Neutrogena sunscreen can be stored for three years if unopened

​What is the shelf life of Neutrogena sunscreen? Neutrogena sunscreen has good reviews, so many girls have bought it. Then everyone discovered that Neutrogena sunscreen did not seem to have an obvious shelf life. So how do you know if your Neutrogena sunscreen has expired? Let's take a look at it in detail below.

Neutrogena sunscreen shelf life

The shelf life of Neutrogena sunscreen is generally three years, but it is recommended that Neutrogena sunscreen be used up within the same year after opening. Because after opening Neutrogena sunscreen, the number of times it comes into contact with air will increase with each use, which will accelerate the loss of sunscreen ingredients. If you save Neutrogena sunscreen for use until the following year, it will no longer have any sun protection effect.

How to check the shelf life of Neutrogena sunscreen

The shelf life of Neutrogena sunscreen is usually marked at the end of the bottle, and the reading method is the same as in China. For example, 20170525 means May 25, 2017. However, it should be noted that before looking at the date on the end of the Neutrogena sunscreen bottle, you need to first check the outer packaging to see whether the date on the end of the bottle is the production date or the expiration date, so as to avoid misreading the expiration date as the production date, which may cause skin discomfort.

Can I still use Neutrogena sunscreen after it expires?

Neutrogena sunscreen cannot be used after it expires, because the sunscreen ingredients in it have completely lost their effectiveness and will not have any effect when used again. Moreover, the texture of Neutrogena sunscreen will change after it expires. If you use it again, it may cause allergic reactions such as redness and fever on your skin. Therefore, never use Neutrogena sunscreen after it expires.

Is Neutrogena a physical sunscreen?

No, it is a chemical sunscreen. It does not contain physical sunscreens such as titanium dioxide or zinc oxide. It contains denatured alcohol, so it is refreshing to use. In addition, it is not recommended to use sprays containing physical sunscreens. Although sprays are more convenient to use, physical sunscreens such as titanium dioxide or zinc oxide are easily absorbed into the body when using sprays. These two ingredients are harmful to the body, so pay attention to these ingredients when choosing a sunscreen spray.
