Where do you find the expiration date on Banana Boat products?

Banana Boat states on their website that their sunscreens have a shelf life of 3 years. However, this can be affected by improper storage such as high heat or direct sunlight. To check the expiration date on Banana Boat products, look on the bottom or side of the bottle. There should be a date code printed in the form of a four-digit number, such as 1975. The first two digits represent the year (2021) and the last two digits represent the week of the year (21). So in this example, the product would expire in the 21st week of 2021.
