The general rule for layering skincare is thinnest to thickest consistency, which usually (though not always) lines up with the order products should go on. Getting this wrong doesn’t just waste product — a heavier layer applied too early can block a thinner, more active-rich product from penetrating properly.
A typical order:
- Cleanser — always first, to start with a clean base.
- Toner (if used) — thin, water-based, preps skin for what follows.
- Serums, in order of thinnest to thickest texture — typically water-based active serums (like a vitamin C or niacinamide serum) before thicker, oil-based ones.
- Spot treatments — targeted actives applied precisely where needed.
- Moisturizer — seals in everything applied before it.
- Sunscreen (morning only) — always the last skincare step before makeup, since it needs to sit on top to form an effective, even film rather than being diluted or broken up by products layered over it.
A few specific rules worth remembering: Water-based products generally go before oil-based ones, since oil can create a barrier that prevents water-based actives from absorbing properly. Sunscreen should always go last in a morning routine — applying moisturizer or makeup over it doesn’t just risk diluting it, it can genuinely reduce how evenly and effectively it forms a protective film. And when introducing multiple new actives, waiting a few minutes between layers (rather than piling everything on at once) gives each product a better chance to absorb rather than sitting on the surface and potentially pilling.
None of this needs to be exact to the minute — the underlying logic (thin before thick, water before oil, sunscreen last) is more useful to internalise than a rigid step-by-step you have to look up every morning.
