Macadamia nuts are some of the most sought-after ingredients in the cosmetic industry - and it’s no surprise why. When cold-pressed into a carrier oil, they produce a nutrient-rich oil packed with vitamins, minerals and fatty acids that can help nourish and revitalise the skin and hair.
In this blog, we’ll explore what Macadamia Oil is, its many benefits for skin and hair, and how to safely incorporate it into your beauty and personal care routine.
What is Macadamia Oil?
Macadamia Nut Oil, also known as Macadamia Oil, is a natural, plant-based carrier oil extracted from the nuts of the Australian macadamia tree (Macadamia integrifolia). Rich in fatty acids and other beneficial compounds, it's widely used in skincare, haircare and aromatherapy for its nourishing and moisturising properties.
Native to Australia, macadamia trees have a long history of use by First Nations people, with some sources suggesting a connection dating back tens of thousands of years. Today, people around the world are enjoying the many benefits of Macadamia Oil for skin and hair
Once the nuts and seeds are cold pressed and refined, the result is a versatile carrier oil that absorbs well into the skin and leaves a smooth, silky finish. It is commonly used in massage oils, skincare formulations, and as a base for diluting essential oils.
The oil also contains squalene, a lipid naturally produced by human skin that helps maintain moisture and supports the skin barrier. This makes Macadamia Oil particularly appealing for mature and dry skin.

Is Macadamia Oil Safe?
Macadamia Oil is generally considered safe when used topically on most skin types. However, there are some considerations for its use.
Because it is derived from the nuts of the Macadamia tree, do not use Macadamia Oil if you have a nut (or tree nut) allergy.
Before using Macadamia Oil, we recommend performing a skin patch test on a small area of the skin to check for a reaction. Those with sensitive skin should perform the test over at least 48 hours. If you develop allergy symptoms, discontinue.
As a carrier oil, we do not recommend ingesting or using Macadamia Oil for culinary purposes. Our products are formulated for therapeutic and aromatherapy purposes and are not food grade.
When storing Macadamia Oil, ensure that it is kept away from direct sunlight in a cool space at room temperature to optimise its shelf life. Keep out of reach of children.
Macadamia Oil and Pregnancy
When used topically, Macadamia Carrier Oil is considered safe for use during any stage of pregnancy to nourish, replenish and soften the skin and hair.
If you are pregnant, we recommend reaching out to your GP or healthcare professional to discuss any concerns you have about implementing Macadamia Oil into your skincare routine. Do not ingest Macadamia Oil at any stage of your pregnancy.

FAQs
Is it safe to use Macadamia Oil on my face every day?
Yes, Macadamia Oil can be incorporated into your daily facial skincare routine to help moisturise and soften the skin. Start with a few drops on clean skin and adjust the amount to suit your skin type, before using it once or twice daily. Always patch test first, particularly if you have sensitive or acne-prone skin.
Can I use pure Macadamia Oil for dry hair?
Yes, Macadamia Nut Oil is particularly useful for dry, coarse or frizzy hair. Its fatty acids help condition and smooth the hair shaft, improving softness, manageability and shine. It can be used as a pre-shampoo treatment or applied sparingly to dry ends.

Macadamia Oil may help soften the appearance of fine lines by moisturising the skin and supporting its natural moisture barrier. However, it cannot prevent or reverse wrinkles caused by ageing, and results will vary depending on your skin type and condition.
