I Have These Equate Whitening Strips That Expired In November 2007. Are They Safe To Use? Do They Still Whiten?
--------------------
I'm sure they are safe, they just might not be as effective. Overtime the active ingredients begin to deteriorate and the manufacturer places an expiration date on it to ensure a product that isn't working as well as it could be aren't on the shelves cause it's not good for business.
