How long is the shelf life of Biore sunscreen? Do not use sunscreen that has expired.

The shelf life of skin care products is very important, especially for sunscreen, because whether it has expired determines the effectiveness of the sunscreen. Let’s take a look at the shelf life of Biore sunscreen.

How long is the shelf life of Biore sunscreen

The shelf life of Biore's most classic blue tube is 3 years, and the shelf life of other Biore sunscreens is 5 years, which means that if they are not opened, they can be used within 3/5 years from production. If it has been opened, it needs to be used up within the same year and cannot be saved for use in the next year, because Biore sunscreen is the same as all other sunscreens. If used again in the second year, it will affect the sun protection effect.

How to check the production date of Biore sunscreen

There is a production batch number printed on the top of the Biore sunscreen bottle, and the last four digits are the production date. For example, if the production batch number is T0000454, then you only need to look at the last four digits "0454". The last digit indicates the production year, "4" means 2014, and the first three digits indicate the production date. "045" means the 45th day of 2014, which is February. The same applies to other production batch numbers.
