Tamanu oil has been used for decades as a medicinal salve thanks to its anti-inflammatory, antibacterial and wound healing properties. Today, beauty brands are catching on to the magical benefits this ancient cure-all and adding it to skin-care formulas, from acne scar relievers to hydrating body lotions.
Tamanu oil comes from the seed of the tamanu tree, which “originates from the Pacific Islands and is often considered a ‘sacred’ tree, especially in Tahiti where it is protected and can only be used to build temples,” says Shikohin director of research and development Philippe Dumont. He notes that tamanu oil has long been a remedy for skin concerns among Tahitians due to its calming and healing properties as well as its analgesic and antibacterial effects.
“The tradition is to cover any newborn baby with tamanu oil to ensure total protection. It’s used against sunburn, infected wounds, mosquito bites, scars (even acne scars) and coral cuts for surfers. It’s still used in general hospitals there to treat severe burn patients,” says Elrick. It was even a key remedy for leprosy until the mid-1950s, he notes.
Formulators have been folding tamanu oil into skin-care concoctions here and there for a while, but lately, we’ve noticed tamanu oil popping up on more ingredient lists and social media stories, so we asked experts to give us the need-to-know background on the trending oil.

What is tamanu oil?
Tamanu oil is dark green to brown, semi-viscous and has a nutty odor, says cosmetic chemist Ginger King, and it has found its way into more and more mainstream skin care recently. “This oil is rich in fatty acids, antioxidants and anti-inflammatory compounds and has been traditionally used for its skin-care and medicinal properties to promote skin healing, reduce inflammation and moisturize the skin,” says founder of Byoma and Tan Luxe Marc Erlick.
“From a very personal perspective, I have been formulating and developing products for over 25 years, and tamanu oil is definitely my favorite active ingredient,” says Dumont. “There is always a small bottle of it in my travel bag wherever I go.”
What are the benefits of tamanu oil for skin?
“Tamanu oil is a versatile, natural oil that can benefit various skin types and conditions, from dry and sensitive skin to acne-prone and aging skin,” says Elrick. The experts shared some of the most notable benefits of the trending oil.
It’s rich in fatty acids and antioxidants
“Fatty acids are essential to maintaining a healthy skin barrier. These fatty acids that make up tamanu oil assist with maintaining skin structure and elasticity,” says NUDESKIN skin director Dr. Ally Frankel. The fatty acids can also help combat acne and UV damage, she adds.
Linoleic acid, one of the components in tamanu oil, boasts impressive antioxidant properties. “Linoleic acid is an omega-6 fatty acid and reinforces the skin’s barrier and has also been proven to fight free radical damage,” says Dr. Frankel.
It’s hydrating
According to Elrick, “The most notable benefits of tamanu oil are its moisturizing and restoring properties” since it’s deeply moisturizing and helps replenish skin. Dr. Frankel explains that tamanu oil “adds moisture to the skin by locking in water and reinforcing our skin’s barrier.”
It’s anti-inflammatory
“Tamanu oil has been proven to be one of the safest and most powerful topical solutions as an anti-inflammatory (with no risk of allergies), ideal for treating skin reactions,” says Dumont. Alpha-linolenic acid, found in both tamanu oil and flaxseed oil, is known to be anti-inflammatory and even helps protect against heart disease when consumed, says Dr. Frankel. King notes that the anti-inflammatory benefits come in handy for healing skin and can often be found in shaving and after-sun products.
It can improve wounds, wrinkles, scars and stretch marks
“Due to its reinforcement of the skin barrier protecting the skin from UV, pollutants and bacteria, it is also said to be anti-aging and skin-healing,” says Dr. Frankel. Studies have shown that it has great regenerating properties as it accelerates keratinocyte wound healing, says Dumont. “Thanks to that, it has a great anti-wrinkle effect and is very effective in treating recent scars and stretch marks.”
