While we don't doubt "Crest Whitestrips Advanced Seal" is stated on your foil package, we're not so sure we can give you a definitive answer just based on that detail alone.

The "advanced seal" reference simply refers to the way the strips adhere to your teeth, and has no bearing on how long you wear them (but this property would be more likely to be a characteristic of strips worn for longer durations, either worn 30 or 60 minutes).

"Crest Whitestrips" is obviously their brand name. In years past that term when used alone typically meant their basic/introductory product, which was worn for 30 minutes. But we don't know if your packaging contains other descriptors that would indicate a different product.

The safest bet would be to contact Crest.
