As the weather warms, many of us would prefer to look like we passed our winter days lounging by the pool instead of hunched before a computer screen or lab bench. But soaking up the rays to acquire a so-called “base tan” does not fool the sun or a tanning bed. Simply put, the benefits of being sun-kissed are not even skin-deep.
Scientists came to this conclusion after studying the tanned buttocks of dozens of volunteers. In study after study they have found that a base tan affords almost no protection against future ultraviolet exposure. In fact, it actually puts otherwise pale people at risk of developing skin cancers.
