Can Drinking Watermelon Juice Protect Your Skin From the Sun?

Every summer, there’s a new wellness claim that promises to make life a little easier. This year, it’s watermelon juice. According to social media, drinking it can help protect your skin from the sun thanks to its high lycopene content.

It’s true that watermelon is one of the best dietary sources of lycopene, an antioxidant also found in tomatoes, pink grapefruit, and guava. But does that mean you can swap your sunscreen for a glass of juice?

Not even close.

Where the Idea Comes From

Like many viral wellness trends, this one starts with a real piece of science.

Lycopene has been studied for years because of its antioxidant properties. Research suggests it may help reduce some of the oxidative stress that happens after UV exposure, and people who regularly eat lycopene-rich foods may experience modest benefits over time.

That’s where the science ends—and where social media starts filling in the blanks.

While lycopene may help support your body’s natural defenses against oxidative stress, dermatologists say there’s no evidence that drinking watermelon juice creates anything close to the protection you get from sunscreen.

Why Watermelon Isn’t a Substitute for SPF

The easiest way to think about it is this: sunscreen helps prevent UV rays from damaging your skin in the first place. Antioxidants help your body respond to some of the damage that occurs after exposure.

Those are two very different jobs.

No food or drink provides the kind of measurable UV protection that broad-spectrum sunscreen does, which is why dermatologists continue to recommend sunscreen as your first line of defense against sunburn, premature aging, and skin cancer.

The Best Way to Think About It

That doesn’t mean watermelon has no place in your summer routine.

Watermelon is hydrating, naturally rich in lycopene, and an easy way to eat more fruit during the warmer months. Including antioxidant-rich foods in your diet is a smart choice for your overall health, and they may offer your body some additional support when it comes to managing oxidative stress.

Just don’t think of them as wearable sun protection.

The Bottom Line

If you’re heading outside, enjoy the watermelon—and put on the sunscreen.

The two can absolutely work together, but they aren’t interchangeable. Watermelon supports your overall health. Sunscreen protects your skin from UV damage. Both deserve a place in your summer routine, but only one belongs in your beach bag.
