In summary - if you wish to buy IN DATE CURRENT STOCK only purchase bareMinerals that do not have I.d on the pots or anywhere on the branding. Remember also that BareMinerals contains no additives or preservatives - therefore once opened, the minerals will have a shelf life like any other natural product. There is nothing in it to preserve it. On this basis I suppose you could argue that if an old I.d product has not been opened then you should be safe - however do you really want to risk it? It is your skin after all. As mentioned previously, as these old pots only have a white sticky label sealing the pot this can be easily removed and replaced without the purchasers knowledge. The locking sifter lid does not allow for contamination.
BareMinerals I.d - AVOID as this will be OLD STOCK and OUT OF DATE. This is how the old pot looks:

This is how the new pot looks and is current stock. OK
BareMinerals Original - OK
Hope this helps! I only sell Bare Minerals current stock. I am an authorised stockist of BareMinerals.
