How to Layer Serums and Oils: What Goes First?

Knowing whether to reach for serum or oil first is one of those small questions that can make a routine feel either effortless or unexpectedly confusing. This guide brings together facialist-led thinking on skincare layering order, including where our Brilliance Facial Oil fits, how to pair textures for your skin's needs, and how a morning and evening routine can each feel calm and considered without becoming complicated.

Serum or oil first? The simple layering rule to follow

If you've ever stood at your bathroom shelf wondering whether serum or oil goes on first, you're not alone. It's one of the most common skincare questions, and the answer is more straightforward than most guides make it sound.

As a general rule, serum goes on before oil. The reason comes down to texture and how each formula is designed to work. Serums are typically lightweight and water-based, built to deliver actives efficiently into the skin. Oils are richer and more occlusive — they condition the skin and help retain what's been applied beneath them. Used in that order, each product has the space to do what it does best.

This follows broader skincare guidance, too. Applying oil first can create a surface that lighter serums struggle to penetrate, which means their active ingredients may not absorb as effectively.

For best results, keep lighter treatment steps close to the skin before richer textures follow: serum first, moisturiser next, then facial oil. If your skin wants extra comfort, you can also mix a few drops of facial oil into your moisturiser rather than adding another layer. 

Throughout this guide, you'll find a clear step-by-step approach to skincare layering, guidance on where our Brilliance Facial Oil fits within a routine, and advice on reading your skin so that mornings and evenings feel equally effortless. If you'd like to revisit the fundamentals first, our full skincare application order guide is a helpful place to start.

How to layer your skincare step by step

A well-layered routine needn’t feel complicated. If you’ve been wondering whether to apply serum or oil first, a simple order helps everything sit more comfortably on the skin and keeps the ritual feeling calm rather than crowded.

1. Cleanse with Moringa Cleansing Balm. Warm a little balm between your fingertips and massage it over dry skin in linear strokes, not circles. It melts from balm to oil, then into a soft milky texture with water, helping to lift makeup, SPF and daily build-up while keeping skin feeling soft and comfortable.
2. Remove with the Dual Action Cleansing Cloth. Dampen the cloth, then begin with the microfibreside to gently sweep away the balm. Turn to the cotton muslin side to gently polish the skin. It’s a small detail, but it makes cleansing feel thorough and beautifully unhurried.
3. Add a prep step, if you like one. A hydrating mist or gentle toner can help skin feel fresh and ready for what follows. This step is optional, but it can make the rest of your skincare layering order feel even smoother.
4. Apply your serum. This is the point where the serum before oil rule comes in. Serums are usually lighter in texture and designed to be applied onto freshly cleansed skin, so they can sit close to the skin before richer layers follow. Press a few drops over the face and neck, then give it a moment to settle in.
5. Follow with moisturiser. After serum, smooth on your moisturiser to add hydration and day-to-day comfort. For many routines, this is the step that helps bring everything together, especially if your skin enjoys a cream texture before oil.
6. Finish with facial oil, if it suits your skin. If you enjoy using an oil, it usually sits best as the final layer, pressed over moisturiser. That includes evenings when you want a little extra nourishment, or mornings when skin is feeling drier and you prefer a more cushioned finish. If your routine is very simple, some people may choose serum and oil without a moisturiser, but where all three are used, serum first, moisturiser next and oil last keeps the order clear.

Where Brilliance Facial Oil fits in your routine

Brilliance Facial Oil is the step to reach for when skin wants more softness, nourishment and glow. Its blend of botanical oils helps skin feel supple and comforted, while the silky texture gives enough slip for slow facial massage across the face, neck and décolleté.

In a full routine, the order is simple: serum first, moisturiser next, facial oil last. This lets your lighter treatment steps sit close to the skin before the oil adds a final layer of comfort.

You can also mix a few drops into your moisturiser if your skin wants extra nourishment without adding another separate step.

Brilliance Facial Oil can then be used in different ways throughout your ritual: 

• Press over moisturiser at night when skin feels dry or depleted.
• Mix into moisturiser for extra comfort and softness.
• Use for facial massage when you want more slip across the face, neck and décolleté.
• Blend one drop into foundation for a softer, more radiant-looking finish.
• Tap onto high points when skin needs a little glow.
• Smooth over cuticles or dry patches as a targeted nourishing step.

If you would like a little more guidance on textures, timing and how to adapt oil to your own routine, our guide to adding facial oil to your skincare routine takes you through it step by step.

Choosing the right serum-and-oil combination for your skin

Not every skin needs the same combination, and that is part of what makes layering so personal. What your skin is asking for today might be different from yesterday — deep hydration after a long day, a radiance boost before a big morning, or something softer and more comforting when it feels a little reactive. Getting that pairing right matters just as much as understanding the order you apply things in.

Here is a simple guide to help you match your routine to what your skin needs most:

• Deep hydration: A hyaluronic acid-based serum draws moisture in beautifully, followed by a nourishing facial oil to help hold it there. Drier skin types tend to do well with a richer oil.
• Radiance and glow: A brightening serum pairs well with a lighter, fast-absorbing oil that sits comfortably on the skin without feeling heavy.
• Texture refinement: A smoothing or resurfacing serum followed by a mid-weight oil gives skin both the active support and the softness it needs.
• Extra comfort and resilience: A calming, hydration-focused serum layered beneath a richer oil offers a soft, protective finish — particularly welcome in cooler months or on days when skin feels more sensitive.
• Combination or oilier skin: A lightweight serum with a finer-textured oil keeps things balanced, without adding unnecessary weight.

Applying serum before oil — working from lighter to richer textures — is what keeps the routine feeling effortless. Each layer has room to absorb properly, so there is no pilling, no heaviness, and no sense of overload. Our serums and oils are curated with this kind of thoughtful pairing in mind, so it is a good place to start if you are building or refining your routine.

Above all, a well-chosen routine should feel like something you look forward to: calm, sensorial and considered, rather than a list of steps to get through.

Morning vs evening: when to use vitamin C, serum and oil

Your routine can feel a little different in the morning and evening, even though the layering order stays reassuringly simple.

In the morning, the Emma Hardie approach is to begin with the Vit C Brightening Cleansing Balm. Sweep it away with the Dual Action Cleansing Cloth, using the microfibre side first to lift away balm, then the muslin side for a softly polished finish. From there, a vitamin C serum is often the natural next step. If you are exploring our serums and oils, the Vit C Brilliance Renewal Serumsits beautifully here, supporting radiance before moisturiser and SPF. If your skin enjoys a little extra nourishment by day, a few drops of oil can be pressed on after serum and before moisturiser or SPF, keeping the texture light.

Evening tends to be a little more cocooning. Start with Moringa Cleansing Balm to melt away makeup, SPF and the day’s build-up, again removing with the Dual Action Cleansing Cloth: microfibre side first, muslin side second. If your skin likes a second cleanse, Moringa Light Cleansing Gel can follow as an optional extra or as a lighter alternative on other days. Then apply your chosen treatment serum, and finish with face oil to add comfort and seal in the layers beneath.

So if you are still wondering about serum or oil first, the answer stays the same: serum before oil. What changes with the time of day is where vitamin C fits best, and whether oil plays a light supporting role in the morning or a richer one in the evening.

How to build a routine that feels consistent and easy to keep up

The most effective routine is rarely the most complicated one. Once you understand the basic principle of layering lightest to richest, everything else tends to fall into place — and from there, small adjustments based on how your skin feels each day will come naturally.

If you are just starting out, cleansing is the best place to begin. A thorough, comfortable cleanse prepares the skin to absorb everything that follows, and once that foundation is in place, you can build gradually: a serum, then an oil, then a moisturiser, rather than introducing everything at once and trying to work out what is doing what.

The same thinking applies when moving between morning and evening. You do not need two entirely separate rituals. Often it is the smaller shifts that make the difference — reaching for your Vitamin C serum in the morning, or adding Brilliance Facial Oil in the evening when your skin wants a little more nourishment.

As for whether serum or oil comes first, there is no single answer that suits every skin type. The guidance here gives you a clear and considered starting point, but your routine should ultimately feel comfortable and easy to return to each day. Consistency, more than anything else, is what makes a routine work.

Frequently Asked Questions

What goes on first, oil or serum?

Serum goes on first, then oil. Serums are usually lighter and designed to sit close to freshly cleansed skin, while oils are richer and help lock in the layers underneath. In a full routine, it often goes cleanser, serum, moisturiser, then facial oil as the finishing step.

Can I apply oil after serum?

Yes, oil is usually best applied after serum. That order lets the lighter serum absorb first, while the oil sits on top to add comfort and help seal in what has already been applied. If you are using moisturiser too, oil generally comes last.
