Sensitive skin diagnosis

Skin that stings, burns or flushes with products usually has an identifiable cause, such as rosacea, seborrhoeic dermatitis or contact allergy, and diagnosis beats endlessly switching cosmetics.

Key points

What matters most, at a glance.

The essentials in plain English - symptoms, when to seek help, who to see and what treatment looks like.

  • True product allergy can be identified by patch testing

  • Rosacea and seborrhoeic dermatitis commonly masquerade as sensitive skin

  • Overloaded skincare routines and potent actives are frequent self-inflicted causes

  • Specialist: a consultant dermatologist, who can arrange patch testing where allergy is suspected

Understanding it

About Sensitive skin diagnosis, and what to do next.

Sensitive skin is a description, not a diagnosis: behind it usually sits an impaired barrier from over-cleansing or too many active ingredients, an inflammatory condition such as rosacea, seborrhoeic or perioral dermatitis, or genuine allergic contact dermatitis to a preservative or fragrance. Each has a different fix, which is why cycling through cosmetic ranges rarely works.

A useful reset is stripping the routine to a bland cleanser, moisturiser and sunscreen for six weeks while any underlying condition is treated, then reintroducing products singly. Patch testing formally identifies contact allergens, converting guesswork into a specific list of ingredients to avoid. Most people start with their GP, who can refer to a consultant dermatologist. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks depending on where you live, whereas an initial appointment with a private consultant is typically available within around two weeks.

Frequently asked

Common questions about Sensitive skin diagnosis.

Quick, plain-English answers to what people ask us most.

  • What causes sensitive skin?

    Skin that stings, burns or flushes with products usually has an identifiable cause, such as rosacea, seborrhoeic dermatitis or contact allergy, and distinguishing between them guides much more effective treatment than generic sensitive-skin products.

  • How is the cause of sensitive skin diagnosed?

    Diagnosis involves a careful history of triggers and product reactions, examination of the pattern of symptoms, and sometimes patch testing to identify a specific contact allergy.

  • Is sensitive skin always due to an allergy?

    No, sensitivity can stem from several different underlying conditions - rosacea and seborrhoeic dermatitis are common causes distinct from allergy - so identifying the specific driver matters more than assuming allergy alone.

  • How is sensitive skin treated once the cause is identified?

    Treatment is targeted to the specific underlying cause - anti-inflammatory treatment for rosacea, antifungal treatment for seborrhoeic dermatitis, or avoidance of a specific identified allergen for contact allergy.

  • Can sensitive skin products alone fix the problem?

    Generic sensitive-skin products can help avoid further irritation but rarely resolve the problem fully if there's an underlying condition like rosacea or seborrhoeic dermatitis driving the sensitivity, which needs specific treatment.

  • When should I see a dermatologist about sensitive skin?

    See a dermatologist if sensitive skin symptoms are persistent or not improving with simple product changes, so the specific underlying cause can be identified and properly treated.
