Can I still use sunscreen after opening it for a year?

It is recommended not to use it. The reason why sunscreen has a sun protection effect is that it contains sunscreen ingredients such as zinc oxide and titanium dioxide. Although these ingredients will not expire and deteriorate over time, other ingredients in sunscreen will deteriorate due to high temperature, contact with air, improper storage, etc., especially sunscreen that has been opened and has been opened for one year. It is best not to use it again.

What can you do with a sunscreen that has been opened for a year?

Sunscreen that has been opened for a year may not only have no sun protection effect, but may also cause skin allergies. The skin on the face is relatively delicate, so it should not be used anymore. However, if the sunscreen is well preserved, you can use it to apply on your arms and legs one year after opening. Although the sun protection effect may not be great, it should still be some, provided that it is a well preserved sunscreen, that is, its texture and state have not changed.

If the sunscreen has been opened for one year, do not use it on your face, but it can be used on other parts of the skin.
