Sunscreen label confusion won't be over before summer after all. The government is bowing to industry requests for more time to make clear how much protection their lotions really offer.

The Food and Drug Administration ordered changes to sunscreens last summer but gave their makers a year — until this June — to get revised bottles on the shelf.

The changes aimed to finally distinguish which brands protected against both sunburn-causing ultraviolet B rays and the deeper-penetrating ultraviolet A linked to skin cancer and premature aging. They also couldn't claim to be waterproof or sweatproof, only water- or sweat-resistant — so that people know sunscreens have to be reapplied frequently.

But sunscreen manufacturers said they were having a hard time meeting the deadline.
