Expiration date of lipstick

Lipstick is an indispensable attribute of decorative cosmetics, which can be found among most young ladies who want to look stylish, fashionable and well-groomed. But, like any other product, makeup has its own period of use, including lipstick.

There are probably a small number of fashionistas who carefully study the packaging in search of this information. Therefore, it is quite a common situation when your favorite cosmetics fail at the most crucial moment, refusing to lay down in an even layer or causing a severe allergic reaction - cheilitis. To avoid possible troubles, you should know about expiration dates and proper storage methods. As for the first parameter, it varies depending on the type and ranges from 24 to 36 months.

Expiration date of lipstick

Many people believe that only food can go bad. In fact, this also happens with decorative cosmetics, be it foundation, mascara, eye shadow or lipstick.Each of these products is a combination of certain chemicals that over time react with air and begin to oxidize. For example, decorative lip makeup products dry out or deteriorate after prolonged contact with the environment.

When purchasing decorative cosmetics, preference should be given to options that have the longest period of use. These products are of high quality and contain natural ingredients and chemical compounds that are safe for the human body.

Closed

In the open and closed states, the storage period is slightly different - this nuance must be taken into account. Of course, in the so-called pristine state the shelf life will be longer than in open condition. According to existing standards for sealed products, the following time frames, measured in months, are established:

1. Liquid lip gloss – 36.
2. Classic lipsticks – 36.
3. Pencil – 24.
4. Tints – 36.
5. Lipstick polish – 36.
6. Matte – 24.
7. Hygienic balms – 36.

As for any other product, GOST standards are established for decorative cosmetics. Lip makeup products are combined into one category - P52342-2005 and 31649-2012. These figures, unfamiliar to many, indicate that manufacturing companies independently set the shelf life of their products, taking into account the formula used and operating conditions:

Standards set by companies, expressed in months:

1. AVON – 24.
2. Oriflame – 24.
3. PUPA – 24.
4. Dior – 1.5.
5. Maybelline – 36.
6. L'Oreal - 36.
7. NYX – 24.

It is important to know: despite the long period of operation in a closed state, manufacturers strongly recommend using decorative products throughout the year.In the future, quality, durability and environmental friendliness will decrease.

Open

After opening the package, it loses its seal, and the products stored inside react with the environment. As a result, the product (under the influence of oxygen contained in the air) begins to oxidize. This leads to cosmetics gradually losing their original properties. According to the standards established by manufacturers, the average lifespan after opening a lipstick package is from 6 months to one year. The product should then be disposed of, otherwise it may cause harm to health.

What determines the shelf life

Before you buy and start using this or that decorative product, you should find out about the established period of operation. When calculating the optimal time frame, cosmetology corporations take into account many nuances. The first of these is the composition and ingredients used to create makeup products. The statement will be absolutely true: the more natural components are included in the chemical formula, the longer the service life will be.

The period is also affected by the form of production. For example, creamy sticks last significantly less than liquid products. But these are not all the main factors influencing the period of use. The following parameters play an important role:

• storage conditions;
• method of application - using an applicator, brush, finger or directly from the tube;
• maintaining personal hygiene - if you let your friends use your cosmetics, she will live much shorter.

Storage rules

Every fashionista should know how to store lip makeup so that it retains its original quality and safety for a long time. There are a number of rules that, if followed, will extend the life of the product:

1. Do not expose the product to direct sunlight.
2. Optimal for storage is a dark, dry place with a temperature not exceeding 25^OWITH.
3. After each use, close the cap tightly.
4. Do not allow lipstick and any liquid to come into contact.
5. Products should not be exposed to temperature changes.

In order not to speed up the process of deterioration, it is advisable to apply lipstick using a brush or applicator in order to avoid direct contact with the epidermis of the lips.

Signs of delay

Frequent contact with oxygen inevitably leads to the appearance and rapid proliferation of various microorganisms, which cause damage to the product: it gradually changes its original appearance, structure, a white coating and foreign odor appear. If the opening time of the tube is not known exactly, the following parameters will help determine the unsuitability of the product:

1. Change in original consistency. The product may crack, spread, or, conversely, become hard. In this case, you should not try to restore the original appearance - you need to get rid of such lipstick immediately, otherwise you can harm your health.
2. Lumps have formed on the surface or drops have appeared.
3. The smell, color scheme, taste have changed.
4. A whitish coating appeared.

Like other products, decorative lip cosmetics have their own shelf life, which every girl needs to know. It is strictly forbidden to use spoiled products - such lipstick should be disposed of immediately.Otherwise, pathogenic organisms will enter the epidermis, which will lead to the development of dermatological diseases.
