Summer is here, and people who are afraid of getting tanned will take great efforts in sun protection. As a result, more and more sunscreens are now available on the market.

How to check the date of Japan Biore sunscreen

There is a production batch number on the top of the Biore sunscreen bottle, and the last four digits are the production date. You can also directly look at the last four digits of the number. The last digit represents the production year, and the first three digits represent the production date. For the classic blue-tube Biore sunscreen, its shelf life is three years. For products that have been opened and used, please note that the shelf life is no more than one and a half years. After that, they will lose their effectiveness.

Why does the shelf life of Biore sunscreen become shorter after opening?

In fact, the reason why the shelf life of sunscreen becomes shorter after opening is very simple. After opening, it will react with the oxygen in the air and most of it will have been oxidized. Over time, it will no longer be able to protect against the sun. The sun protection effect will be greatly reduced and it may even breed bacteria and cause deterioration. Therefore, after opening and use, the shelf life will be shortened.

Can Biore sunscreen be used after it expires?

It is not recommended to use it, especially on the face, because the face is a very sensitive area. But if you don’t want to waste it, in fact, expired Biore sunscreen can be used on the body, such as the legs and hands, or it can be used to polish leather shoes in daily life.

Do I need to remove makeup after using Biore sunscreen?

I believe that many people feel too lazy to remove makeup after applying sunscreen because they think that sunscreen is used to protect their skin. In fact, no matter what kind of sunscreen you use, you need to remove it after use. It doesn’t take long, but it can help maintain your skin.
