The sunscreen is effective for 3 years
If you want to use the sunscreen you bought last summer, especially since its bottle is still half full, don’t worry because you can still use it to protect the skin without any potential damage. According to the American Academy of Dermatology, the Food and Drug Administration requires sunscreen makers to ensure that their products remain effective for 3 years. But if you find that the sunscreen has changed its color and smell, and its texture has become inconsistent, do not hesitate to get rid of it because it is definitely expired. The most noticeable signs of an expiring sunscreen are its lumpy, chunky or watery texture, yellow color and strange smell.
The most prominent side effects of using expired sunscreen on the skin

The chemicals in sunscreen degrade over time and by high heat and sunlight, so using expired sunscreen makes your skin vulnerable to burns in the short term, and to skin cancer and skin aging in the long term, because it loses its effectiveness and is no longer able to protect your skin from damage Sun rays. But other than that, expired sunscreen does not cause any harm to the skin or cause any side effects on the skin.
