Benefits of Macadamia Nut Oil for Skin

We’re often asked how we choose the oils that go into our products. Today we’d like to spotlight one of our favorites, macadamia nut oil. There are many benefits of macadamia nut oil for skin care. It works well as a moisturizer. It is rich in nutrients, like omega fatty acids, nourishing vitamins, and hard-to-get nutrients like selenium—and then there are the knock-on benefits of selenium for skin, the benefits of the omegas, and so on.

Macadamia nut oil is also especially good for dry or aging skin. Many of our products are designed for dry, sensitive, and mature skin. If you have dry skin and are looking for help, read on to learn more about this fascinating nut oil and see why we choose to use it in our formulas!

More Than a Delicious Snack

From the beautiful state of Hawaii comes one of nature’s gifts: the macadamia nut! Long beloved on the islands, it grows on trees and is widely used, both for the benefits of macadamia nut oil in skin care and of course in its more popular role as a delicious food, appearing in many dishes and as the star ingredient in those famous chocolate-covered macadamia nuts found in tourist shops.

One of the best snacks around, macadamia nuts are a good source of healthy fats, protein, iron, vitamin A, thiamine, riboflavin, and niacin. Macadamias also contain calcium, magnesium, potassium and phosphorus. That’s quite a lot of nutrition in one nut!

Selenium Boost

Macadamia nuts also contain small amounts of selenium. Selenium is not only an antioxidant but one of the best brain foods around, and there are not too many foods that contain this vital nutrient. The benefits of selenium for skin include keeping inflammation low, preventing skin infections, and fighting free radicals.

A Powerful Skin Care Ally

Although they are a wonderful snack (one of my personal favorites), some of these nutrients also work wonders on the skin. The benefits of macadamia nut oil for skin care are numerous, and they begin with fatty acids.

A great deal of the way that we choose oils for our skincare has to do with the profile of the fatty acids. Macadamia nuts contain some of the highest levels of beneficial fatty acids found in a nut. Here are the details on them.

Beneficial Fatty Acids in Macadamia Nuts

Macadamia nuts contain high levels of some of the best fatty acids, including palmitoleic acid, which is particularly effective in the delay of premature aging in skin, and macadamia nut oil contains a whopping 17 - 23%!

As our bodies age, our skin becomes depleted of moisture and elasticity, making our skin tight, dry and ready for the formation of wrinkles. This is one of the key anti-aging benefits of macadamia nut oil for skin care: Palmitoleic acid reverses the appearance of this dry, tight skin, and there is even some evidence that it can assist in helping repair damaged skin cells. It is very moisturizing and perfect for dry, sensitive skin.Two other fatty acids that this wonderful nut contains are oleic and linoleic acid. Oleic acid is anti-inflammatory, making it a great choice for sensitive skin, and linoleic acid helps restore the skin’s barrier, keeping it hydrated. The combination of these three fatty acids moisturize skin and help it appear youthful, supple and smooth.

And Many Other Benefits of Macadamia Nut Oil for Skin Care!“Antis” for Health: Antioxidant, Antibacterial, Antifungal

The overall quality of macadamia nut oil is a lovely light-to-medium weight, making it easy to use. The chemical profile is quite similar to the natural sebum of our skin, and it penetrates deeply, while leaving a non-greasy finish. Its phenolic compounds work to reduce the oxidation of proteins and lipids in the body, which affect DNA and leave our bodies vulnerable to diseases such as cancer. These same compounds are also naturally antibacterial and antifungal, which assists in helping create a healthy barrier for our skin.

Long-Lasting Quality

At Ayr Skin Care, as formulators we want to bring nutrient-rich ingredients to our products, but we also want to choose ingredients that will have a good shelf life. There are some oils, like grapeseed oil, that have lovely qualities but a very short shelf life of 3 months. This is the reason that we do not use grapeseed oil.

Macadamia nut oil, on the other hand, has a very stable shelf life of up to two years. One thing that gives extra life to macadamia nut oil is that it contains tocotrienols, a special type of vitamin E that not only protects as an antioxidant but also helps extend and protect the quality of the oil itself.

Rich in Omega Fatty Acids

As of this wasn’t enough, one of the key benefits of macadamia nut oil for skin care is how rich it is in omega-3 and omega-6 fatty acids. The trick is getting just the right ratio between these two fatty acids, as our modern diet seems to exclude omega-3, and fast food gives us the wrong ratio of omega-6 entirely. Macadamia nuts are the perfect ratio between 3 and 6, making it a perfect snack, and a perfect fatty acid profile for sensitive skin.

In a Word: Perfect!

As you can see, there aren’t many carrier oils for skin care that are as perfect as macadamia nut oil. We find it makes our skin soft and supple, and helps protect it from free radicals. It brings just the right mixture of fatty acids, nutrients, and is a dream to formulate with.

We choose it as our main oil in our Tranquility Dry Body Oil, as well as making it a star player in our Pure Moisture Nourishing Face Cream. Caring for your skin should be easy, but as you can see it’s not enough to grab any oil or skin care moisturizer off the shelf and expect that it will care for your skin.

A great deal of thought goes into what we choose to include in our formulations. The benefits of macadamia nut oil for skin care are clear and bountiful, from the rich cell-restoring powers of palmitoleic acid to the inflammation-fighting benefits of selenium for skin. You will never find bleached, inexpensive oils in any of the products at Ayr Skin Care!
