Skincare routine order builder

Thin to thick is only half the rule. Order genuinely matters in three places: sunscreen goes last in the morning, anything that depends on a low pH goes on clean skin, and occlusive balms go last at night because nothing gets through them. Between those three, the order you will actually keep matters more than the perfect one.

Tick what you use above and the builder sorts it into a morning and an evening routine. It also flags combinations that are better on different days, and it tells you when something in your evening routine makes morning sunscreen non-negotiable.

What order to apply skincare in the morning

1. Cleanser, or just water if your skin runs dry
2. Toner, essence or hypochlorous acid spray, if you use one
3. Vitamin C serum, on clean skin
4. Other serums, from thinnest to thickest
5. Eye cream
6. Moisturiser
7. Sunscreen, last and on its own

What order to apply skincare at night

1. Oil or balm cleanser, if you wore sunscreen or makeup
2. Water-based cleanser
3. Exfoliating acid or retinoid on clean, dry skin, but not both on the same night
4. Treatment and hydrating serums
5. Eye cream
6. Moisturiser
7. Face oil, then any occlusive balm

The three places where order really matters

The first is sunscreen. It is tested as a continuous film at 2 milligrams per square centimetre, and that is the only condition under which the number on the bottle means anything. Mixing it into moisturiser, or working another product through it, thins the film. It goes on last, by itself, and in more quantity than most people use.

The second is anything that depends on a low pH. Pure vitamin C and exfoliating acids only work while they stay acidic, so they go on clean skin and get a short moment to absorb before the next layer. You are not avoiding a dangerous reaction. You are avoiding buffering an active you paid for into doing nothing.

The third is occlusives. A balm or ointment works by sitting on top and slowing water loss, and it does not distinguish between water leaving and your next product arriving. That is the real basis for "thin to thick", and it applies to genuinely occlusive products rather than to every cream. I went through all three at more length in does the order of your routine actually matter.

Where does retinol go in a routine?

In the evening, after cleansing and before moisturiser. Retinol breaks down in light, which is why it belongs to the night. If it makes your skin sting or flake in the first weeks, the usual adjustment is to put a light moisturiser on first and the retinol over it, which slows how quickly it reaches the skin.

Do you need to wait between steps?

Not for twenty minutes, whatever the charts say. A short pause, long enough that the previous layer is no longer visibly wet, is the part with a rationale behind it. With a humectant such as hyaluronic acid, the step that matters more is putting something over it rather than waiting.

If you are unsure whether two of your products belong together at all, the ingredient combination checker answers that for any pair.

Frequently asked

Do you put moisturizer before or after sunscreen?

Before. Sunscreen is tested as a continuous film at 2 milligrams per square centimetre, so it goes on last and on its own. Mixing it into moisturizer, or massaging another product over the top, thins that film. If your skin needs moisturizer, apply it first and give it a minute to settle before the sunscreen.

When do you apply retinol in your routine?

In the evening, on clean, dry skin, after cleansing and before moisturizer. Retinol breaks down in light, which is why it belongs to the night routine. If it stings, apply a light moisturizer first and the retinol over it. Keep exfoliating acids for a different evening.

Does the order of skincare really matter?

In three places, yes: sunscreen last in the morning, low-pH products such as vitamin C on clean skin, and occlusive balms at the very end. Between those, for example essence before or after serum, there is little evidence that the order changes anything you would notice. A routine you keep matters more.
