A routine is a sequence, not a collection. Applied in the wrong order, two good products can cancel each other out — a rich cream before a serum physically blocks it from reaching the skin, and an occlusive layer over a treatment slows the thing you wanted to happen.
The working rule is consistency of texture. Move from the thinnest, most fluid product to the thickest, most occlusive one, and let each layer settle for a moment before the next.
The order that holds up
- Cleanse — and double cleanse in the evening if you wore SPF or makeup.
- Tone, if your toner is a treatment step rather than a freshener.
- Serum or treatment — this is where actives live, on clean skin, closest to the surface.
- Moisturiser — to hold water in and support the barrier the actives just worked on.
- SPF in the morning, as the final step, every day.
Morning and evening are not mirror images. Evening is the better home for exfoliating or renewing products, because sun exposure and the rest of the day are no longer stacked against them. Morning is the better home for antioxidants and protection.
Where people usually go wrong
Two habits cause most of the trouble. The first is layering several actives at once and then treating the resulting irritation as a reason to add a soothing product — which is a third layer on a problem caused by the first two. The second is skipping moisturiser because a serum "already feels like enough". A serum is a treatment; it is not a barrier.
If you are rebuilding a routine, start with the boring parts — cleanse, moisturise, protect — and add one active at a time.
