Carrier oils are plant-based oils (like jojoba, sweet almond, coconut, or argan) that are used to dilute concentrated essential oils so they can be safely applied to the skin without irritation.

What Are Carrier Oils?

Carrier oils are usually cold-pressed vegetable oils made from the seeds, nuts, or kernels of plants, and they are called “carrier” oils because they carry essential oils onto your skin. They are sometimes called “fixed oils” because they are stable, do not evaporate like essential oils, and usually have little to no scent or only a mild nutty aroma.

Key traits

  • Derived from plants (seeds, nuts, kernels, or fruits).
  • Non-volatile (do not evaporate quickly).
  • Typically mild or neutral scent so they don’t overpower essential oils.
  • Rich in fatty acids, vitamins, and other skin-loving compounds.

Think of essential oils as the “concentrated actives” and carrier oils as the nourishing base that makes those actives gentle and usable on real skin.

Why Are Carrier Oils Used?

Carrier oils are essential for safe aromatherapy and topical essential-oil use.

Main purposes

  1. Dilution and safety
    • Essential oils are very potent and can irritate or sensitize the skin if used undiluted.
 * Carrier oils dilute this strength while preserving the benefits, reducing the risk of burns, redness, and allergic reactions.
  1. Better absorption and glide
    • Carrier oils help essential oils spread evenly and absorb more comfortably into the skin.
 * They provide “slip” for massage, making the hands glide smoothly without tugging the skin.
  1. Nourishing the skin
    • Many carrier oils hydrate, soften, and protect the skin thanks to fatty acids, vitamin E, and antioxidants.
 * They can be tailored to support dry, oily, sensitive, or aging skin depending on which oil you pick.

Common Types of Carrier Oils

Here are some popular carrier oils and what they’re often used for.

Everyday favorites

  • Jojoba oil – Technically a liquid wax, very close to skin’s natural sebum, suitable for almost all skin types, absorbs easily, often used for face serums and acne-prone skin.
  • Sweet almond oil – Lightweight, mildly nutty, commonly used for massage and general body moisturising.
  • Fractionated coconut oil – Liquid at room temperature, stable, light, and popular as a neutral carrier in many DIY blends.
  • Argan oil – Rich in vitamins A and E and monounsaturated fats, used for dry skin, hair care, and anti-aging formulas.
  • Avocado oil – Heavier, nourishing, good for dry or mature skin.
  • Grapeseed oil – Light and fast-absorbing, often chosen for massage and oilier skin types.
  • Olive oil (extra-virgin) – Used in aromatherapy and skincare as a carrier; rich in fatty acids and sterols, great for dry skin and cleansing oils.

Skin-type examples (quick guide)

  • For all skin types: jojoba oil, sweet almond oil.
  • For dry or aging skin: rosehip oil, argan oil, avocado oil.
  • For oily skin: grapeseed oil, castor oil (usually blended).
  • For sensitive skin: gentle, simple oils like jojoba and sweet almond (always patch test).

How Do You Use Carrier Oils?

Here’s how carrier oils show up in everyday routines.

  1. Diluting essential oils for skin
    • Mix a small amount of essential oil into a larger amount of carrier oil to create safe body, face, or spot-treatment blends.
  1. Massage oils
    • Carrier oils like sweet almond, grapeseed, or jojoba form the base of massage oils, with essential oils added for scent and targeted benefits.
  1. Facial and body skincare
    • Used as facial oils, cleansing oils, body oils, or in serums, often chosen by skin type (e.g., rosehip for aging skin, grapeseed for oily skin).
  1. Hair and scalp care
    • Argan, coconut, and castor oils are commonly used as carriers in hair oils or scalp treatments, sometimes with essential oils like rosemary or tea tree.

A Quick Practical Example

Imagine you want a relaxing lavender body oil:

  • You choose jojoba oil as your carrier because it’s light and suits most skin.
  • You add a few drops of lavender essential oil into a tablespoon or more of jojoba oil to dilute it properly.
  • The jojoba nourishes skin and helps the lavender spread and absorb, while keeping the lavender gentle enough for regular use.
