When a few products are added to a routine, the first question is usually which order to apply them in. The good news is that the order is not a long list to memorise. There is one simple principle behind it. Once you understand it, you can work out most situations yourself. Below, we explain that principle and a few common points of confusion: a measured framework, not rigid rules.
The Basic Principle: Thin to Thick
The general principle is: water-based, thin textures first; thicker, oily textures later. A typical order looks like this:
- Cleanser
- Toner or essence (the thinnest, watery layer)
- Serum (water-based actives)
- Eye-area care, if used
- Moisturiser (a thicker texture)
- Face oil, if used (on top, because it is oil-based)
- Morning: sun protection (always the final skincare step)
The reasoning is straightforward: thin, watery layers go underneath; thicker, oily layers go on top. The practical reason is that a water-based product becomes harder to apply over an oil-based texture, as oil tends to keep water on its surface. In other words, the order depends on the product's texture, not its name; consistency matters more than whether the label says serum or moisturiser.
Morning and Evening Are Different
Although the basic order remains the same, morning and evening routines have different aims. A practical framework:
- The morning routine focuses on protection: cleansing, an antioxidant if used (such as vitamin C), moisturising and sun protection as the final step.
- The evening routine focuses on renewal and repair: cleansing, actives associated with renewal (such as retinol) or exfoliating acids if used, followed by barrier-supporting hydration.
Exfoliating acids and retinoids can make a routine more sensitive to light, so they are usually considered evening options. Antioxidants are more suited to the morning as a supportive layer against daytime exposure. This is a measured preference, not a prohibition.
Are Waiting Times Really Necessary?
Another common claim is that you need to wait a long time before applying each layer. In most routines, this is not necessary; applying layers one after another generally causes no problem. There are a few exceptions: a short pause after a low-pH active (pure ascorbic acid or certain exfoliating acids) may feel more comfortable on some skin. Even then, it is not a requirement but a matter of tolerance and feel. As long as your skin is comfortable, you do not have to count the minutes.
A Few Common Points of Confusion
Essence or serum first? Essences generally go before serums because they are thinner; again, consistency is the deciding factor. Where does face oil fit? Because it is oil-based, it is usually placed after moisturiser, as the top skincare layer. What about sun protection? It is always the final step of the morning routine. It is not an additional step on top of a serum or active, but what completes daytime care. Thinking of all this as the logic of texture, rather than strict rules, helps the routine fall into place.
