Keeping foundations long past expiration date?

Would you keep a foundation years past it’s expiration date/the months on the bottle? Dior Backstage, 2 shades of NARS Sheer Glow, 2 shades of Fenty Eaze Drop and 2 shades of Kosas Tinted face oil. Most of these I bought about 2-3 years ago. . . I found a stash of foundation I bought 3 years ago and tried a handful of times (literally less than 5 times) but then moved about 3 months later and misplaced it in the moving boxes. I just found out it was at my parents house in their storage room with some my other stuff. Would you still keep them? The Dior separated in the bottle but was good but when I shook it.
