Flaking, scaling, and the patches that look alike.
Seborrhoeic dermatitis, psoriasis, eczema and rosacea can all show up as red, scaly skin on a face. They are confused constantly — including by people who have lived with one of them for years. This page describes what tends to be different. It will not tell you which one is yours, because that is a doctor's job, and here it matters more than almost anywhere else.
Four different things, one surface.
Skin has a small vocabulary. Whatever is happening underneath, the face has roughly the same handful of ways to show it — redness, scale, flaking, itch, heat. Four conditions with quite different causes and quite different treatments can therefore look remarkably similar in a mirror, and even more similar in a photo.
That is why people arrive having tried the wrong thing for a long time. Not because they were careless, but because the surface simply does not carry enough information to tell them apart.
Seborrhoeic dermatitis is common, chronic and tends to sit where skin is oiliest. Psoriasis is an immune condition with a different kind of scale. Eczema is a barrier and inflammation problem that usually itches first. Rosacea is a vascular and inflammatory pattern that often flushes before anything else happens. Those are general descriptions of conditions, not descriptions of you.
What usually differs.
Every line below is a tendency, not a rule, and there are people who break all of them. Read it as background for a conversation with a doctor, never as a way of reaching an answer without one.
- Where it sits
- Seborrhoeic dermatitis characteristically favours oily areas — the creases beside the nose, the brows, behind the ears, the scalp and sometimes the chest. Psoriasis more often appears on elbows, knees, the scalp margin and the lower back. Eczema is common in the folds of elbows and knees, on hands, and around the eyes. Rosacea concentrates on the central face: cheeks, nose, chin, forehead.
- What the scale looks like
- Seborrhoeic scale is typically fine, greasy and yellowish. Psoriasis scale is more often thick, dry and silvery, sitting on a well-defined plaque with a clear edge. Eczema tends to flake more finely and may weep or crust when it is bad. Rosacea often has no scale at all — which is one of the more useful distinctions.
- Where the border is
- Psoriasis plaques usually have an edge you could trace. Seborrhoeic dermatitis and eczema tend to fade into surrounding skin without a defined boundary. It is a small detail that clinicians notice early.
- What it feels like
- Eczema itches, often intensely, and often before anything is visible. Psoriasis can itch but is more often described as tight or sore. Seborrhoeic dermatitis is frequently more irritating than itchy. Rosacea is more commonly described as burning, stinging or hot.
- What it does over time
- Seborrhoeic dermatitis classically comes and goes, and many people find it worse in colder months or under stress. Psoriasis tends to persist in the same places. Eczema often has a long history going back to childhood. Rosacea usually starts with flushing that becomes more frequent and lasts longer.
- What else is going on
- Nail changes, joint pain, a family history, hay fever or asthma, and how skin behaves elsewhere on the body all carry information that a face on its own does not. This is a large part of why identification belongs to someone taking a full history.
This is a pattern, not a test. Two of these can occur together, and a person can have one of them and something else entirely at the same time.
The name changes the whole answer.
For most skin concerns, getting the label slightly wrong costs you time. Here it can cost you years.
These conditions are treated differently from one another, and several of them respond to prescription treatments that are inexpensive and that a GP can write in a single appointment. It is entirely possible to spend a great deal on skincare and in-clinic treatments for something that a modest tube from a pharmacy would have settled — and to conclude, wrongly, that your skin is simply difficult.
We would rather say that plainly than have you find out later. If what you are describing sounds like it belongs to a doctor, we will tell you so at the consultation, and that will be the most valuable part of it.
Being told no is not being turned away.
If you arrive with skin that is actively inflamed, flaking or broken, a nurse here will very likely decline to treat it that day. It is worth knowing why before you book, because it is not a judgement about you and it is not uncertainty.
Nearly everything a skin clinic does works by disrupting the surface in a controlled way — peels, needling, dermaplaning, microdermabrasion. On settled skin that is the point of them. On skin that is already inflamed, the same disruption lands on a barrier that is not in a position to absorb it, and the usual result is a longer, angrier flare than you started with.
So the reasoning is not we don't know what this is. It is we can see this is inflamed, and our instruments make inflamed skin worse. That is a straightforward call, and a nurse does not need a diagnosis to make it — a diagnosis is what you need in order to treat something, never in order to wait.
What actually happens is that you keep the consultation, you keep the written plan for everything else, and you leave with a reason, a referral if you want one, and a point at which to come back. One treatment on one day is deferred. Nothing else is.
This is also why we ask about diagnosed skin conditions before your appointment rather than at it. Nobody should discover this in the chair.
What a skin clinic can honestly offer.
Once a condition has been identified and is being managed by whoever treats it, there is real work here — it is simply not the work people assume.
- Reviewing what you are already using
- This is the most common finding and the least expensive fix. People with reactive, flaking skin are very often using several actives at once — acids, retinoids, strong cleansers — because flaking reads as something to exfoliate. Frequently the routine is part of the pattern, and removing things helps more than adding them.
- Barrier support between flares
- Skin that is prone to this does better when its barrier is in good order. That is a skincare and habit conversation, not a procedure, and it is a legitimate thing to plan carefully.
- Gentle treatment when skin is settled
- A hydrating facial without abrasion is often available between flares where a peel or needling is not. Timing matters more than choice of treatment here.
- Working around affected areas
- A flare confined to the creases beside the nose does not necessarily rule out work elsewhere on the face. That is a judgement made on the day, by the nurse who is looking at it.
- Telling you when to go elsewhere
- Included at no extra charge and offered more often than people expect. If the honest answer is a GP or a dermatologist, that is the answer you get.
What is not on this list: treating seborrhoeic dermatitis, psoriasis, eczema or rosacea. Those are medical conditions and they are treated by doctors. We do not treat them, and a clinic that tells you otherwise is selling you something.
The order that usually works.
A GP first, then us — not because we are being cautious, but because that sequence is faster and cheaper for you than the reverse.
Ninety minutes and a written plan. If part of that plan is "see your GP about this first", it will say so, and the rest of the plan still stands.

Seborrhoeic keratosisAlmost the same name, an entirely different thing — a benign growth rather than an inflammatory condition. Worth reading if you have been searching both.

Asked about flaking skin.
Answered the way they would be answered in the room.
Can you get a facial if you have seborrhoeic dermatitis?
Often yes, when the skin is settled — and usually no while it is actively flaring. Most facial treatments work by disrupting the skin's surface, which is useful on calm skin and counterproductive on inflamed skin. A hydrating facial without abrasion is more likely to be available than a peel or needling. The decision is made by the nurse looking at your skin on the day, not booked in advance.
What is the difference between seborrhoeic dermatitis and psoriasis?
Generally, seborrhoeic dermatitis favours oily areas such as the creases beside the nose, the brows and the scalp, with fine greasy yellowish scale that fades into the surrounding skin. Psoriasis more often appears on elbows, knees and the scalp margin, with thicker silvery scale on a plaque that has a defined edge. Both can appear on the scalp and both can look alike early on, which is why telling them apart is a doctor's job rather than something to settle from a photograph.
Is seborrhoeic keratosis the same as seborrhoeic dermatitis?
No. The names are almost identical and the conditions are unrelated. Seborrhoeic keratosis is a benign growth — a raised, often waxy spot that looks stuck onto the skin and accumulates with age. Seborrhoeic dermatitis is an inflammatory condition producing red, flaking patches. They share a word because both were historically associated with oily areas, and that is the extent of the connection.
Does microneedling help rosacea?
It is not a treatment for rosacea, and rosacea is a medical condition managed by a doctor. Microneedling deliberately creates controlled injury, which skin prone to flushing and inflammation frequently does not tolerate well, so it is often not appropriate. Some people with well-controlled rosacea can have it for a separate reason such as texture or scarring, but that is an individual assessment and the honest answer for many is no.
What is facial dandruff?
It is the everyday name for fine flaking on the face, most often around the nose, brows and hairline. It is usually describing seborrhoeic dermatitis in a place other than the scalp, since scalp dandruff and this are generally regarded as the same process. It is not caused by poor washing, and scrubbing at it typically makes it worse.
Can a skin clinic treat eczema or psoriasis?
No. Both are medical conditions and treating them is a doctor's work, often with prescription treatments a skin clinic cannot provide. What a skin clinic can do is review the products you are using, support the barrier between flares, and time other treatments around the condition rather than through it. Any clinic advertising treatment for these conditions is describing something it is not in a position to deliver.
Why won't you treat me while my skin is flaring?
Because the treatments available here work by disrupting the skin's surface in a controlled way, and skin that is already inflamed responds to that by flaring longer and harder. A nurse does not need to know which condition it is to make that call — a diagnosis is required in order to treat something, not in order to wait. You keep your consultation and your plan; one treatment on one day is deferred.
Should I exfoliate flaking skin?
Flaking looks like something to remove, which is why so many people reach for acids and scrubs, and it is one of the most common patterns we see. If the flaking is coming from an inflammatory condition, exfoliating removes a barrier that is already struggling and the flaking usually returns worse. If it is simple dryness the answer is different. Working out which is which is most of the value of an assessment.
