9 Amazing Benefits & Uses of Kukui Nut Oil

Kukui nut oil has many notable benefits and uses, such as moisturizing the skin, preventing wrinkles and crow’s feet, soothing muscle aches and pains, protecting the immune system, eliminating inflammation, strengthening the hair, preventing dandruff, speeding wound healing and neutralizing free radical damage, among others. There are some side effects to using kukui nut oil, including gastrointestinal distress when consumed orally, as well as skin inflammation and possible toxicity if the oil passes its shelf life. However, responsible and timely use of this oil will generally not cause side effects in most people.

What is Kukui Nut Oil?

Kukui nut oil is derived from the state tree of Hawaii, the kukui nut tree, which is commonly known as the candlenut tree. Most commonly used as a massage oil, kukui nut oil is expeller pressed from the large nuts of the tree, which bears the scientific name Aleurites moluccanus. For thousands of years, the indigenous people of Hawaii have used this oil in religious ceremonies, paints, varnishes and even candle-making. However, it has become known to the wider world because of its impressive topical benefits to the skin and hair, as well as the immune system and muscles. The long list of benefits derived from kukui nut oil is attributed to its high level of poly- and monounsaturated fats – linoleic and linolenic – as well as vitamins C, D, E and other powerful antioxidants. 

Benefits & Uses of Kukui Nut Oil

People often use kukui nut oil when they struggle with joint pain, a weak immune system, arthritis, psoriasis, eczema, dry skin, dandruff, wrinkles, and premature signs of aging, blemishes, burns, scars, fresh wounds, split ends, hair loss, stretch marks, and sunburn.

Increases Hair Strength

A popular traditional use of kukui nut oil is to apply it to the hair in the form of a hair mask, mixing it in with shampoos or conditioners, or simply massaging it into the scalp and tips of the hair. The linoleic and linolenic fatty acids found in this oil are able to coat the hair, delivering key nutrients, moisturizing it, preventing breakage, and even improving the appearance and luster of hair. 

Prevents Dandruff

As an emollient substance, kukui nut oil is able to coat the skin and lock in moisture, thus preventing dry skin and dandruff that inevitably follows. This moisturizing quality of the oil also helps keep the hair follicles healthy and functioning, which can help prevent premature hair loss.

Controls Eczema

One of the most difficult skin conditions to keep under control is eczema, but kukui nut oil is not only able to deliver moisture to the skin, but can also hold it there, effectively soothing inflammation and preventing itchiness. This nut oil is also effective against symptoms of psoriasis and rosacea. 

Moisturizes Dry Skin

Dry, cracked skin of the hands and other parts of the body is not only painful, but a perfect breeding ground for infection. If you regularly work with your hands, or are often exposed to the elements, applying a sheen of kukui nut oil can prevent easy breakage of the skin, and promote the growth of new cells.

Heals Wound 

If you experience a scrape, scratch, bruise, cut or abrasion, you can apply a diluted form of kukui nut oil to the wound in order to speed healing, relieve pain and eliminate swelling, while also protecting the wound from possible infection. 

Minimizes Stretch Marks & Wrinkles

As we age, there are certain things that are unavoidable, such as wrinkles and age spots, but this antioxidant-rich oil is able to counter those effects, boosting collagen production and stimulating the sloughing of dead skin cells to make room for healthy new ones. In the case of stretch marks, for pregnant women or people experiencing rapid weight fluctuations, applying this oil daily can help minimize their appearance. 

Reduces Inflammation

The most popular use of kukui nut oil is in massage, and is still widely used today for this purpose. The rich blend of fatty acids, which have anti-inflammatory effects, can be absorbed into the skin and help to soothe sore muscles and joints, which is also why this oil is commonly used by people who suffer from arthritis. 

Acts as Analgesic

If you suffer from chronic pain, or have recently experienced a surgery or injury, use of this oil is recommended in moderate amounts. Kukui nut oil is also a popular choice for burn relief, as it can quickly inhibit pain receptors and numb inflamed areas. 

Boosts Immune System

With rich amounts of vitamin E and vitamin C, this oil is packed with antioxidants and immune-boosting potential. Your skin is exposed to countless pathogens and irritants every day, but if you regularly apply kukui nut oil, particularly to the hands and face, you can give your skin – the body’s largest organ – an advantage when it comes to fighting infections. 

Side Effects of Kukui Nut Oil

There are few reported side effects of kukui nut oil, but some people report skin irritation and stomach upset, often when the oil is used in large quantities. The oil can also have negative side effects if it has surpassed its shelf life. For the vast majority of people, this oil has nothing but positive effects on the body.

  • Stomach Issues – Kukui oil may be versatile and packed with nutrients, but it is also extremely susceptible to heat. Although kukui oil is rarely consumed internally, it is not generally considered toxic, but if the oil has already passed its shelf life, or has been exposed to excess heat, it can cause stomach upset, nausea, diarrhea and other unpleasant gastrointestinal side effects.
  • Skin inflammation – As with any potent natural oil, kukui nut oil can cause inflammation on the skin, particularly for people with sensitive skin, or those who have an allergy to the kukui nut tree. In order to avoid this, apply a small amount of this oil to a patch of skin and wait a few hours to see if any redness or itching appears before putting it on a larger area of your body.
