Instead, it should be specified how many minutes this cream is active under water, so that the consumer has real information, said the Food and Drug Administration (FDA).
The regulation will be implemented in this country from next year.
According to the FDA, the new regulations are supported by the most advanced science available and it is expected to reduce confusion about sunscreens.
Under the new guideline only those sunscreens that offer sun protection factor (SPF) of 15 or more may affirm they are of broad spectrum.
Currently, the FDA considers whether to allow the sale of products with an SPF of 70, 80 or 100 because the tests have not proved that they protect more than an SPF of 50.
