Understanding Carrier Oils: The Foundation of Botanical Skincare

Understanding Carrier Oils: The Foundation of Botanical Skincare

Every botanical balm, facial oil, and plant-based skincare product begins with a foundation — and in most cases, that foundation is a carrier oil. Carrier oils are the unsung heroes of botanical skincare: the ingredients that make everything else possible, that determine how a product feels on the skin, how well it absorbs, and how effectively it delivers the botanicals it carries.

At Bovanique, carrier oil selection is one of the most considered parts of our formulation process. We don’t choose oils for convenience or cost — we choose them because of what they bring to each specific formulation. Understanding carrier oils is, in many ways, the key to understanding botanical skincare itself.

This article is our comprehensive guide to carrier oils: what they are, how they differ from essential oils, what makes each one unique, and how we use them in our handcrafted small-batch formulations.

Carrier oils are plant-derived fatty oils extracted from seeds, nuts, or kernels. Unlike essential oils, they can be applied directly to the skin and form the base of botanical formulations. Each carrier oil has its own fatty acid profile, texture, and skin-supporting properties — making carrier oil selection one of the most important decisions in botanical skincare formulation.

What Are Carrier Oils?

Carrier oils are plant-derived oils extracted from the seeds, nuts, or kernels of plants. Unlike essential oils — which are highly concentrated aromatic compounds extracted from flowers, leaves, or bark — carrier oils are fatty oils that can be applied directly to the skin. They are called “carrier” oils because they carry other ingredients — essential oils, botanical extracts, and active compounds — into the skin.

Most carrier oils are extracted through cold-pressing, a mechanical process that presses the oil from the plant material without heat. Cold-pressing is preferred in botanical skincare because it preserves the oil’s naturally occurring fatty acids, antioxidants, vitamins, and other active compounds that can be degraded by heat-based extraction methods.

Carrier oils are not simply neutral bases. Each one has its own fatty acid profile, its own texture, its own absorption rate, and its own set of naturally occurring compounds that contribute to the overall effect of a formulation. Choosing the right carrier oil — or the right combination of carrier oils — is one of the most important decisions in botanical skincare formulation.

🌿 Did You Know?

The use of plant-derived oils in skincare predates recorded history. Ancient Egyptians used sesame, castor, and moringa oils in cosmetic preparations and skin treatments. Ayurvedic medicine developed sophisticated systems for classifying and using plant oils based on their properties and their effects on different skin types — a tradition that continues to inform modern botanical skincare. Many of the carrier oils used in contemporary formulations have been used in traditional skincare practice for thousands of years, and the research record is increasingly helping explain why they have endured.

Why Carrier Oils Matter in Botanical Skincare

The carrier oil in a formulation does far more than simply dilute other ingredients. It determines the texture and feel of the finished product, influences how quickly it absorbs into the skin, affects how long it stays on the skin’s surface, and contributes its own active compounds to the overall formulation.

Different carrier oils have fundamentally different fatty acid profiles — and fatty acids matter enormously in skincare. The skin’s natural barrier is composed largely of lipids, and the fatty acids in carrier oils interact directly with this barrier. Oils high in linoleic acid (omega-6), for example, are associated with supporting barrier function and are often well-suited to dry and sensitive skin. Oils high in oleic acid (omega-9) tend to be richer and more occlusive, making them better suited to very dry or mature skin. Oils with a balanced profile may be suitable for a wider range of skin types.

Beyond fatty acids, many carrier oils contain naturally occurring vitamins, antioxidants, and plant sterols that contribute to their skin-supporting properties. Rosehip oil, for example, is valued for its vitamin A precursors and antioxidant content. Tamanu oil is studied for its unique fatty acid profile and its traditional use in wound care. Neem oil contains compounds with well-documented antimicrobial properties.

In short: the carrier oil is not a passive ingredient. It is an active contributor to every formulation it appears in.

Carrier Oils vs. Essential Oils: Key Differences

Property Carrier Oils Essential Oils
Source Seeds, nuts, kernels (cold-pressed) Flowers, leaves, bark, roots (steam distilled)
Concentration Ready to use; applied directly to skin Highly concentrated; must always be diluted
Scent Mild or neutral Strong, characteristic aroma
Typical use level Majority of formulation (50–99%) Small amounts only (typically 1–3%)
Primary role Nourish skin, support barrier, carry other ingredients Contribute specific properties, fragrance, aromatherapy
Safety Generally safe for direct skin application Never apply undiluted to skin
Examples Jojoba, rosehip, sweet almond, macadamia Lavender, chamomile, frankincense, camphor

In a well-formulated botanical balm, carrier oils and essential oils work together: the carrier oil forms the base and delivers nourishment, while the essential oils contribute their specific properties in appropriately diluted, skin-safe amounts.

Common Carrier Oils and Their Unique Characteristics

Here is an overview of the carrier oils we use at Bovanique, along with the characteristics that make each one suited to its role in our formulations.

Jojoba Oil (Simmondsia chinensis)

Technically a liquid wax rather than a true oil, jojoba is one of the most versatile and stable carrier oils in botanical skincare. Its molecular structure closely resembles the skin’s own sebum, which contributes to its excellent skin compatibility and its ability to absorb readily without leaving a greasy residue. Jojoba is non-comedogenic, highly stable (it resists oxidation far better than most oils), and well-tolerated by most skin types including oily and acne-prone skin. It forms an excellent base for balms and body care formulations where a lightweight, non-greasy feel is important.

Sweet Almond Oil (Prunus dulcis)

Cold-pressed from the kernels of sweet almonds, sweet almond oil is a classic carrier oil valued for its mild, nourishing character and its suitability for sensitive skin. It has a balanced fatty acid profile — rich in oleic acid with meaningful amounts of linoleic acid — that helps support skin hydration without feeling heavy. Sweet almond oil absorbs well, has a light texture, and blends naturally with a wide range of essential oils and botanical extracts. It is a foundational oil in many of our balm formulations. Note: not suitable for those with tree nut allergies.

Rice Bran Oil (Oryza sativa)

Extracted from the outer bran layer of rice grains, rice bran oil is a lightweight, stable carrier oil with excellent oxidative stability. It is rich in vitamin E, gamma-oryzanol (a compound associated with antioxidant activity), and plant sterols. Rice bran oil absorbs readily into the skin, has a non-greasy feel, and is well-suited to formulations intended for everyday use. Its stability makes it a practical choice in balm formulations where shelf life is a consideration.

Macadamia Oil (Macadamia integrifolia)

Macadamia oil is notable for its exceptionally high palmitoleic acid content — a fatty acid that occurs naturally in young skin but decreases with age. This makes macadamia oil a particularly thoughtful choice for mature skin formulations, where it may help support the skin’s natural lipid environment. It has a rich, silky texture that absorbs well without heaviness, and it is highly stable due to its high saturated fat content. Macadamia oil is a natural fit for our facial and mature skin formulations.

MCT Oil — Fractionated Coconut Oil (Cocos nucifera)

MCT (medium-chain triglyceride) oil is derived from coconut oil through a fractionation process that removes the long-chain fatty acids, leaving a lightweight, odourless, and exceptionally stable oil. Unlike whole coconut oil, fractionated coconut oil remains liquid at room temperature and is non-comedogenic. It absorbs quickly, has a dry, non-greasy feel, and acts as an excellent carrier for essential oils and other active ingredients. Its stability and neutral character make it a practical base oil in many of our formulations.

Rosehip Seed Oil (Rosa canina / Rosa rubiginosa)

Rosehip oil is one of the most studied carrier oils in botanical skincare, valued for its high concentration of linoleic acid (omega-6), alpha-linolenic acid (omega-3), and naturally occurring vitamin A precursors. It is associated with supporting healthy cell turnover, skin barrier function, and a more even-looking skin tone. Rosehip oil has a relatively lightweight texture and absorbs well, making it suitable for facial formulations. Because it is rich in polyunsaturated fatty acids, it is more susceptible to oxidation than more stable oils — freshness and proper storage matter. We use it as a key ingredient in our GlowGuard Botanical Balm, where it works alongside frankincense and calendula to help support the appearance of healthy, radiant skin.

Neem Oil (Azadirachta indica)

Neem oil is one of the most distinctive carrier oils in botanical skincare — and one of the most potent. Cold-pressed from the seeds of the neem tree, it has a strong, characteristic earthy scent and a rich, dense texture. Neem oil contains a range of naturally occurring compounds, including azadirachtin and nimbidin, that have been studied for their antimicrobial and skin-supporting properties. It is traditionally used in Ayurvedic skincare for scalp health, skin conditions, and as a general skin tonic. Because of its potency and strong scent, neem oil is typically used in small proportions within a formulation, blended with other carrier oils to balance its character.

Tamanu Oil (Calophyllum inophyllum)

Tamanu oil is a dark green, richly textured oil cold-pressed from the nuts of the tamanu tree, native to tropical regions of Southeast Asia and the Pacific Islands. It has a long history of use in traditional Pacific Island skincare, particularly for wound healing, scar support, and skin conditions. Tamanu oil contains a unique combination of fatty acids and a compound called calophyllolide, which has been studied for its skin-supporting properties. It is a heavier oil that is typically used in targeted formulations or blended with lighter carrier oils. Its distinctive character makes it a thoughtful addition to formulations intended for skin that needs extra support.

Black Seed Oil (Nigella sativa)

Black seed oil — also known as black cumin oil or nigella oil — is cold-pressed from the seeds of Nigella sativa, a flowering plant native to Southwest Asia and the Mediterranean. It has been used in traditional medicine across many cultures for thousands of years and contains a range of naturally occurring compounds, including thymoquinone, which has been studied for its antioxidant and skin-supporting properties. Black seed oil has a distinctive, slightly spicy scent and a medium-weight texture. It is associated with supporting skin comfort and a balanced skin environment, and is used in formulations intended for reactive or sensitive skin.

Calendula Infused Oil

Calendula infused oil is made by infusing dried calendula flowers in a carrier oil — typically sunflower or olive oil — over an extended period, allowing the plant’s naturally occurring compounds to transfer into the oil. The result is a golden, gently fragrant oil that carries calendula’s skin-soothing properties in a skin-compatible, ready-to-use form. Calendula infused oil is one of the most versatile and gentle botanical oils in skincare, well-suited to sensitive, reactive, and delicate skin. It is a foundational ingredient in several of our formulations. Read more: Calendula for Skin: Benefits, Uses & Why We Love This Botanical

Arnica Infused Oil

Arnica infused oil is made by infusing dried arnica flowers in a carrier oil, allowing arnica’s active compounds — including sesquiterpene lactones and flavonoids — to transfer into the oil. The resulting infused oil carries arnica’s well-documented properties for supporting muscle recovery, helping reduce the appearance of bruising, and supporting the body’s natural response to physical exertion. It forms the foundation of our muscle and body care formulations. Read more: Arnica for Muscle Recovery & Body Comfort: What You Need to Know

Lavender Infused Oil

Lavender infused oil is made by infusing dried lavender flowers in a carrier oil, capturing lavender’s calming, skin-soothing properties in a gentle, skin-compatible form. Unlike lavender essential oil — which is highly concentrated and must be used in small amounts — lavender infused oil delivers a softer, more diffuse version of lavender’s benefits, making it particularly well-suited to sensitive skin formulations and products intended for use on delicate areas.

Turmeric Infused Oil

Turmeric infused oil is made by infusing dried turmeric root in a carrier oil, allowing curcumin and other naturally occurring compounds to transfer into the oil. Turmeric has a long history of use in Ayurvedic skincare and traditional medicine, and its active compounds are associated with antioxidant and anti-inflammatory activity. Turmeric infused oil has a warm, golden colour and a distinctive earthy character. It is used in our body care formulations where its properties complement other recovery-supporting botanicals.

How We Choose Carrier Oils at Bovanique

Carrier oil selection at Bovanique is guided by a set of principles that reflect our broader formulation philosophy: every ingredient must earn its place, and every combination must be chosen for how the ingredients work together, not simply for the properties of each ingredient in isolation.

When developing a formulation, we consider several factors for each carrier oil:

Fatty acid profile — Does the oil’s fatty acid composition suit the intended skin type and concern? A formulation for mature, dry skin calls for different oils than one intended for everyday body care or scalp health.

Texture and absorption — How does the oil feel on the skin? How quickly does it absorb? A balm intended for overnight facial use can carry richer, slower-absorbing oils than one intended for post-activity body care.

Stability — How susceptible is the oil to oxidation? Oils rich in polyunsaturated fatty acids (like rosehip) require more careful handling and storage than more stable oils (like jojoba or MCT). In a small-batch operation, stability is a practical consideration that affects both quality and shelf life.

Compatibility with other ingredients — How does the oil interact with the essential oils, botanical infusions, beeswax, and butters in the formulation? Some oils enhance the delivery of other active ingredients; others may compete or conflict.

Sourcing and quality — Where does the oil come from, and how was it processed? Cold-pressed, unrefined oils retain more of their naturally occurring compounds than refined alternatives. We prioritise quality and freshness in our sourcing, particularly for oils that are more susceptible to oxidation.

The result of this process is formulations where every carrier oil has a specific reason for being there — and where the combination of oils creates something more effective than any single oil could achieve alone.

How to Choose the Right Carrier Oil for Your Skin

While the best approach is to use a well-formulated product where carrier oil selection has already been considered, understanding the general principles can help you make more informed choices about the botanical skincare products you use.

Dry and mature skin tends to benefit from richer oils with higher oleic acid content — such as macadamia, sweet almond, or rosehip — that help support moisture retention and a more nourished-looking complexion.

Sensitive and reactive skin often responds well to gentle, well-tolerated oils like jojoba, sweet almond, or calendula infused oil, which are associated with supporting skin comfort and barrier function without the risk of irritation.

Oily and combination skin may prefer lighter, faster-absorbing oils with a higher linoleic acid content — such as jojoba or MCT oil — that absorb readily without contributing to congestion.

Scalp and hair care calls for oils that absorb well into the scalp without leaving heavy residue — lighter oils like jojoba, rice bran, or MCT oil are often well-suited, sometimes combined with more targeted botanicals like neem or black seed oil.

Body and muscle care formulations often benefit from a combination of stable base oils with good absorption and targeted botanical infusions — like arnica or turmeric — that contribute specific recovery-supporting properties.

Carrier Oils in Bovanique Formulations

Carrier oils form the foundation of every Bovanique formulation. Here is how they appear across our range:

Key Takeaways

  • Carrier oils are plant-derived fatty oils that form the foundation of botanical skincare formulations — they are not passive bases but active contributors with their own fatty acid profiles, antioxidants, and skin-supporting properties.
  • The choice of carrier oil significantly influences a formulation’s texture, absorption, stability, and effectiveness for different skin types and concerns.
  • Carrier oils are fundamentally different from essential oils: they can be applied directly to the skin, they are used in much larger proportions, and they serve a different function in a formulation.
  • At Bovanique, carrier oil selection is guided by fatty acid profile, texture, stability, compatibility with other ingredients, and sourcing quality — every oil in every formulation has a specific reason for being there.
  • Botanical infused oils — such as our calendula, arnica, lavender, and turmeric infusions — are a distinct category that combines the nourishing properties of a carrier oil with the active compounds of a botanical ingredient.

Frequently Asked Questions About Carrier Oils

What is the difference between a carrier oil and an essential oil?

Carrier oils are fatty plant oils that can be applied directly to the skin and form the base of botanical formulations. Essential oils are highly concentrated aromatic compounds that must always be diluted in a carrier oil before skin application. In a botanical balm or skincare product, carrier oils typically make up the majority of the formulation, while essential oils are used in small amounts — usually 1–3% — for their specific properties and fragrance.

Can carrier oils be applied directly to the skin?

Yes — carrier oils can be applied directly to the skin, unlike essential oils which must always be diluted. However, they are most effective when incorporated into a well-formulated product that combines them with complementary ingredients. As with any new skincare ingredient, a patch test is always a sensible first step, particularly for those with sensitive or reactive skin or known nut allergies.

How do I know which carrier oil is right for my skin?

The right carrier oil depends on your skin type, your skin concerns, and the specific formulation you’re using. As a general guide: dry and mature skin tends to benefit from richer oils like rosehip or macadamia; sensitive skin often responds well to gentle oils like jojoba or calendula infused oil; oily skin may prefer lighter, faster-absorbing options like jojoba or MCT oil. The best approach is to use a well-formulated product where carrier oil selection has already been considered for your skin type and concern.

What is a botanical infused oil?

A botanical infused oil is made by infusing plant material — dried flowers, roots, or herbs — in a carrier oil over an extended period, allowing the plant’s naturally occurring compounds to transfer into the oil. The result is an oil that combines the nourishing properties of the carrier oil with the active compounds of the botanical. Our calendula, arnica, lavender, and turmeric infused oils are all made using this traditional process. Learn more about botanical infusions →

Are carrier oils comedogenic (do they clog pores)?

Comedogenicity varies significantly between carrier oils. Jojoba and MCT oil are considered non-comedogenic and are generally well-tolerated by oily and acne-prone skin. Richer oils like macadamia or sweet almond oil are better suited to dry and mature skin. In a well-formulated product, the combination of oils and other ingredients is designed to be appropriate for the intended skin type. If you have oily or acne-prone skin, look for formulations that use lighter, non-comedogenic carrier oils as their base.

What does “cold-pressed” mean and why does it matter?

Cold-pressing is a mechanical extraction method that presses oil from plant material without applying heat. This is important in botanical skincare because heat can degrade the naturally occurring fatty acids, vitamins, antioxidants, and other active compounds that give carrier oils their skin-supporting properties. Cold-pressed oils retain more of their naturally occurring compounds than heat-extracted or refined alternatives — which is why we prioritise cold-pressed sourcing in our formulations.

How should carrier oils be stored?

Carrier oils — particularly those rich in polyunsaturated fatty acids, like rosehip — are susceptible to oxidation and should be stored in a cool, dark place away from direct sunlight and heat. Amber glass bottles help protect oils from light degradation. Oils that have gone rancid (indicated by an off, unpleasant smell) should not be used on the skin. At Bovanique, we work in small batches specifically to ensure freshness and quality in every formulation.
