Summer is here, and it’s time to protect yourself from the sun. So how long is the shelf life of a sunscreen stick? How long can a sunscreen stick be used after opening?

What is the shelf life of sunscreen sticks?

The shelf life of an unopened sunscreen stick is generally three years, but the shelf life of a sunscreen stick after opening will generally be shortened. Because after the sunscreen stick is opened, the more times it is used, the more times it comes into contact with the air, which will affect it and accelerate the loss of its effective ingredients.

How long can you use a sunscreen stick after opening it?

It is recommended to use up the sunscreen stick within the same year after opening it, because the sunscreen stick usually needs to be rotated to a certain height of the paste during use, so the paste will often come into contact with the air and may even be contaminated with bacteria that are invisible to the naked eye during use. Sunscreen sticks are recycled, so the effective ingredients in them will definitely be affected. Therefore, it is recommended that the sunscreen stick should be used up within the same year after opening, and not saved for use next year.

Okay, now you know the shelf life of sunscreen sticks.
