Does anyone know the shelf life of Estee Lauder’s Advanced Night Repair serum?
Approximately 2 years from manufacture date as long as it’s unopened. If opened, then it’s good for about 6 months…after that, you should toss it in case there’s any bacterial growth. This is the official word from Estee Lauder.
To see when your product was manufactured (you can do this for all Estee Lauder Companies products) there’s a 3 digit batch number on the box or on the product itself. An example of a batch number would be CA5. The last digit indicates the year the product was manufactured, in the example I gave it means 2005. If unopened, the product would be good until 2007.
The only exception to this is if your product has a funny texture or strange smell, then it’s time to just throw it away completely since it’s gone bad.
Hope this helps a bit.
