How to Layer Skincare Products in the Right Order

The order you apply your skincare matters. The right sequence means every product reaches your skin as intended. The wrong one can reduce efficacy - or in some cases, cause unnecessary irritation. 

There's a logic to layering that, once you understand it, becomes second nature. It's not complicated. It's just not always explained clearly. 

Here's how it works - and why. 

The Core Principle: Thinnest to Thickest 

The most reliable rule for layering skincare is to apply products from the thinnest consistency to the thickest. This works because thinner, water-based formulas are absorbed quickly and penetrate deeper into skin; thicker, oil-based or occlusive products form a layer on top that would block thinner products from reaching skin if applied first. 

Think of it in terms of what you're trying to achieve: you want actives (the ingredients doing the targeted work) to reach skin, then seal these in with richer formulas over the top. For example, a serum is usually your hardest working and highest active content step, so always make sure you apply this before a moisturiser or SPF. 

There's a secondary principle: water-based products before oil-based products. Water and oil don't mix - an oil-based product applied first will prevent water-based serums from penetrating. 

Step by Step: The Full Layering Order 

1. Cleanser 

Everything starts with clean skin. A cleanser removes the day's buildup (or overnight sebum in the morning) so that nothing you apply afterwards is trying to penetrate through a layer of SPF, sebum, makeup, pollution or general residue from daily grime. 

2. Toner 

Toners applied at this stage serve to rebalance skin after cleansing, deliver a first layer of active ingredients, and prepare skin to absorb what follows. The key is choosing a toner that adds something meaningful, rather than simply adding a step. 

3. Serum 

This is the hardest working step of your routine - the stage where the active ingredients that address your specific concerns are applied. Serums are generally formulated with smaller molecules that penetrate deeper than moisturisers, delivering higher concentrations of actives where they're needed most. 

If you want to use more than one serum, apply them thinnest to thickest. 

Allow each serum to absorb for 30-60 seconds before the next. You don't need to wait until the skin is completely dry, just until the product is no longer visibly wet on the surface.  

4. Eye Cream 

Often a step people skip but one which we really advise you do twice daily! If you use an eye cream, apply it after serums and before your moisturiser. The under-eye area has thinner, more delicate skin - applying eye cream before moisturiser ensures it's not diluted or blocked by heavier formulas. 

5. Moisturiser 

Moisturiser's role in the layering sequence is to seal in the hydration and actives applied beneath it, while delivering its own skin boosting and supporting ingredients. Apply after your serum and eye cream.  

6. SPF (Morning Only) 

SPF is always the last step in your morning routine - applied after moisturiser. This is important: SPF needs to sit on the skin's surface to form its protective layer. Applying anything on top of SPF (other than makeup) reduces its efficacy. 

if you are using a product like our Glow-C Daily Moisturiser SPF30 then this is a moisturiser and SPF in one so is simply applied after your serum and eye cream as the final step before any makeup you choose to add. 

Whether you choose a standalone SPF fluid or a daily moisturiser like our Glow-C Daily Moisturiser SPF30 which includes SPF alongside hydration benefits is completely up to you – there’s no right or wrong, pick the product you like the texture of and works best with your routine. Just make sure you do it daily come rain or shine – it’s the most powerful preventative tool available to prevent further skin damage and boost skin’s natural longevity. 

7. Facial Oil (Evening only) 

In your evening routine, if your skin is particularly dry or in need of some SOS support, you can layer an oil over the top of your moisturiser for an additional hydration boost. Facial oils are occlusive - they seal everything beneath them in place, preventing overnight moisture loss.  

This step isn’t essential but one which you might benefit from depending on your skin type and condition. 

Common Layering Mistakes 

Applying SPF mid-routine. SPF goes last in the morning, always. Applying serums or moisturisers on top of SPF can break down the protective filter. 

Using too many serums at once. More actives does not mean better results. 1-2 well-chosen serums applied correctly will outperform six competing products applied in the wrong order or that conflict with one another or risk overloading your skin with too many actives which can damage your skin barrier. Keep your routine focused. 

Applying thick products before thin ones. A rich moisturiser applied before a water-based serum blocks the serum from reaching skin. The logic of thinnest-to-thickest exists for a reason.
