Can Watermelon Juice Protect You From the Sun?

You Should Know: The latest anti-sunscreen trend involves a summertime staple: watermelon. A viral video circulating on social media shows a wellness influencer claiming drinking watermelon juice serves as a “natural sunscreen.” Dermatologists and other medical experts, however, disagree. 

Going Deeper: The claim stems from the fact that watermelon contains high levels of lycopene, a phytochemical that’s also found in tomatoes, grapefruit, guava (and is responsible for their red and pink flesh). Lycopene does have antioxidant properties that can neutralize free radicals caused by UV exposure. Some research has also found that lycopene can lessen skin redness and reactions to UV rays.

Takeaway: Watermelon juice doesn’t actually protect the skin from UV rays — or from the skin cancer that could follow. Consuming lycopene-rich foods can improve skin health overall, but it’s not a replacement for sunscreen. There’s also no solid research that supports claims that sunscreen is harmful. 

Bottom Line: Whether you eat it, drink it, or rub it on your skin, watermelon will not protect you from the sun’s UV rays. The best ways to prevent sun damage are to use broad-spectrum sunscreen (at least SPF 30), wear protective clothing, and avoid direct sun during peak hours instead.
