Tamanu Oil: Is Tamanu Oil Good For Yor Breakouts?



What Is Tamanu Oil?

Tamanu oil is a naturally-derived oil that is sourced from the seed of the Calophyllum inophyllum tree, an evergreen native to Southeast Asia. Tamanu oil historically has been used in medicinal practices for hundreds of years. This is due to its mild antibacterial properties and potential to help support wound healing.

These benefits, as well as tamanu oil’s high concentration of fatty acids, antioxidant and potential anti-inflammatory benefits, have made tamanu oil a popular new skincare ingredient.

Tamanu oil comes as a dark green, thick oil that is often described as having a unique nutty, earthy smell. Some people find the scent of tamanu oil offputting, if this is the case it may be best to use products that formulate tamanu oil with other ingredients, in order to reduce the scent but still receive the benefits.

What Are The Benefits of Tamanu Oil?

Tamanu oil is known for its variety in benefits to the skin, such as antibacterial, wound healing and hydrating.



Tamanu oil is a rich source of fatty acids which help to keep the skin hydrated and prevent moisture loss. Tamanu oil is often recommended for dry skin types as the rich, thick oil acts like the skin’s natural barrier reducing the moisture and water loss from the skin to the air. This moisture loss is also known as transepidermal water loss or TEWL.



Tamanu oil has recently been found to have antibacterial properties. Studies have found that tamanu oil’s antibacterial properties are effective against the two most common bacteria that are found in acne, p.acnes and p.granulosum. This along with tamanu’s soothing abilities may make it a great oil to support the treatment of acne.



A compound called calphyllolide is found in tamanu oil, this compound is well-studied for its anti-inflammatory benefits. This may mean that tamanu oil is a potential supporting treatment for inflammatory skin conditions such as eczema, psoriasis and rosacea.


Wound healing

Alongside the soothing properties of tamanu oil, it also may have some wound healing benefits. Studies have suggested that tamanu oil may help to support collagen production and increase the number of glycosaminoglycans or GAGs. GAGs are sugars that are important for the production and maintenance of collagen and elastin. This may make tamanu oil even better for acneic, irritated or compromised skin.



Tamanu oil is also a great source of antioxidants for the skin. Antioxidants help to reduce the effects of free radicals on the skin. Free radicals are produced through a process known as oxidative stress. Oxidative stress often occurs in response to UV exposure, pollution, diet and smoking. The free radicals produced by oxidative stress cause damage to the cells in your body and have been linked to some of the visible signs of aging. Antioxidants help to neutralize this process.

Is Tamanu Oil Comedogenic?

Tamanu oil contains fatty acids that are both comedogenic and non-comedogenic, containing both oleic and linoleic acid. This means that tamanu oil only mildly clogged pores. As tamanu oil has so many benefits for acenic skin it may be useful for some people who experience breakouts or acne, particularly dry skin experiencing acne. However, if you have oily skin that experiences breakouts you may want to test out tamanu oil first and discontinue if congestion occurs.

Does Tamanu Oil Help Support The Skin’s Natural Barrier?

Tamanu oil may help to support the healthy functioning of the skin’s natural barrier. As tamanu oil contains a number of fatty acids, it may help to reduce dryness and decrease the liklihood of water loss. Fatty acids are part of the skin’s natural barrier and help to provide protection and moisture.

Is Tamanu Oil Vegan?

Tamanu Oil is a plant-derived ingredient. As such it is considered a vegan ingredient. However, if you are looking for a vegan product it is best to check the other ingredients in the formulation and ensure that the brand is cruelty-free.

Is Tamanu Oil Safe?

The complexity of any plant-derived ingredient can make it difficult to identify which components of the ingredient are safe and non-irritating. As tamanu is a plant-derived ingredient, this complexity applies. One of the main issues to note is that those with allergies to tree nuts should avoid using tamanu oil as this allergy may be triggered with its use.

The Cosmetic Ingredient Review Expert Panel, a group that is responsible for evaluating the safety of skincare and cosmetic ingredients, has not reviewed the safety of tamanu oil. However, this ingredient is not usually associated with irritation or sensitivity.
