Every summer, the days get longer and the temperatures rise. And every summer, social media posts claiming that sunscreen causes cancer, or is a scam, start spreading again.
Some of these posts point to real scientific research but leave out important context. That twists what the study actually found.
One example is a 2023 study that found people who used sunscreen more often were also more likely to develop melanoma, a dangerous type of skin cancer. That sounds scary, but it doesn't mean sunscreen caused the cancer. When two things happen together, one isn't necessarily causing the other.
The researchers point to something called the "sunscreen paradox." People who use sunscreen a lot may also spend more time in strong sunlight. They may also not put on enough sunscreen or reapply it often enough. So the extra sun exposure, not the sunscreen, is likely what raises their risk.
Sun exposure is a balancing act. A little sunshine helps your body make vitamin D, which you need. Too much can damage the DNA in your skin cells. Sunscreen cuts down on the ultraviolet (UV) rays that reach your skin. These are the invisible rays from the sun that cause sunburns. Experts recommend using sunscreen along with shade and protective clothing. It takes a little more planning before a beach day, but it's worth it.
