Any cosmetic product, whether serum, cream or patch, has two expiration dates – before and after opening. The first is usually stated on the box after the words “Expiration date…”, “Expiration date…” or EXP. The latter is indicated by an open jar with the number of months inside – this is how long the product can be used after opening. There are products such as eyeshadow palettes, flat pencils or highlighters that can last more than two years. There are those that live almost forever – perfumes. And there are cosmetics that, as they say, are perishable. You cannot relax with it, otherwise you risk developing allergies or irritation.
natural cosmetics
Shelf life: 3-6 months
Remember one rule: the more natural the composition, the shorter the product is stored. This applies not only to food but also to cosmetics. This is because natural cosmetics do not contain strong synthetic preservatives. These types of products usually use natural preservatives that do not have the same strong effect as chemical substances. Natural cosmetics have a shorter shelf life after opening – up to 3-6 months. That’s why products labeled as natural are often sold in small packages – so that the person has the opportunity to use the product even in a short time. After the expiration date, natural cosmetics should be thrown away because they not only become ineffective, but can also cause allergies.
Mascara
Shelf life: 3-6 months

Among the perishable products of decorative cosmetics, mascara can be highlighted. First of all, the eyes are one of the most sensitive areas, so it is easy to get infection or inflammation. Secondly, mascara is constantly in contact with air and bacteria constantly get onto the brush. For this reason, the shelf life of mascara is shorter than many other decorative products. If you dye your eyelashes every day, it would be better to change the product every three months. If mascara is not visible too often in makeup, it can be stored for a maximum of six months.
Cream in a jar
Shelf life: 3-6 months
As much as we like the look of heavy glass jars with cream, they are not that comfortable to use. The product is constantly in contact with the air and our fingers (unless you are one of the rare people who still use special spatulas). Products are better stored in tubes, dispenser or pump packaging. Therefore, if you want to extend the life of your cream, pay attention to its packaging.
eye patches
Shelf life: 3-6 months

Our patches, which have been sitting on the shelf in the bathroom for a year, are now stretched… But yes, their shelf life is not actually that infinite. After turning on the disc, it decreases sharply. Patches in closed packaging can be stored for up to three years. But in the open air – 3 months at room temperature, 6 months in a dark cool place. Since the area around the eyes is the most delicate and sensitive skin that you need to be careful with, we still recommend trying to remember the first time you took the patches out of the jar.
liquid eyeliner
Shelf life: 3-6 months
Since eyeliner is applied close to the eye area or directly to the lash line, like mascara, it should be changed every 3-6 months, depending on the frequency of use. By the way, eyeliner in pencil format lasts longer than liquid eyeliner. The fact is that products containing water are the most perishable, as water is a suitable environment for the spread of bacteria and germs.
We talked more about the expiration date of cosmetics and when you should throw away the product before it expires.
