Can I Use Oil As Natural Sunscreen? (2024)

The benefits ofcoconut oil and other plant oils are seemingly endless when you’re trying to live naturally. Some studies have even shown that certainoils, including olive and coconut oil,can protectagainst sun damage. So in the era of DIY, why shouldn’t you use just oil as natural sunscreen? Here’show we see it.

Oils Often HaveLow SPF Values

Oils from coconuts, almonds and even lavender have been shown to offer a natural SPF. In other words, they absorb a percentage of the sun’s radiation andprevent some of the damage it might cause. Because of this, some naturalists claim you can slather on coconut oil in preparation for a day in the sun. But according to recommendations from health organizations, theSPF levels of most oils aren’t high enough to adequately protect against harmful UV radiation.ⁱ

For reference, here are some of the higher SPF values of oils according to a particular study:

• Coconut Oil: 8
• Olive Oil: 8
• Peppermint Oil: 7
• Lavender Oil: 6
• Almond Oil: 5

This might seem pretty good for natural oils—and it is!—but it isn’t enough to adequately protect youduring sun exposure.In fact, at SPF 8, coconut oil and olive oil only absorb about20% of UV rays!ⁱⁱ

Because products with low SPF provide little coverage, the FDAⁱⁱⁱ and EWG^iv recommend using sunscreen with a minimum SPF of 15. (TheAmerican Cancer Societyand theAmerican Academy of Dermatologygo even further. They recommend sunscreen with an SPF rating of at least 30!) The FDA even requires productsbelow SPF 15 tocontain a warningstatingthey have not been shown to prevent skin cancer or early skin aging. Since many oils fall well below that number, using just oilas natural sunscreen won’t provide the protection you really need.

The SPF of Oils CanBe Inconsistent

Without performing a lab test, there isn’t a good way to knowa product’sactual SPF value.For this reason, FDA regulations require the SPF level of every batch of marketed sunscreen to be tested. However, since natural oils aren’t marketed as sunscreen, they don’t go through that testing.

Even with higher SPF oils, like wheat germ oil, it’s hard to knowhow much protection you’re actually getting. The oilquality canvary between brands and even batches. So while some sources quote specific SPF values for oils, others list wide ranges. Coconut oil, for example, is sometimes said to range between 2 and 8!That’s a big margin of error.

Another study identifieseven more factors that can change an oil’s SPF value. For starters, perspiration and water can easily dilute the oil concentration. Additionally, an oil’s interaction with other substances—even with the skin—can impact its ability to absorb UV rays. All of this makes using oil as natural sunscreen a relatively unreliable mode of protection.

Consider Both UVA and UVB Coverage

According to EWG, an SPF value only signals a product’s ability to protect against UVB rays. That means harmful UVA rays, which penetrate deep into the skin and cause DNA damage and premature aging, aresometimes not accounted for.

This is a problem because UVA rays make up a huge portion of our sun exposure! While our atmosphere absorbs approximately 90% of UVB rays, damage to the ozone layer prevents it from absorbing hardly any UVA rays.^v For this reason, there are approximately 500 times more UVA rays reaching the earth’s surface than UVB.^vi We think that warrants protection!

Experts now recommend products with broad-spectrum coverage, meaning products that protect against both UVA and UVB rays. However, since testing on natural oilsin this areais limited, we can’t know if they offer any protection against UVA rays. In fact, the few available studieson oils’ ability to absorb UV rays only experimented in the UVB range.

Red raspberry seed oil provides a great example. While it’s said to have an SPF rating as high as titanium dioxide’s, it has not been shown to protect against UVA rays. We pair titaniumwith UVA-blocking zinc for safe, broad spectrum coverage. However, there haven’t beenany studies showing that oils can provide the same protection.

Using Oil as Natural Sunscreen Alone Is an Inadequate Means of UV Protection

Everybody loves luxurious ingredients like coconut oil and almond oil, and for good reason! Theseingredientsoffer wonderful skin benefits and offer antibacterial properties. Still, results from the few studies available show that using oil as natural sunscreen doesn’t meet health professionals’ recommendations for adequate sun protection.

At Goddess Garden, we understand wanting to do things as naturally as possible. That’s why we’ve created sunscreen formulas with gentle minerals and nourishing botanical ingredients.In fact, many of our sunscreen formulas contain coconut oil and others said to provide SPF. They nourish the skin and add to thetexture and overall user experience of our sunscreens. But we’ll leave the heavy lifting of UV ray protection to titanium and zinc!
