Carrier Oils Guide
Carrier oils dilute essential oils for safe topical use. Each has unique properties — absorption rate, shelf life, skin type suitability, and comedogenic rating.
Apricot Kernel
Prunus armeniaca
A gentle, nourishing oil similar to almond but lighter, perfect for delicate and aging skin.
Apricot kernel oil has a fatty acid profile similar to sweet almond but with a lighter texture, containing oleic acid (~58-74%) and linoleic acid (~20-34%) that provide excellent emollient properties without heaviness. It is particularly rich in vitamin A (retinol precursors) and vitamin E (gamma-tocopherol), which promote cellular regeneration and protect against premature aging caused by environmental stressors. The oil has mild anti-inflammatory properties and is gentle enough for use around the delicate eye area, on infant skin, and on inflamed or sensitized skin conditions. Its rapid absorption, subtle nutty aroma, and smooth glide make it a preferred choice for facial massage and luxury skincare formulations.
Argan
Argania spinosa
A luxurious Moroccan oil prized for its anti-aging and deeply nourishing properties.
Argan oil is exceptionally rich in oleic acid (~43-49%), linoleic acid (~29-36%), and contains rare sterols (schottenol and spinasterol) not commonly found in other plant oils. It provides unusually high concentrations of vitamin E (tocopherols ~60-90 mg/100g), squalene, and polyphenols that work synergistically to combat oxidative stress and promote skin elasticity. Clinical studies have demonstrated its ability to improve skin hydration by restoring the barrier function of the stratum corneum. Its non-comedogenic rating of 0 makes it one of the safest oils for facial use across most skin types, particularly benefiting mature and dry skin.
Avocado
Persea americana
A thick, deeply penetrating oil rich in vitamins A, D, and E for intensive skin repair.
Avocado oil is uniquely rich in palmitoleic acid (~3-10%), an omega-7 fatty acid that naturally decreases in human skin with age, making this oil particularly valuable for mature skin care. It contains the highest concentration of unsaponifiable matter (up to 11%) of any fruit oil, including phytosterols, fat-soluble vitamins (A, D, E, K), and lecithin, which enhance its skin-penetrating ability. The oil has demonstrated wound-healing and anti-inflammatory properties in clinical studies, partly attributed to its polyhydroxylated fatty alcohol content. Its thick consistency makes it best used as 10-25% of a carrier blend rather than as a standalone oil for most applications.
Castor
Ricinus communis
A thick, viscous oil famous for promoting hair growth and deep-cleansing skin applications.
Castor oil is unique among carrier oils due to its extraordinarily high concentration of ricinoleic acid (~85-92%), a rare hydroxylated fatty acid that gives the oil its characteristic viscosity and potent anti-inflammatory properties. Ricinoleic acid has been shown to activate prostaglandin EP3 receptors, contributing to the oil's well-documented analgesic and anti-inflammatory effects when applied topically as castor oil packs. The oil acts as a humectant, drawing moisture to the skin, and is widely used to promote hair thickness and eyelash growth, though peer-reviewed evidence for hair growth is limited. Its thick consistency makes it best blended at 10-20% with lighter carriers for massage use.
Evening Primrose
Oenothera biennis
A therapeutic oil renowned for its high GLA content, used for hormonal skin concerns.
Evening primrose oil is one of the richest plant sources of gamma-linolenic acid (GLA, ~8-14%), an omega-6 fatty acid that serves as a precursor to anti-inflammatory prostaglandins (PGE1). GLA is critical for maintaining skin barrier function, and supplementation has been shown to improve skin moisture, elasticity, and firmness in clinical trials. The oil is particularly valued for hormonally-influenced skin conditions, with research supporting its use in managing PMS-related skin changes and menopausal dryness. It also contains linoleic acid (~65-80%), tryptophan, and phenolic compounds that contribute to its overall therapeutic profile.
Fractionated Coconut
Cocos nucifera
A lightweight, odorless coconut derivative that stays liquid and never goes rancid.
Fractionated coconut oil has been processed to remove long-chain fatty acids, leaving primarily capric (C10) and caprylic (C8) medium-chain triglycerides. These MCTs give the oil exceptional oxidative stability, a very light texture, and virtually no scent, making it ideal as a neutral carrier. It has natural antimicrobial properties due to its caprylic acid content, which can help protect the skin barrier. The oil absorbs quickly without leaving a greasy residue, making it particularly well-suited for roller bottle blends and body sprays.
Grapeseed
Vitis vinifera
A lightweight, astringent oil ideal for oily skin types and light massage applications.
Grapeseed oil contains one of the highest concentrations of linoleic acid (~66-75%) among common carrier oils, making it particularly beneficial for oily and acne-prone skin that is often deficient in this fatty acid. It is a rich source of proanthocyanidins (oligomeric proanthocyanidin complexes), which are powerful antioxidants estimated to be 20 times more potent than vitamin C. The oil has mild astringent properties that help tighten and tone the skin without clogging pores. Its very light texture and rapid absorption make it excellent for facial serums, though its high PUFA content means it has a shorter shelf life and should be stored in cool, dark conditions.
Hemp Seed
Cannabis sativa
An anti-inflammatory oil with an ideal omega-6 to omega-3 ratio for calming reactive skin.
Hemp seed oil has an optimal 3:1 ratio of omega-6 (linoleic acid ~55%) to omega-3 (alpha-linolenic acid ~20%) fatty acids, which closely matches the ratio recommended for human nutrition and skin health. It is one of the few plant oils that contains gamma-linolenic acid (GLA, ~1-4%), a potent anti-inflammatory compound that has been shown to reduce symptoms of atopic dermatitis and eczema. The oil is non-comedogenic (rating 0) despite its richness, making it safe for acne-prone skin where it can help regulate sebum production. It also contains chlorophyll, phytosterols, and minerals that contribute to its distinctive green color and skin-calming effects.
Jojoba
Simmondsia chinensis
A liquid wax ester that closely mimics human sebum, offering exceptional shelf stability.
Jojoba is technically a liquid wax ester rather than a true oil, composed primarily of long-chain monounsaturated fatty alcohols and acids (eicosenoic acid ~66-71%). Its molecular structure closely resembles human sebum, allowing it to regulate oil production by signaling the skin that sufficient moisture is present. Jojoba contains natural forms of vitamin E (tocopherols) and is highly resistant to oxidation, giving it one of the longest shelf lives among carrier oils. It forms a non-greasy protective layer on the skin that locks in moisture while still allowing the skin to breathe.
Moringa
Moringa oleifera
An ancient "ben oil" with exceptional oxidative stability and detoxifying skin benefits.
Moringa oil (also known as ben oil or behen oil) is remarkably rich in oleic acid (~65-78%) and behenic acid (~5-9%), giving it exceptional oxidative stability comparable to jojoba. It contains potent antioxidants including zeatin (a cytokinin plant hormone), quercetin, beta-sitosterol, and vitamin E at concentrations that slow cellular aging and protect against environmental damage. The oil has notable detoxifying properties and has been traditionally used to draw out impurities from the skin, supported by modern research showing its ability to adsorb heavy metals. Its silky, non-drying texture makes it a versatile addition to facial serums, hair treatments, and perfumery.
Olive
Olea europaea
A pantry staple with rich squalene content, best for intensive body and hair treatments.
Extra virgin olive oil is rich in oleic acid (~55-83%), squalene (~0.3-0.7%), and hydroxytyrosol, a polyphenol with one of the highest ORAC (antioxidant) values of any natural compound. The squalene content is noteworthy as it mirrors a lipid naturally produced by human sebaceous glands, aiding in skin barrier repair and moisture retention. Olive oil contains oleocanthal, a natural phenolic compound with anti-inflammatory properties comparable to ibuprofen at equivalent doses. While excellent for body treatments and hair masks, its heavier texture and moderate comedogenic rating make it less suitable for facial use on acne-prone skin.
Rosehip
Rosa canina
A potent regenerative oil high in trans-retinoic acid, favored for scars and hyperpigmentation.
Rosehip seed oil is one of the few plant oils containing natural trans-retinoic acid (tretinoin), a form of vitamin A that promotes cellular turnover and collagen synthesis. It is rich in polyunsaturated fatty acids, particularly linoleic acid (~44%) and alpha-linolenic acid (~33%), which are essential for maintaining skin barrier integrity. The oil also contains significant levels of beta-carotene and lycopene, contributing to its characteristic golden-orange color and potent antioxidant activity. Clinical research supports its efficacy in reducing the appearance of scars, stretch marks, and UV-induced hyperpigmentation.
Sunflower
Helianthus annuus
A light, affordable oil clinically shown to strengthen the skin barrier in premature infants.
High-linoleic sunflower oil contains approximately 59-72% linoleic acid, a critical component of ceramides that form the skin's moisture barrier. Clinical studies in neonatal care have demonstrated that topical application of sunflower oil significantly reduces transepidermal water loss (TEWL) and nosocomial infections in premature infants, making it one of the most evidence-backed carrier oils for sensitive skin. It provides a rich source of vitamin E (alpha-tocopherol ~40-60 mg/100g), which supports skin repair and protection against UV-induced free radical damage. Its non-comedogenic rating, light texture, and affordability make it an excellent everyday carrier oil for both skincare and aromatherapy blends.
Sweet Almond
Prunus dulcis
A versatile, mild carrier oil rich in vitamin E, ideal for massage and skincare blends.
Sweet almond oil is rich in oleic acid (62-86%) and linoleic acid (20-30%), providing deep moisturization without excessive greasiness. It contains high levels of vitamin E (alpha-tocopherol), which acts as a natural antioxidant to protect skin from oxidative stress and UV damage. The oil has mild anti-inflammatory properties and is easily absorbed, making it an excellent emollient for soothing eczema, psoriasis, and general dryness. Its light texture and neutral scent make it one of the most popular base oils for aromatherapy massage blends.
Tamanu
Calophyllum inophyllum
A potent healing oil with unique calophyllolide compounds for scar tissue and skin regeneration.
Tamanu oil contains unique bioactive compounds not found in any other plant oil, including calophyllolide and delta-tocotrienol, which have demonstrated significant anti-inflammatory, antimicrobial, and wound-healing activity in peer-reviewed studies. It promotes the formation of new tissue (cicatrization), making it particularly effective for scars, burns, cuts, and post-surgical healing. The oil is rich in oleic acid (~34-41%), linoleic acid (~21-28%), and stearic acid (~12-15%), along with coumarins and xanthones that provide UV-protective and antioxidant benefits. Its thick, dark green color and strong nutty aroma mean it is typically used at 10-50% dilution in a lighter carrier oil.
