According to the Mayo Clinic, "sunscreens are designed to remain stable and at original strength for up to three years."
If your sunscreen does have an expiration date that has expired, do not use it.
If you have sunscreen bottles that you are using from one summer to the next, you are not using enough for aqueduct protection; you can read more about this here. A full ounce (shot glass full) is how much sunscreen should be used at each outing. A sunscreen bottle/tube should only last a few applications, if you are applying it liberally enough. (Dermatologists even say that consumers should worry more about applying enough sunscreen instead of how high the SPF is.)
