Missing Expiration Date
I've used this sunscreen for years, and all bottles have an expiration date on the bottom; these did not have an expiration date stamped anywhere.

Fun in the sun!
Sunscreen smells great and goes on smoothly! No streaks very comfortable to wear! Not oily or greasy like some of the other brands.
