Buy smaller bottles: And use it up each season! or, better yet, stay out of the sun. Really, the loss of potency or protective capability is quite minimal even after one year, but fresh is always going to be better, including the manufacturer's own recommendations. It is still better to use "old" sunscreen than none at all. Just try to limit exposure for any reason, including tanning beds!
