Not All Facial Oils Are the Same: Understanding Fatty Acids in Botanical Oils
Two bottles can both say “100% botanical facial oil” and still feel completely different on your skin.
One disappears almost instantly. Another feels richer and more cushioning. One may suit a lightweight daytime ritual, while another feels more appropriate when your skin is dry and craving deeper nourishment.
Why?
Part of the answer lies in something you can't see when you look at the bottle:
its fatty-acid composition.
Understanding this simple piece of oil science can change the way you choose facial oils—and help you move beyond the idea that all natural oils do essentially the same thing.
First, Why Does Your Skin Need Lipids?
Your skin barrier—the outermost protective layer of your skin—isn't built from water alone.
It contains an organized lipid matrix that includes ceramides, cholesterol and free fatty acids. Together, these components help maintain barrier integrity and limit excessive water loss from the skin.
This is why healthy-looking skin requires more than simply adding hydration.
Think of it this way:
💧 Water helps hydrate the skin.
🟡 Lipids help support the barrier that keeps that moisture from escaping too easily.
Botanical oils don't provide water. Instead, they primarily contribute emollient lipids that can help soften the skin, improve suppleness and complement a well-formulated moisturizing routine.
And this is where the differences between oils become interesting.
What Are Fatty Acids?
Fatty acids are major components of the triglycerides that make up most plant oils.
Two names you'll frequently encounter in botanical skincare are:
Linoleic Acid
Linoleic acid is an omega-6 essential fatty acid.
Oils with relatively high linoleic-acid content often have a lighter sensory profile and can be appealing when you want nourishment without an excessively rich finish.
Oleic Acid
Oleic acid is an omega-9 monounsaturated fatty acid.
Oils containing substantial oleic acid often feel richer and more emollient, although the final skin feel of an oil depends on its entire chemical composition—not one fatty acid alone.
Neither fatty acid is simply “better.”
The important question is:
What does your skin need, and what kind of sensory experience are you looking for?
Five African Botanical Oils. Five Different Personalities.
At MEROË, we don't see botanical oils as interchangeable ingredients.
Each botanical has its own origin, composition, texture and ritual character.
Prickly pear seed oil is valued for its naturally high proportion of linoleic acid, alongside oleic acid and naturally occurring antioxidant compounds such as tocopherols.
Its elegant texture makes it particularly interesting for facial care when you want concentrated botanical nourishment without an excessively heavy finish.
Consider it when your ritual focuses on: Radiance • Suppleness • Antioxidant care • Lightweight nourishment
Kalahari melon seed oil is another botanical oil notable for its linoleic-acid-rich profile.
Traditionally associated with the Kalahari region of Southern Africa, this lightweight seed oil offers a beautiful option for people who enjoy facial oils but dislike a particularly rich or heavy skin feel.
Consider it when your ritual focuses on: Lightweight nourishment • Softness • Balance • Barrier support
Baobab seed oil offers a richer sensory experience and contains a mixture of oleic, linoleic and palmitic fatty acids, with the exact proportions varying naturally according to source and processing.
Its emollient character makes it particularly appealing when skin feels dry, rough or depleted.
Consider it when your ritual focuses on: Deep nourishment • Softness • Comfort • Dry-skin care
Frankincense is widely recognized for its aromatic resin, but frankincense seed oil is a different material obtained from the seeds.
Its fatty-acid composition can vary by Boswellia species and growing conditions, making sourcing and botanical identification especially important.
Rather than treating frankincense seed oil as interchangeable with frankincense essential oil, it should be understood as its own lipid-rich botanical ingredient.
Consider it when your ritual focuses on: Botanical nourishment • Skin conditioning • A refined nighttime ritual
Why Cold Pressing Matters
Fatty-acid composition is only part of the story.
How an oil is extracted and processed also matters.
Cold pressing mechanically extracts oil without relying on the high-temperature refining processes commonly used for heavily processed oils.
For premium botanical skincare, minimal processing can help preserve more of the oil's natural character, including some of its naturally occurring minor compounds.
This is one reason MEROË emphasizes cold-pressed, unrefined botanical oils.
The goal isn't to transform the botanical into something unrecognizable.
It's to preserve its character as thoughtfully as possible.
Does a More Expensive Oil Automatically Mean a Better Oil?
No.
Price alone doesn't determine whether an oil is right for your skin.
Botanical rarity, seed yield, harvesting methods, geographic origin, extraction, certification, packaging and supply chain can all influence cost.
Prickly pear seed oil, for example, requires a substantial amount of fruit and seed material to produce relatively small quantities of oil, contributing to its premium positioning.
But skincare shouldn't become a competition over which oil is the most expensive.
The better question remains:
Which botanical profile best complements your skin and your ritual?
How Do You Choose?
Instead of choosing facial oil because it is trending, start with how your skin currently feels.
If your skin feels dry and depleted:
Look toward richer, more emollient botanical profiles.
Explore: Baobab • Argan
If you want lightweight nourishment:
Consider oils with a lighter sensory character.
Explore: Kalahari Melon • Prickly Pear
If your priority is radiance and a refined facial ritual:
Consider a lightweight antioxidant-rich botanical.
Explore: Prickly Pear Seed Oil
If you want a richer nighttime ritual:
Layering or pairing complementary oils can provide a more enveloping experience.

Your skin can also change with the season, climate, age and the rest of your skincare routine.
There doesn't have to be one “perfect oil” forever.
One Oil—or a Ritual?
This is where the MEROË philosophy goes beyond selling individual bottles.
Different botanical oils provide different fatty-acid profiles, textures and sensory experiences.
Instead of asking every botanical to do everything, our rituals pair complementary oils around a particular skin goal.
One may provide lightweight conditioning.
Another may provide richer emollience.
Another may become the concentrated finishing step.
This creates a ritual built around intentional botanical selection rather than simply using more product.
The MEROË Philosophy
Nature doesn't produce one universal oil for every skin need.
And we don't believe skincare should treat botanical oils as if it does.
MEROË explores African botanical oils through both heritage and modern skin science—looking at where they come from, how they are produced, what they contain and how they can thoughtfully complement a skincare ritual.
Because choosing facial oil shouldn't begin with:
“Which oil is popular?”
It should begin with:
“What does my skin need?”
