I have a bottle of LiquiNolva in my closet. Had it for about 2 years now. How should I know if it is expired or does it expire?

everything expires but usually you shouldnt take a product if its over 4 years old.
2 years, you should be good in my opinion, depending on where you had kept it of course.
Should still be good.
yeah should be fine as long as it wasn't in direct sunlight or anything.
Nope its just been sitting in my closet in the dark. Thanks for the help!
