It’s tempting to reach for something as simple, natural, and seemingly innocuous as coconut oil when thinking about sun protection. After all, coconut oil has all these buzzworthy qualities—moisturizing, antibacterial, and even a bit of a cult following among wellness enthusiasts. But can it really stand in for sunscreen? Let me walk you through why this question deserves more than just a quick yes or no and why slathering coconut oil on your skin as your sole defense against sun damage might be more wishful thinking than smart skincare.
Understanding What Sunscreen Actually Does
Sunscreen isn’t just about keeping your skin comfortable or shiny; it’s your primary shield against ultraviolet (UV) radiation from the sun. This radiation comes in two main types: UVA and UVB. UVB rays are the culprits behind sunburns, while UVA rays sneak under the radar causing deeper skin damage and play a major role in premature aging and skin cancer. The magic happens because sunscreens contain ingredients that either absorb, reflect, or scatter these harmful rays, offering measurable protection. The term SPF (Sun Protection Factor) is what you often see—it tells you how well the sunscreen protects you against UVB rays specifically.
Now, the rub is that most plant-derived oils, including coconut oil, do not reliably block UV radiation in a way that’s equivalent to commercial or mineral sunscreens. Even if coconut oil contains some natural UV-blocking compounds, the level of protection is minimal and far below what dermatologists recommend for safe sun exposure.
Coconut Oil and Its Natural SPF
You might have heard claims that coconut oil has an SPF of around 4 to 8. If you think about it, that’s practically negligible when recommended sunscreen use is SPF 30 or higher. SPF 4 means that the oil lets 25% of UVB radiation reach your skin, compared to higher SPFs that block much more. And keep in mind, these SPF values for coconut oil are not officially verified in controlled scientific testing the way commercial sunscreens are. They often come from small or outdated studies and shouldn’t be considered a reliable standard.
Also, coconut oil’s SPF primarily offers some UVB protection but doesn’t provide significant UVA coverage. UVA rays penetrate much deeper and cause long-term damage, so ignoring them is risky. Most broad-spectrum sunscreens, the ones you should be using, give you defense against both UVA and UVB rays.
What Happens if You Rely on Coconut Oil Alone?
Choosing coconut oil over sunscreen is a bit like trying to shield yourself from a rainstorm with a thin umbrella. Sure, it might reduce the drizzle slightly, but the storm will still soak you. While coconut oil may moisturize your skin beautifully and even reduce inflammation, it won’t stop sunburn or shield your skin cells from the DNA damage UV rays inflict.
DNA damage is where the real danger lies. When UV rays cause mutations in your skin cells, it increases your risk of skin cancers like melanoma, basal cell carcinoma, and squamous cell carcinoma. Study after study has shown that diligent sunscreen use lowers this risk significantly. By contrast, coconut oil offers little to no protection—and worse, because it’s an oil, it could even exacerbate sun damage by attracting heat to your skin.
The Myth of ‘Natural’ Protection
There’s a powerful narrative out there about ditching synthetic chemicals for “natural” products in our skincare. I get it—chemicals sound scary, and our skin is an organ that breathes and absorbs. But natural doesn’t mean safe or sufficient, especially when it comes to UV protection.
To highlight the difference, think about zinc oxide and titanium dioxide—ingredients in mineral sunscreens. These are natural minerals that sit on the surface of the skin and physically block UV rays. They’re widely regarded as safe, with decades of research backing their use. Coconut oil doesn’t work that way; it absorbs into the skin but can’t reflect or effectively absorb UV radiation at meaningful levels.
Complementary Benefits of Coconut Oil in Sun Care
That said, coconut oil shouldn’t be dismissed altogether. It’s a fantastic moisturizer, assists with skin barrier repair, and has anti-inflammatory properties. After a day in the sun, applying coconut oil to soothed, cleansed skin can help lock in moisture and reduce peeling or dryness. It can also work as a carrier oil for essential oils known for soothing properties, like lavender.
However, pre-sun coconut oil application alone is akin to putting on a light jacket to fend off a blizzard. It doesn’t replace the robust defense your skin needs from UVA and UVB damage.
Is There a Safe Way to Use Coconut Oil and Sunscreen Together?
If you’re a fan of coconut oil and want to incorporate it, apply your trusted broad-spectrum sunscreen first—let it absorb and dry—and then layer the coconut oil on top to boost softness and hydration. This strategy lets you keep the science-backed protection while still indulging your skin with coconut oil’s cosmetic benefits.
But layering cannabis oil (another natural product sometimes touted for skincare) or other oils directly under your sunscreen can sometimes reduce sunscreen efficacy, so the order and testing matter. Stick to well-established application routines for sun safety.
What Do Dermatologists Say?
Most dermatologists agree that the best way to prevent sun damage is by using a broad-spectrum sunscreen with SPF 30 or higher, applied generously and reapplied every two hours or after swimming and sweating. They also emphasize physical barriers like hats, sunglasses, and seeking shade during peak sunlight hours.
While coconut oil doesn’t make the list of recommended sun protection methods, dermatologists recognize its value in skin hydration and post-sun care but always in combination with proper sunblock use.

Final Thoughts on Coconut Oil and Sun Protection
Coconut oil feels like an all-natural wonder, but when it comes to sunscreen, it simply isn’t enough. If you want to protect your skin against the sun’s harmful rays—and keep it healthy, youthful, and cancer-free—sunscreen isn’t negotiable.
The allure of ‘natural’ alternatives is hard to resist, especially with the endless glow stories and DIY health tips flooding the Internet. But this is one area where relying on tested—and tested means rigorously tested—products can literally be a matter of life and death.
If you enjoy using coconut oil, use it where it shines: as a nourishing moisturizer after you’ve protected yourself properly with sunscreen. Think of it as a buddy to sun care, not the main act.
