Hi, Trina all of the products that are sold on TheBeautyplace.com are authentic, new and unused. Since we sell Skinceuticals well below their retail price we are not licensed or authorized by Skinceuticals. A lot of skinceutical products do not come with a expiration date, instead they have a shelf life. Some products like the SPF's do come with expiration dates. If you do need a date you could always call our customer service department and they could help you further with that information.
