How long is the shelf life of sunscreen sticks? Many girls are interested in sunscreen sticks, but they are worried that their shelf life is not long enough, so let me introduce to the girls how long the shelf life of sunscreen sticks is. Let's take a look~

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 opening the sunscreen stick, as the number of times it is used increases, the number of times it comes into contact with the air will also increase, and it will be affected by microorganisms and bacteria in the air, accelerating the loss of effective ingredients.

Sunscreen stick shelf life after opening

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 you use up the sunscreen stick within the same year after opening it, and do not save it for use next year.
