hey there BraveXuan,
i've used this product for a few years now, but not regularly so one bottle usually lasts me a year or more. i've never had one go bad on me or stop working, so i'd assume that you can use it for a while. you might want to toss if if it's like more than 2.5 years old, but i doubt it would be bad for your skin if you used it at that point.
