The importance of skin protection can perhaps never be emphasized enough, especially during the sunny months. The harmful effects of UV rays are well known, as they not only contribute to premature skin aging but also increase the risk of developing skin cancer. That is why proper sun protection is essential in summer, and sunscreen is one of our most important tools in this fight. However, it matters whether you use last year's sunscreen!
The Expiration of Sunscreen
It is important to pay attention to the expiration date of every product, and sunscreens are no exception. Expired sunscreens can not only become ineffective but may also contain harmful ingredients. After the expiration date, the compounds in the sunscreen begin to break down, increasing the risk of skin irritation and significantly reducing the effectiveness of protection.
Moreover, chemical reactions may occur in previously safe sunscreens that can trigger allergic reactions or release harmful substances. Therefore, it is especially important to thoroughly check our sun protection products at the beginning of every summer.
Harmful Compounds and Their Effects
Among the potentially appearing chemical substances in expired sunscreens, oxidized active ingredients are often found. These degradation products can form molecules that harm our skin, causing not only allergies but also potentially leading to sunburn. Such sunscreens can leave our skin defenseless against harmful UV rays without us noticing.
Furthermore, if the sunscreen was not stored properly, for example, if left in the sun or in a warm place for a long time, the ingredients may deteriorate faster. This is especially true for natural ingredient sunscreens that do not contain preservatives. Improper storage can therefore accelerate the degradation process even before the expiration date.
How to Check the Condition of Our Sunscreens?
To stay safe, it is advisable to thoroughly examine every sunscreen before the start of summer. The first step is, of course, to check the expiration date, which is indicated on the product packaging. Additionally, if there is any change in the texture, color, or smell of the sunscreen, it is better to discard it.
The condition of sunscreens can also deteriorate if the bottle is damaged or the cap does not close properly, so it is important to always check the packaging. If you have doubts about the product's quality, it is better not to take risks and get a new sunscreen.
What to Do If We Have Used Expired Sunscreen?
If we feel that our skin shows allergic or irritation symptoms after using a sunscreen, it is important to stop using the product immediately. Wash the skin with lukewarm water, and if more severe irritation occurs, it is advisable to consult a dermatologist.
To avoid problems, always keep in mind the storage and usage instructions of sunscreens to properly protect our skin from the harmful effects of the sun in the long term.
