Hello,

I have not used skin biology products since 2010, and I intend to start again. I have an unopened Protect and Restore delivered 2010. Also I have an unopened emu oil (sample) also from this year, and some other unopened samples.

What is the shelf life of these products? I don't want to risk using product after the expiration date.

They have been in the refrigerator all the time exept maybe a few months after i received it (not sure).

So can I use any of the?

Thanks
Kriss

The copper peptides last a very long time but may develop smell from peptide breakdown. But they still work.

The Emu Oil is more fragile. If it smells, then do not use it.
