In what order do you apply skincare?
Short version: cleanser, then any watery step such as a toner or essence, then serum, then the treatment of the day, then moisturiser, and in the morning sunscreen last. Two rules generate the whole sequence: thin before thick, and water before oil.
The two positions that genuinely matter are the first and the last. Cleanser first, sunscreen last in the morning. Everything in between changes how well each layer spreads, which is a real effect and a smaller one than the internet suggests.
Almost every routine question people ask an assistant is really this question wearing a costume. Where does the serum go, does sunscreen go over moisturiser, can the retinol go on before the cream. They all fall out of one sequence, so here is the sequence, and then the reasoning underneath it, so you can slot in any product you buy later without asking again.
What is the correct order to apply skincare?
| Step | Morning | Evening |
|---|---|---|
| 1 · Remove | not needed | Oil-based cleanser, over dry skin, to take off sunscreen and makeup |
| 2 · Cleanse | Gentle cleanser, or plain water if your skin prefers it | Gentle cleanser |
| 3 · Watery step | Toner or essence, optional | Toner or essence, optional |
| 4 · Serum | Vitamin C, or another thin watery serum | Hydrating serum, optional |
| 5 · Treatment | rarely, and never a retinoid | Retinoid, acid or benzoyl peroxide. One per night |
| 6 · Eyes | Eye product, optional | Eye product, optional |
| 7 · Moisturise | Moisturiser | Moisturiser, richer if the skin wants it |
| 8 · Protect | Sunscreen. Always last | none |
If your bathroom shelf holds three products rather than eight, the sequence collapses to cleanser, moisturiser, sunscreen, and that is a complete routine rather than a starter one.
Why does the order matter at all?
Two mechanical reasons, and they are worth understanding once because they let you place any future product yourself.
The first is penetration by texture. A watery serum applied to bare skin has nothing in its way. The same serum applied over a rich cream has to get through a layer built to sit on the surface and slow water loss, and much of it simply will not. Thin before thick is not aesthetics, it is the order in which the layers can still reach the skin.
The second is what the last layer is for. Sunscreen works as a continuous film on top of everything. Anything you rub over it thins and breaks that film. That is the whole reason sunscreen is last rather than somewhere in the middle where its texture might suit you better.
The part nobody says out loud: for the middle of the routine, order is a small effect. Whether your hydrating serum goes before or after your niacinamide will not decide anything. Being consistent for eight weeks will. Most routines that are not working are not badly ordered, they are badly kept.
What is the morning order, step by step?
Overnight your skin collected sebum and whatever was on the pillow. A gentle cleanser handles it. If mornings leave your skin feeling tight, plain water is a legitimate answer rather than a shortcut.
A watery layer on slightly damp skin. It makes everything after it spread more easily. Fully optional.
Morning is where vitamin C usually lives, mostly because the evening is already crowded. See the vitamin C page for the difference between pure ascorbic acid and the gentler esters.
Order here is a preference, not a rule. Before moisturiser is the common choice because it is the thinner of the two.
Over everything water-based. This is also the step that makes the sunscreen above it spread evenly instead of dragging.
Nothing skincare goes on top. Makeup can, sunscreen cannot be sandwiched. More on quantity and reapplication on the SPF page.
What is the evening order, step by step?
Sunscreen is built to resist water, so water alone does not lift it. An oil-based cleanser or a balm, worked over dry skin and then emulsified, is what takes it off. This is the single most skipped step in most routines.
A short second pass on a surface that is already clear. Two mild cleanses beat one aggressive one.
Toner or essence, same as the morning.
One active, not three. A retinoid, an exfoliating acid, or benzoyl peroxide, on skin that is dry to the touch. Which combinations clash and which are fine is a page of its own.
Last step of the evening. If the treatment step feels sharp, applying moisturiser first and the active on top of it is a legitimate way to soften the start.
Where does sunscreen go, and does anything go on top?
Sunscreen is the last skincare step of the morning, over moisturiser, under makeup. Two follow-ups that come up constantly:
- Mixing sunscreen into moisturiser spreads it thinner than the label assumes. Apply them as two layers.
- Reapplying over makeup is where sticks, powders and mists earn their place. They are a maintenance layer, not the first application.
Where do retinol, acids and vitamin C go?
Vitamin C in the morning, retinoids and acids at night. This split is not chemistry folklore, it is scheduling: the evening slot holds one strong active comfortably and three uncomfortably, so the mildest of the three moves to the morning. Vitamin C is the one that moves most easily, and pairs naturally with the sunscreen step that follows it.
Within the evening, the treatment slot is singular on purpose. Two exfoliating steps stacked on one night is the most common way a routine turns from pleasant into stinging, and the fix is a calendar rather than a better product. Alternate nights, not layers.
How long should you wait between layers?
Until the previous layer is no longer wet. In practice that is fifteen to sixty seconds, and you can feel it. The famous "wait thirty minutes" rule comes from one narrow case, pure L-ascorbic acid at a low pH, and got generalised into advice that makes routines so slow people abandon them. A routine you do every night at a normal pace beats a perfectly timed one you do twice a week.
What order does Baselit put your routine in?
This is the part our app is actually built around, so here is what it does, plainly.
- Fixed AM and PM slots. Every recommended step carries its own layer position and its own time of day, so the routine comes out already sequenced rather than as a shopping list you have to arrange yourself.
- A reason on every step. Each step says why that product, why in that position, and why morning or evening. That is the part most routine builders leave out, and it is the part that lets you keep the routine when you swap a product later.
- One strong active to start. Beginners get a maximum of one irritating active plus gentle supports. A second one is held back until the first is settled, which is the same advice as the "one treatment per night" rule above, enforced rather than suggested.
- A clash check on products. The engine will not put a product in your routine whose secondary active collides with something already in it, and you can send a photo of a product you already own to Mia, our in-app coach, to hear whether it fits the routine and which slot it belongs in.
The routine is built from a selfie scan that reads five areas of visible skin appearance, and it updates when the scan does. What the score is and is not is covered in how skin scores work.
