Always patch test before use: apply a small amount to the inner wrist or elbow, wait 24 hours.
If you are pregnant, breastfeeding, or have health conditions, seek medical advice before use.
Avoid contact with eyes and children.
Store finished oil in a cool, dark place away from sunlight.
Shelf life: 6–12 months when stored properly.
Use only dried petals — fresh petals contain water and may spoil the oil.

✨ Recipe
For 100 ml Golden Oil
10 g Calendula Petals
100 ml Sweet Almond Oil
1 g Vitamin E Oil
🧂 Method
1. Clean & Sterilise
Wipe jar, funnel, and spoon with alcohol. Let dry.
2. Combine Botanicals & Oil
Add calendula to your infusion jar.
Pour oil over until petals are submerged.
Gently stir to remove air pockets.
Keep your empty pump bottle aside (place the lid back on the bottle) — this is where you’ll store your finished infusion later.
⚠️ Important: Do not wash this bottle. Introducing water into the bottle or pump mechanism can lead to bacterial growth. Simply place the lid / pump back on.
3. Infuse Label, Store
Label the Jar with the Infusion Date, Herb & Oil used. Then seal the jar and store in a cool, dark place. Like a cupboard (with no sunlight).
Gently swirl every 3-4 days.
Infuse for 3 weeks.
4. Strain
Clean and sterilise a pouring beaker.
Place the muslin cloth over the top of the beaker (or secure with a band).
Slowly pour the infused oil through the cloth to catch petals and particles.
Gather the petals inside the cloth and gently squeeze to extract the remaining oil.
5. Preserve & Bottle
Add vitamin E oil and stir gently.
Transfer to the original bottle that your oil came in, seal with your pump.
⚠️ Important:You should not have washed this bottle. Introducing water into the bottle or pump mechanism can lead to bacterial growth. Simply place the lid / pump back on.
Handwrite on the original label the: Herb Name and Extraction Date.
✨ Usage
Daily moisturiser: Apply to face or body, absorbs beautifully.
Massage oil: Silky and lightweight, perfect for relaxation.
Makeup remover: Gently dissolves makeup while conditioning skin.
DIY base: Use in balms, creams, or other skincare creations.
💡 Tips & Troubleshooting
Cloudy oil? Strain again or allow longer settling.
Light golden colour? This is normal — calendula produces a subtle golden hue, not bright orange.
Skin sensitivity? Discontinue use if irritation occurs.
If you’ve ever looked into skincare, you’ve probably heard the words “skin barrier.”
But what actually is it?
Let’s make it really simple.
What is your skin barrier?
Your skin has an outer layer that acts a bit like a protective wall.
This is what people are talking about when they refer to the skin barrier.
One of its important jobs is helping keep water in your skin, while also helping protect you from the outside world.
You don't need to understand all the science behind it to look after your skin.
The important thing to remember is:
Your skin needs water, and it needs help holding onto it.
Why does our skin lose water?
Water naturally moves from our bodies, through our skin and into the air around us.
This happens to everyone, all the time.
When your skin barrier isn't working as effectively, more water can escape, which can contribute to dry or dehydrated skin.
This is where moisturising ingredients come in.
And there are three simple words worth knowing: 💧 Humectants, 🌿 Emollients & 🛡️ Occlusives.
💧 Humectants = help with water
Humectants help attract and hold onto water in the outer layer of your skin.
A common example is Glycerine.
Think: Humectant → Water
🌿 Emollients = make skin feel softer
Emollients help soften and smooth your skin.
Many carrier oils can act as emollients, including Jojoba Oil.
Think: Emollient → Soft & smooth
🛡️ Occlusives = help stop water escaping
Occlusive ingredients create a layer over your skin that helps slow down water loss.
Beeswax is a great example of an occlusive, while Shea Butter can help soften the skin and slow down water loss too.
Think: Occlusive → Helps keep water in
These groups can overlap, so an ingredient or skincare product doesn't always fit neatly into just one box.
But as a simple starting point, that's really all you need to know.
Here's a real example
Last week, Amy shared one of her favourite simple skincare routines with our email subscribers.
After washing her face, while her skin is still damp, she applies a small amount of Glycerine, followed by a few drops of Jojoba Oil.
Why?
Now you know!
The Glycerine is a humectant, so it helps with water in the outer layer of her skin.
The Jojoba is an emollient, so it helps soften and smooth her skin.
Amy likes applying her Glycerine to damp skin as part of her routine - but that's her preference, not a rule that everyone needs to follow.
That's the skin barrier in a nutshell
If you remember nothing else from this article, remember:
💧 Humectants → help with water
🌿 Emollients → soften and smooth
🛡️ Occlusives → help slow water loss
And your skin barrier is the protective outer layer helping to keep that water from escaping too quickly.
That's it.
Skincare doesn't always have to be complicated.

You've got a few essential oils sitting on your bench, or you're about to invest in some and want to get it right from the start.
And one of the first questions that comes up is almost always this:
Should I use a single essential oil in my products, or should I blend a few together?
Honestly? There's no single right answer. It depends on what you're making, who you're making it for, and what result you're after.
What we've done here is lay out the difference between the two approaches, when each one makes sense, and what to keep in mind as you work.
Whether you're making candles, body oils, bath products, or your first skincare formula, this will give you a clear foundation to work from.
First, a Quick Note on What Essential Oils Actually Are
Essential oils are concentrated aromatic extracts from plants, think the scent in a freshly peeled orange rind, or the smell that rises from a rosemary sprig when you crush it between your fingers.
They're complex materials. A single oil can contain dozens of chemical compounds, each contributing something different to the scent and how the oil behaves in a formula.
When you use one oil on its own, you're working with all of that in one bottle.
When you blend two or three together, those compounds start to interact. And that interaction is where things get genuinely interesting.
Start Here: Why Are You Using Essential Oils at All?
Before thinking about whether to use one oil or three, there's a more useful question to ask first.
Why are you using essential oils in this product?
There are two reasons people reach for essential oils, and knowing which one applies to your project will guide every decision that follows.
Reason 1 - Function: For their actions You want the oil to do something in the product. To bring conditioning, cleansing, or balancing properties to a formula.
To contribute to the experience beyond just the scent, a clarifying scalp treatment, a balancing body oil, a product that genuinely works with the skin rather than just sitting on top of it.
Reason 2 - Fragrance: For fragrance You want the oil for its aromatic character. The scent experience it creates in a candle, a room spray, a bath product, or any product where the smell is the primary point.
Both are completely valid. But they lead to different choices.
And here's the thing, sometimes one oil covers both completely. Lavender is the most obvious example. It has a well-rounded, widely loved aromatic character and well-established skin-conditioning properties.
For many simple products, lavender alone in a carrier oil is a finished formula. You don't need to add anything.
That's the case for a single oil. And it's a good place to start.
The Case for Using a Single Oil
There's a lot to be said for simplicity.
A single essential oil is clean and focused. You know exactly what's in your formula, how it will behave, and what to expect.
For beginners especially, starting with one oil is the smartest way to build genuine knowledge of your materials.
Single oils work best when:
- You're learning how an oil behaves in a particular base, how it performs in soy wax versus beeswax, or in jojoba versus a heavier carrier
- You want a clear, recognisable scent with nothing competing for attention
- You're formulating for sensitive skin, where fewer ingredients means fewer variables
- The oil you're using already covers both the fragrance and the properties your project needs
Not every project needs a blend. And if you're new to working with essential oils, spending time with one oil before layering in others is genuinely the better approach.
So When Does Blending Make Sense?
Blending makes sense when a single oil can't cover everything you need, whether that's a more complex scent, a longer-lasting aroma, or a formula that benefits from multiple oils working together on different aspects of the product.
Blending for Actions: Choosing Oils That Work Together
When you're choosing essential oils for their properties, blending becomes a deliberate, functional decision.
You're not just building a scent, you're building a formula where each oil has a specific job.
Example: a clarifying scalp oil Rosemary for its scalp-conditioning properties.
Tea tree for its cleansing action on the scalp surface. Cedarwood to help balance oiliness. Three oils, three different contributions, all working toward the same goal. None of them alone would cover all three.
Example: a calming body oil Lavender brings a soothing, conditioning quality to the skin. Roman chamomile deepens the calming aromatic effect. Frankincense adds a grounding, steadying dimension. Together they create a product experience that goes beyond what any single oil delivers.
Example: a brightening body scrub Sweet orange and grapefruit together create a vivid, uplifting aromatic character while both contribute skin-conditioning properties. A touch of peppermint adds a fresh, invigorating edge. Each oil has a reason to be there.
When blending for actions, ask yourself before adding any oil: what is this oil contributing to the formula? If you can't answer it, the oil probably isn't ready to be in the blend yet.
A note on safety: When using multiple oils for their properties, the total essential oil percentage across all oils is what matters, not each oil individually. Each oil has its own recommended concentration for safe skin contact, and those limits apply across the whole formula. Our guide to essential oil safety and dermal limits is a practical starting point if you're new to this.
Blending for Fragrance: Building a Scent That Lasts
When fragrance is your primary goal, in candles, room sprays, bath bombs, or any product where the aromatic experience is what you're designing, blending gives you something a single oil can't: depth, complexity, and longevity.
Essential oil compounds evaporate at different speeds. Light molecules, the ones responsible for that bright, vivid first impression, disappear quickly.
Heavier molecules linger. They stay on the skin, in the room, and in the product for hours.
When you blend a fast-evaporating oil with a slow-evaporating one, the heavier molecules physically slow down the evaporation of the lighter ones.
The bright top note you love lasts significantly longer than it ever would on its own.
This is the foundation of how top, middle, and base notes work in blending.
A useful starting ratio for most fragrance blends and leave-on products is roughly 20 to 30% top note, 40 to 60% middle, and 20 to 30% base.
We've covered the full science behind this in our complete guide to essential oil notes, worth reading alongside this one.
The Three Ways Oils Work Together
Whether you're blending for actions or for fragrance, the underlying chemistry works the same way.
When you combine essential oils, one of three things happens.
1. Additive effect Two oils doing a similar job simply add their contributions together. The result is more of the same effect, delivered more consistently.
Fragrance example: Lemon and grapefruit together produce a brighter, more vivid citrus opening than either one delivers on its own.
Action example: Lavender and Roman chamomile both bring a calming, soothing quality. Together, that calming character is more present and consistent across the life of the product.
2. Synergistic effect Two oils working through different mechanisms produce a result stronger than either would achieve alone.
Action example: Tea tree and eucalyptus in a cleansing product. Eucalyptus increases the permeability of bacterial cell membranes, which allows tea tree's active compounds to work more efficiently. The combined cleansing action is stronger than either oil delivers individually.
Fragrance example: Bergamot and frankincense. Bergamot brings a bright, uplifting top note. Frankincense brings depth and grounding. Together they create an aromatic experience, simultaneously energising and settling, that neither oil produces on its own.
3. Modulating effect One oil softens or balances the intensity of another, without reducing its effectiveness.
Fragrance example: Clove bud is a powerful oil with a sharp, intensely warm character. Alone, even at a low percentage, it can dominate a blend. Combined with sweet orange and cedarwood, it settles into a warm, spiced depth. The sweet orange lifts it, the cedarwood grounds it, and the clove becomes an asset rather than an overpowering presence.
Action example: Thyme CT thymol is a highly effective cleansing oil but assertive in character. Lavender blended alongside it rounds out the experience, not weakening the thyme, but making the overall formula more balanced and pleasant to use.
This third effect is particularly worth understanding if you've ever found an oil you love but found difficult to work with. Blending is often what unlocks it.
How to Build a Blend: A Beginner's Framework
You don't need to overthink this. Start with a simple structure.
Every blend works best with three layers:
A top note: the first impression, bright and vivid (citrus oils, peppermint, eucalyptus)
A middle note: the heart of the blend, the character that carries through (lavender, geranium, clary sage, ylang ylang)
A base note: the anchor, slow and enduring, keeps everything else present longer (cedarwood, sandalwood, frankincense, patchouli, vetiver)
Try This Blend First
Here's a simple body oil that demonstrates the layering effect clearly.
Calming Body Oil (2% total essential oil in carrier oil)
Oil
Role
Amount
Sweet orange
Top note - bright, fresh opening
0.5%
Lavender
Middle note - soft, floral character
0.8%
Frankincense
Base note - warm, woody depth
0.5%
Vetiver
Base note - earthy anchor
0.2%
Make this, then make a second version with sweet orange alone at 2% in the same carrier.
Apply both to your inner forearm. Come back an hour later and notice which one still has a scent. The difference in longevity is noticeable immediately.
A Note on Safety and Concentration
A facial leave-on product should generally stay within 0.5 to 1% total essential oil. A body leave-on sits around 1 to 2%. Five oils at 0.3% each adds up to 1.5%, which is fine for a body product but may be more than you want for a facial formula.
This is worth keeping in mind any time you're building a multi-oil blend for skin contact.
One More Thing: Heat and Your Blend
If you're making candles, balms, or any product that involves heat, there's one more thing worth knowing.
Different essential oils have different flash points, the temperature at which their aromatic compounds start to evaporate rapidly.
Add oils to a hot formula too early and you lose your top note character before the product even cools.
In a blend, this matters because top note oils are almost always the most heat-sensitive.
Getting the temperature right at the point of adding essential oils is one of the simplest ways to protect the work you've put into building a good blend.
Our guide to flash points covers exactly when and how to add essential oils to heat-based products.
The Practical Rule to Remember
Before any oil goes into a blend, ask yourself: what is this oil doing here?
If you can answer that, it's the top note, it's modulating the sharper oils, it's the anchor that keeps everything else present, then it belongs.
If you can't, it's worth waiting until you understand it better.
Start with two or three oils. Learn how they behave together. Add complexity gradually as your knowledge grows.
The most confident makers aren't the ones with the most oils. They're the ones who know their materials well enough to use them with intention.
Frequently Asked Questions
What's the difference between a single essential oil and a blend?
A single essential oil is one unblended oil, lavender, peppermint, frankincense, diluted in a carrier oil. A blend is a combination of two or more essential oils, chosen to complement each other in scent, performance, or both.
Should I use essential oils for fragrance or for their properties?
Both are valid reasons and often they overlap. Lavender, for example, brings both a well-loved aromatic character and skin-conditioning properties.
The key is being clear on your intention before you start blending. If you're using an oil for its properties, every oil in your formula should have a specific reason to be there. If you're blending for scent, you're building with top, middle, and base notes in mind.
Do blended essential oils really smell better than single oils?
Not always. Blends tend to be more complex and longer-lasting because different oils evaporate at different speeds.
But some of the most distinctive products are built around a single well-chosen oil. Better isn't the right word, more layered is more accurate.
How many essential oils should I blend together?
For beginners, two or three oils is the sweet spot. It's enough to create depth and longevity without making the formula too complex to understand or calculate safely.
As your knowledge grows, you can add more, but many experienced formulators find that fewer, well-chosen oils produce better results than large multi-oil blends.
Can I blend any essential oils together?
Most essential oils blend well together, but some combinations work better than others. Oils within the same aromatic family, all citrus, all woody, all floral, tend to be naturally compatible.
Oils from complementary families, like citrus and resinous, create interesting contrast. The best way to learn is to smell combinations on a test strip before committing them to a formula.
Does blending change the safety profile of essential oils?
Yes, and this is important. When you blend oils, the total percentage of all essential oils combined is what matters for safety, not each oil individually.
Some oils also have specific concentration limits that apply regardless of what else is in the formula. If you're formulating for skin contact, always calculate your totals and check the individual limits of each oil you're using.
Is blending essential oils different for candles versus skincare?
The blending principles, actions, top/middle/base notes, synergy, modulation, apply across all formats.
The main practical difference is heat. Candle and balm making involves heat, and heat affects how aromatic compounds behave. Top note oils with lower flash points need to be added at cooler temperatures to preserve their character in the finished product.
