Sunscreens can’t stop skin cancer, says report

SUNSCREEN products may not do enough to prevent skin cancer, researchers have warned.

Scientists from a British medical research charity found that ultraviolent A (UVA) light still penetrated the skin even when sunscreen lotions were used in the recommended dosage.

UVA light causes the release of free radicals, which damage DNA and can in turn lead to malignant melanoma, the most aggressive form of skin cancer. Around 90% of skin cancers are caused by the sun’s UV rays, so the disease is largely preventable.
