds of individual chemicals, none of which the brand is required to disclose individually. It is the leading cause of cosmetic contact dermatitis and the first ingredient to look for when a product is causing a reaction.
Essential oils are the same problem in a different package. Many "natural" sensitive skin formulas swap synthetic fragrance for lavender oil, citrus extracts, or eucalyptus — all of which are common sensitisers for reactive skin. Natural does not mean non-irritating. For genuinely sensitive skin, fragrance-free means no fragrance of any kind, synthetic or botanical.
What Else Sensitive Skin Reacts To
Alcohol Denat
Drying and barrier-disrupting. Common in primers and setting sprays. Worth avoiding for reactive skin.
Methylisothiazolinone (MI)
A preservative and significant sensitiser. Restricted in EU leave-on products — hard flag in our standard.
Essential Oils
Lavender, citrus, eucalyptus, and peppermint are all common sensitisers. Particularly prevalent in "natural" sensitive skin ranges.
EU Fragrance Allergens
26 individual fragrance chemicals must be declared by name on INCI lists above certain concentrations. If these appear in a "sensitive skin" product, the claim is not credible.
What "Hypoallergenic" Actually Means
Nothing legally enforceable. Like clean and non-toxic, hypoallergenic has no regulated definition under UK or EU cosmetics law. A product labelled hypoallergenic that contains synthetic fragrance is a product with a misleading label.
e.l.f. Velvet Finish Face Primer — £11.00
A fragrance-free, silicone-based primer that sits well under foundation without disrupting a compromised skin barrier. The Velvet Finish passes our full review with no hard or soft flags — in the primer category, where alcohol denat and fragrance are near-universal, that is a genuinely clean result. e.l.f. is widely available in Superdrug, Boots, and Primark across the UK.
Catrice Nude Drop Tinted Serum Foundation — £9.11
A tinted serum rather than a traditional foundation — lighter in texture, shorter ingredient list, and significantly better tolerated by reactive skin. Fragrance-free, no hard flags, and formulated with hyaluronic acid and niacinamide. The serum format is worth understanding: less pigment load, less coverage, but far less formula contact with reactive skin. At £9.11 it is one of the best-value sensitive skin foundations in our database.
Essence Skin Lovin' Sensitive Concealer — £5.14
Essence named this range honestly — the Skin Lovin' Sensitive line is genuinely formulated with reactive skin in mind. The concealer is fragrance-free, passes our full ingredient review with no flags, and is one of the most consistently recommended products in our database for sensitive skin. At £5.14 it is also the most affordable pick on this list.
BPerfect IntensifEYE Mascara — £15.95
BPerfect is an Irish brand with a strong following across the UK and Ireland. The IntensifEYE passes our full ingredient review for sensitive eyes — fragrance-free, no hard flags, and formulated without the preservative and pigment ingredients that most commonly cause eye irritation. The direct brand links below are the best route for UK shoppers.
Full sensitive skin face — four products, zero fragrance
£41.20
Primer, foundation, concealer, and mascara — all fragrance-free, all vetted, all recommended.

Frequently Asked Questions
Fragrance — by a significant margin. Synthetic fragrance (listed as "parfum" or "fragrance" on the INCI) is the leading cause of cosmetic contact dermatitis. It appears in the majority of makeup products sold in the UK, including many carrying sensitive skin claims on the label.
No. Hypoallergenic has no regulated definition under UK or EU law. A brand can use it on any product without removing any specific allergen or conducting standardised testing. Check the ingredient list, not the label.
Not automatically. Essential oils — lavender, citrus, eucalyptus — are common sensitisers for reactive skin and appear frequently in natural formulas. Fragrance-free means no fragrance of any kind, synthetic or botanical, and is the more reliable standard for genuinely sensitive skin.
Fragrance-free means no fragrance ingredients were added. Unscented means masking fragrances may have been used to neutralise the natural smell of the formula — those masking agents can still trigger reactions. For reactive skin, fragrance-free is the safer choice.
