Sunscreen Expiration Date: Why Should You Not Use Sunscreen From The Previous Year?

Sunscreen Expiration Date: Protective filters degrade over time, and using expired sunscreen means a lack of adequate protection against the sun’s harmful rays.

It has happened to many of us that when we are going to swim or take a dip in the sea or outdoor pool for the first time after the weather warms up, we look for our sunscreen cream and lotion, and maybe at the last moment, we use the same sunscreen that we used last year. Our swimming bag is left, let’s take it with us and rest assured that we are protecting our skin from UV rays.

Sunscreen Expiration Date, But has the sunscreen left over from the previous year not expired and still retains its protective properties?

What is certain is that sunscreen, like other cosmetic products, has an expiration date that indicates that the product can be used for several months after opening. Normally, sunscreen can be used for up to 36 months after production if it is not opened, and after opening, it usually has a date between six and 12 months.

You may wonder what happens to sunscreen after its expiration date. This is an important question. According to the stylist website, expired sunscreen actually no longer provides the necessary protection and its protective filters degrade over time. In this way, using an expired sunscreen means a lack of adequate protection against the harmful rays of the sun, and it causes you to get sunburn and other side effects while you think you can easily go under the sun or swim with that sunscreen. Protect yourself from the ultraviolet rays of the sun.

Sunscreen Expiration Date, It should also be noted that the passage of time is not the only factor that destroys the effectiveness of a sunscreen. If your sunscreen is exposed to heat and sunlight, its protective factors will be destroyed over time. For this reason, it is recommended to keep the sunscreen in a cool and dark place.
