Why must we pay attention to the expiration date?
How to Properly Understand Product Shelf Life and Its Labeling
Each of us has encountered the term "expiration date" when shopping for food, cosmetics, or medicines. Although this label seems straightforward, it actually encompasses a range of factors that affect the quality and safety of products. In this article, we'll explore the meaning of an expiration date, how it differs from other shelf life labels, and why we should pay attention to it not only when shopping but also when storing and consuming the products themselves.
What Exactly Does Expiration Date Mean?
An expiration date is a term that indicates the final date by which a product should be consumed to maintain its quality and effectiveness. It's not just a warning that the product becomes unusable after this date, but also assurance that by adhering to this term, we will get the product in its optimal condition.

For instance, with food, it means the food should retain its taste, texture, and nutritional value until the specified date. After the expiration date, the food may not be immediately dangerous, but its quality may gradually decline. Similarly, with cosmetics, the expiration date is an important indicator of when the product ceases to be safe and effective. Medicines can also lose their therapeutic effectiveness after expiration, which can be very dangerous from a health risk perspective.
Expiration Labeling and Its Various Forms
In addition to the expiration date itself, there are other labels related to the shelf life of products. These include "best before date" and "use by date." These labels have different meanings, so it's important to understand them.
The best before date indicates the period during which the product will retain its quality if stored properly. After this date, the product may still be safe to consume but may gradually lose flavor, color, or nutritional values. Typical examples include dried foods, pasta, rice, or canned goods. For these products, it's common that they remain safe to consume even weeks after the best before date has passed.
On the other hand, the "use by" label is found mainly on fresh foods such as dairy products, meat, or fish. This food must be consumed before the specified date because after this date, it may spoil, and consumption could be dangerous to our health. For these products, strict adherence to storage conditions, such as keeping them cold, is essential.

Why Should We Take the Expiration Date Seriously?
Although it may seem that the expiration date is merely a guideline, it is crucial to take this information seriously. When purchasing products close to their expiration date, we should ask ourselves several questions: How quickly will I consume this product? Do I have the right conditions to store it? Is it possible that its quality will decrease before the expiration date?
Let's take an example. Cosmetics, for instance, can change their consistency, smell, or even cause skin irritation after the expiration date. Products containing active ingredients, such as sunscreens or anti-aging products, may lose their effectiveness, meaning they will not fully perform their function.

With medicines, the situation is even more serious. After the expiration date, some medications can lose their efficacy, while others may start to produce unwanted substances that could be dangerous to the body. It's always important to check medications before use and, in case of uncertainty, it is better to replace them with new ones.
Factors Affecting Shelf Life
One of the important aspects affecting the shelf life of products is the conditions in which the product is stored. Even if the packaging shows an expiration date, improper storage can significantly shorten this term. For instance, foods stored in a warm place that should be kept cold may lose their freshness long before the stated date. Similarly, cosmetic products exposed to direct sunlight may degrade faster than indicated on the packaging.
The packaging of a product also plays a crucial role. For some products, such as vacuum-packed foods, shelf life can be significantly extended by minimizing air access, while open packaging leads to quicker expiration. Therefore, it is always important to not only monitor the expiration date but also carefully read instructions regarding proper storage.

Not Only for Consumers but Also for Manufacturers
Expiration labeling is important not only for consumers but also for manufacturers, who protect themselves from legal consequences this way. If a product has passed inspection and its expiration date is set, it is a certainty for the manufacturer that if the product is stored and used correctly by this date, it will not pose a threat to consumer health. Manufacturers also often test their products under various conditions to determine the optimal period during which the product retains its properties.
The expiration date and various forms of expiration labeling are important factors that protect our health and ensure product quality. Whether it is food, cosmetics, or medicines, it is important to pay attention not only to the stated dates but also to storage conditions and the quality of the product when using it. The expiration date not only protects us but also helps us understand when a product reaches its peak and when we should replace it.
