Your routine

Morning

  1. CleanserStart on clean skin. The AAD suggests washing your face twice a day, when you get up and before bed. (AAD: Skin care in your 20s)
  2. Vitamin C serumA thin serum straight after cleansing (or toner), usually in the morning, under moisturiser and sunscreen. (Cleveland Clinic: Skin care routine order)
  3. Hyaluronic acid or hydrating serumWatery serums can go before or after a treatment serum; a common habit is treatment first, then hydration. (Cleveland Clinic: Skin care routine order)
  4. MoisturiserThe thickest everyday layer goes on after thinner ones. (Cleveland Clinic: Skin care routine order)
  5. SunscreenAlways the last skincare step in the morning, after other products and under makeup. (AAD: Skin care in your 20s)Apply about 15 minutes before going outdoors; reapply about every two hours when outside, or after swimming or sweating. (AAD: Sunscreen FAQs)

Evening A

Alternate between evenings A and B.

  1. CleanserStart on clean skin. The AAD suggests washing your face twice a day, when you get up and before bed. (AAD: Skin care in your 20s)
  2. AHA exfoliant (glycolic, lactic, mandelic)Exfoliating acids go on clean, dry skin before thicker layers. AHAs raise UV sensitivity, so use sunscreen the next morning. (FDA: Alpha hydroxy acids)
  3. Hyaluronic acid or hydrating serumWatery serums can go before or after a treatment serum; a common habit is treatment first, then hydration. (Cleveland Clinic: Skin care routine order)
  4. MoisturiserThe thickest everyday layer goes on after thinner ones. (Cleveland Clinic: Skin care routine order)

Evening B

  1. CleanserStart on clean skin. The AAD suggests washing your face twice a day, when you get up and before bed. (AAD: Skin care in your 20s)
  2. Hyaluronic acid or hydrating serumWatery serums can go before or after a treatment serum; a common habit is treatment first, then hydration. (Cleveland Clinic: Skin care routine order)
  3. Retinol or retinalEvening only: the AAD advises using retinoids at night because they make skin more sensitive to the sun. Start every other night. (AAD: Retinoid or retinol?)
  4. MoisturiserThe thickest everyday layer goes on after thinner ones. (Cleveland Clinic: Skin care routine order)

Pairing notes

  • AlternateAHA exfoliant (glycolic, lactic, mandelic) + Retinol or retinalPut on different evenings.The AAD warns that exfoliating while using retinol or a retinoid can worsen dryness or even trigger breakouts. Use them on different nights, and skip the acid while your skin is red or flaky. (AAD: How to safely exfoliate at home)

How the order is worked out

Thinnest to thickest. Cleveland Clinic's rule of thumb is to layer from the lightest, most watery product to the heaviest: cleanser, toner or essence, serums, eye cream, then moisturiser. Thin layers go on first so a cream doesn't block them. Face oil sits just before moisturiser in Cleveland Clinic's order; some people prefer it last at night.

Sunscreen last in the morning. The AAD says to put sunscreen on after your other skincare and under makeup, about 15 minutes before you go out, and to reapply about every two hours outdoors.

Retinoids at night. Retinol, adapalene and tretinoin make skin more sensitive to the sun, so the AAD advises using them in the evening. Tick Put my retinoid after moisturiser to apply moisturiser first, one of the ways a dermatologist may suggest to reduce irritation.

Clashing actives. Each pair of actives is checked against the pairing checker's matrix. When two evening products are better used on different nights (retinol and a glycolic acid toner, say), you get Evening A and Evening B to alternate. Morning clashes are listed for you to move. Pairs involving a prescription retinoid are marked ask a clinician.

Example. The default picks (cleanser, vitamin C, hyaluronic acid serum, retinol, an AHA, moisturiser and sunscreen) give one morning routine and two evenings: retinol on one, the AHA on the other, both followed by serum and moisturiser.

Choose Both, Morning or Evening beside each product. Print it for the bathroom mirror, or copy it as text.

Questions

What is the right order to apply skincare?

From the thinnest product to the thickest: cleanser, toner or essence, serums and treatments, eye cream, then moisturiser. In the morning, sunscreen goes on last, after your other skincare and before makeup. If a product comes with its own directions, or a prescriber has told you otherwise, follow those.

Do I need to wait between layers?

None of the sources we use gives a fixed waiting time between skincare layers, so the builder doesn't invent one. Letting a layer sink in or dry before the next is a sensible habit. The one timing that is sourced: the AAD advises applying sunscreen about 15 minutes before going outdoors.

Why does my evening split into Evening A and Evening B?

Two of your evening actives are better on different nights, usually a retinoid and an exfoliating acid, which the AAD says can worsen dryness when combined. Alternate between the two evenings; everything that doesn't clash, like cleanser, serum and moisturiser, appears in both.

Can vitamin C and niacinamide go in the same routine?

Yes. The worry comes from old lab chemistry on the pure substances, not from skin studies. Clinical trials have used formulas containing both, and niacinamide does not cause flushing. The pairing checker shows the details and sources.

I'm pregnant. Does the order change?

The order doesn't, but what you use might. The AAD says retinoids should not be used during pregnancy, so talk to a doctor, midwife or pharmacist before using retinol, adapalene or tretinoin if you are pregnant, trying to conceive or breastfeeding. Tick the pregnancy option and the builder flags any retinoid you picked.
