I think if it is left unopened then it would be fine; but once the air gets to any oil, it will go bad if not used. I ordered a JM TSV last year and just threw out a bout 1/3 of a small bottle of light argan oil as it smelled bad. So wasted some $ by not using it up. If you bought a huge bottle then use it everywhere so you aren't just wasting $$. That's why these huge bottles of stuff at such a great price, really aren't a good value, if they are not used. Am learning that the hard way, as I am throwing out alot of product that has turned bad.
