Does moisturizer go before or after sunscreen?

Moisturizer goes first. Sunscreen is the last skincare step in the morning, before makeup.

Can I use retinol and vitamin C together?

Many people use vitamin C in the morning and retinol at night, which avoids irritation from stacking them.

Should I wait between skincare steps?

There’s no strong evidence for long waits. Let each layer absorb for a moment so the next spreads evenly, especially sunscreen.

01 · The short version

Most layering advice boils down to one idea: thinnest to thickest, and sunscreen last in the morning. Everything else is a detail.

Here’s a simple order you can follow, and the handful of combinations worth spacing out.

02 · Morning order

The morning goal is to protect: clean skin, optional antioxidant, moisturizer, then sunscreen as the final step.

1. Cleanse (or just rinse with water if your skin is dry).
2. Treatment serum, e.g. vitamin C or niacinamide.
3. Moisturizer.
4. Sunscreen, generously, as the last skincare step.

03 · Night order

Night is for treatment and repair. Put your main active on clean skin, then moisturize.

1. Cleanse (double-cleanse only if you wore heavy sunscreen or makeup).
2. Main active: a retinoid or an exfoliating acid, not both on the same night at first.
3. Moisturizer.
4. Optional: an occlusive like petrolatum on very dry areas.

04 · Combinations worth spacing out

Most “never mix” rules are overstated. A few are worth respecting, mostly to avoid irritation.

Retinoids and strong acids (AHA/BHA): alternate nights while you’re adjusting.
Benzoyl peroxide and tretinoin: BPO can break down some tretinoin; use at different times unless the product is designed to combine them.
Vitamin C and niacinamide: generally fine together despite old warnings.

05 · The science

Water-based serums spread best on bare skin; heavier creams and oils slow water loss and go on top. Sunscreen needs to form an even film, which is why it goes last.

Irritation, not the order itself, is the main thing that derails routines. Introduce one new active at a time, about two weeks apart.

The Receipt

01Thin to thick; sunscreen last in the morning.
02One main active per night while you’re learning your skin.
03Consistency beats perfect layering.

Education, not a diagnosis. If something changes quickly, hurts, bleeds, or worries you, see a dermatologist.
