Many cosmetic products contain marula oil. The oil has amino acids, fatty acids, and antioxidants that may benefit the hair, skin, and nails.
Marula oil comes from the marula fruit tree (Sclerocarya birrea), which is found in southern Africa. The oil primarily comes from the kernels of the tree. It is pale yellow and has a slightly nutty scent.
Though marula oil is becoming a more popular ingredient in cosmetic products, it has been used by people living in southern African regions for thousands of years as a food, medicinal treatment, and moisturizer, as well as in traditional rituals.
This article discusses marula oil in more detail, including its benefits, how to use it, and potential side effects. The article also explores the differences between marula oil and argan oil.
- Amino acids: The oil contains amino acids, such as L-arginine, additional

- Fatty acids: Marula oil also contains fatty acids, according to
2015 research. These include oleic acid, palmitic acid, linoleic acid, palmitoleic acid, and stearic acid. Fatty acids are a common ingredientin moisturizers.
- Antioxidants: Various parts of the marula fruit tree contain antioxidants. These substances help slow damage to cells, including skin cells.
The oil may have potential benefits for parts of the body, including:
- Hair: Marula oil may help to strengthen and moisturize dry, brittle, or damaged hair, according to
2018 research. However, further conclusive research into the effect of marula oil on hair is necessary.
- Skin: The oil has hydrating and moisturizing properties on very dry skin, the same 2018 research says. The skin absorbs it well, so it may act quickly.
- Nails: A person may use marula oil to moisturize the nail beds and cuticles. This may help reduce hangnails and cracked skin around the nails. However, research into the effects of marula oil on nails is needed.
It is important to note that marula oil has not been widely studied. Further research is necessary to confirm all of its properties and how they may benefit a person’s health and well-being.
Current research does not indicate side effects associated with using marula oil. A 2015 study suggested that marula oil was not irritating when applied to the skin.
However, scientific research into the side effects of marula oil is lacking. So, short- and long-term side effects are possible when using this oil.
People should consider performing a patch test before using marula oil on their face or all over their skin. A patch test can help determine if marula oil or products containing marula oil may cause irritation or an allergic reaction.
