Read your skin before you read a label
Almost every expensive mistake starts with a self-diagnosis made in four seconds in front of a mirror. Oily is a symptom with at least four causes, and three of them get worse if you buy for the wrong one.
We sell some of what is named here
Routinae sells some of the products written about here, so read this the way you would read any shop’s opinion of its own shelves. Where we think a cheaper product does the same job we say so, and where the evidence is thin we say that too. Our buying standard is published so you can check the argument against it.
Almost every expensive skincare mistake starts the same way: with a self-diagnosis made in four seconds in front of a mirror. I have oily skin. I have sensitive skin. I have dry skin.
Those sentences feel like facts. Mostly they are conclusions — and the product you buy next is chosen to match the conclusion rather than the skin.
Oily is a symptom, not a diagnosis
Take the most common one. Your face is shiny by mid-afternoon, so you buy for oily skin: a foaming cleanser, an astringent toner, a mattifying gel. Shine is a symptom with several plausible causes, and only one of them responds to that shelf.
It might be that your skin genuinely produces a lot of sebum, which is a stable trait and largely genetic. It might be that your skin is short of water rather than oil, which is a condition and can change in a fortnight. It might be that you have been cleansing so thoroughly that you strip the surface every night. It might be seasonal, or hormonal, or the fact that you started a new product three weeks ago and never connected the two.
Three of those four get worse on a routine built for the first one. That is the cost of diagnosing from a single symptom: not wasted money, but time spent making the actual problem worse while believing you are treating it.
Type and condition are different things
This distinction does more work than any ingredient you will read about this year.
Skin type is roughly stable. How much oil your skin produces, how thick it is, how quickly it flushes. It changes over years, not weeks. It is worth knowing once.
Skin condition is what your skin is doing this month. Dehydrated, irritated, congested, calm. It moves with the weather, with sleep, with what you have been putting on it, with whether you have been travelling.
Most people shop for their type and suffer from their condition. Someone with genuinely oily skin can be badly dehydrated at the same time — the two are unrelated, and the routine that helps is not the one on the oily-skin shelf.
Four questions worth answering before you buy anything
None of these needs a device, an app, or a photograph. They need about a week of paying attention.
1. How does your face feel ten minutes after cleansing, with nothing on it?
Tight, squeaky or stinging means the cleanser is doing too much, whatever your type. Comfortable means it is doing its job. This single question resolves more complaints than any serum.
2. Where is the shine, and when does it arrive?
All over by mid-morning reads differently from a nose and forehead by evening. The second is extremely common and rarely a problem to solve.
3. Does anything sting, and does it sting every time?
Stinging that happens with one product is that product. Stinging that happens with almost everything, including water, is a skin that is currently reactive — and a reactive skin needs fewer products, not a better one.
4. What changed in the last month?
A new product, a new climate, a new season, a course of something. Skin lags behind its causes by two to three weeks, which is long enough that almost nobody makes the connection unaided.
"Sensitive skin" is usually a state, not an identity
People adopt sensitive as a permanent label and then buy sensitive-skin products forever. Sometimes that is right — some skin is reactive as a baseline trait, and it stays that way.
Often it is not. Skin becomes temporarily reactive after over-exfoliating, after too many actives at once, after a strong cleanser, after a winter. It settles, given a short routine and a few weeks. The label outlives the state, and the buying pattern outlives both.
Worth saying plainly: if your skin stings persistently, cracks, bleeds, or has changed in a way that worries you, that is a question for a doctor or a dermatologist and not for a shop. We would rather say that than sell you something.
Then, and only then, read the label
Once you can describe what your skin is actually doing in one sentence, an ingredient list becomes useful. Before that it is decoration — you are matching words on a box to words in a video, and neither has met your face.
Two habits that survive contact with reality:
- Change one thing at a time. Two new products at once and you have learned nothing about either.
- Give it four weeks before judging. Anything that promises a visible difference in three days is describing hydration, which is real, temporary, and not the thing you were hoping for.
If you want a second opinion
We built a tool for exactly this reading: Read my skin. It asks about condition rather than type, it gives you an honest account of what is probably going on, and it deliberately does not hand you a shopping list at the end. Sometimes it suggests one product. Often it suggests none.
If you already know what your skin is doing and want the routine rather than the reading, Build my routine is the other door. It is the same catalogue and a different question.
Either way, the order matters. Read first, then buy — and be prepared for the reading to tell you that the answer is to remove something rather than add it.
