Lipstick is the beauty product that every woman has. It allows you to give an attractive look to the lips, as well as care for them. In order for the product to retain its color and properties, you should not only carefully choose it, but also change it to new products in a timely manner. The expiration date of lipstick is described in the article.
Is there a deadline?
Like other cosmetics, lipsticks and lip glosses contain various chemicals. Over time, some are able to enter into chemical reactions with oxygen or oxidize. Therefore, the tool becomes unusable due to drying or deterioration.
Many manufacturers increase the shelf life of lipstick by adding ingredients that are resistant to oxidation. But there are rules in force for this product. Moreover, manufacturers cannot violate them.
What affects him?
The shelf life of lipstick is determined by the composition. If there is a solid basecastor oil, which is resistant to oxidation, then this period increases. The more safe antioxidants are in the product, the longer they last. The same functions are performed by preservatives.
The types of cosmetics also matter: lipsticks last longer than lip glosses. Unopened lipsticks have a longer shelf life. The method of application, storage conditions, and compliance with hygiene rules are also taken into account.
Composition
As the modern beauty industry is actively developing, new lipsticks are constantly being released that have perfect aesthetic properties. Each cosmetic company adds its own substances to this product. But most products have the following components:
- Waxes that come in hard and semi-hard. They are added in an amount of 2 - 13%. They are required to bind other components and maintain hardness. To eliminate dullness, waxes are added to beeswax, which are made from palm leaves, cacti or roses. With their help, cosmetics will be resistant to temperatures, do not smear, retain saturation. All types of wax must be added in a certain ratio. For example, the volume of beeswax is usually no more than 2 - 5%, because it makes the lipstick dull. To add shine, Cadelian wax is used in an amount of 13%. Carnauba wax is used in amounts up to 5%. Some companies use synthetic instead of natural waxes.
- Lanoline. This substance and its derivatives are consideredcomponents that are made from sheep's wool. This substance has disadvantages - an unpleasant taste, smell and high stickiness. Often, lanolin leads to allergies in the form of contact dermatitis. Typically, lipsticks contain about 5% lanolin, and in glosses its content reaches 70%.
- Dyes. Used to give color. Natural dyes used to be vegetable juices, natural herbs, and pigments from insects. Modern cosmetics include chemical dyes from the D&S category. This is a list of dyes that are allowed in pharmacy. Each shade has a personal serial number. The percentage indicates the saturation of the color.
- Oils - synthetic and natural. With their help, varnishes and pigments do not precipitate. Perfume oils are considered solvents for lipstick components and make up to 30% of lipstick volume. Usually sunflower, castor or chamomile oil is used in cosmetics. With these components, lipstick is easier to apply on the lips. Aroma oils are added for the attractiveness of the product, its pleasant aroma and taste. Aroma compositions are fruit aromas and natural esters.
- Pearl additives, such as mica. Added up to 25%.
- Pine rosin. Add up to 4%, for hardness, film-like coating.
- Microspheres. These are small particles that give the product saturation and fat content. They have a positive effect on the skin and include special chemicals, vitamin E and folic acid.
- Mineral pigments. It is iron oxide or titanium dioxide. Apply forpink tones and ease of application.
- Boric acid. Adds shine and iridescence to pearlescent lipstick. Microparticles of quartz or mica are used for these purposes.
- Antioxidants. They are added up to 0.8% as a necessary component in all types of lipsticks. Antioxidants protect the natural substances of the product from oxidation. Usually this role is performed by the substance propyl gillate.
In addition to the required components, additional ones are added. It can be collagen, aloe vera, sunscreen and other ingredients. Product properties also depend on the composition.
What is indicated in GOSTs?
You can learn about the shelf life of lipstick from GOST. On the territory of Russia and the CIS countries there are quality standards according to which cosmetics must be produced, stored and transported. The basic rules are in:
- GOST R 52342-2005.
- GOST 31649-2012.
They are called "Fat Wax Color Cosmetics". According to the standards, the shelf life of lipstick and gloss is approved by the manufacturer.
Timing
The period before use is fixed on the packaging by all manufacturers, and after opening - by most. What is the shelf life of lipstick? Standard timings are as follows:
- Hard lipstick lasts up to 3 years before opening. What is the shelf life of lipstick after opening? It is 1 year.
- Liquid Shine - 3 years and 10-12 months respectively.
- Pencil lipstick - 3 years and 18 months.
- Lipstick-felt-tip pen - 3 years and 1 year.
- Tint - 36 and 12 months.
- Lipstick - 3 years and 12 months.
- The shelf life of hygienic lipstick and balm is 3 years and 12 months.
- Liquid Matte - 36 months and 12 months.
In the end, it all depends on the type of cosmetic products. This is important to consider when choosing these products. After the expiration date, mandatory disposal of products is required.
Different manufacturers
How long is the shelf life of lipstick from popular brands? Storage period may vary:
- Avon and Oriflame lipsticks have a shelf life of 3 years.
- Dior products are 18 months old.

Thus, almost never the expiration date of products of different brands is more than 36 months. And some firms reduce it to 2 or 1.5 years. After opening, it is advisable to stop using cosmetics after a year.
Storage rules
Lipstick is stored at room temperature. Like other decorative cosmetics, it must be protected from the rays of the sun, moisture, installation near sources of elevated temperatures. A prerequisite is a tight closure after use.
Refrigerated storage allowed?
This optionstorage allows you to increase the shelf life. In this case, it will be 1.5 times larger than when stored at room temperature.
But temperature fluctuations adversely affect cosmetics. Therefore, a one-time move to the refrigerator can lead to the fact that the product must be left there permanently, otherwise it will deteriorate.
What happens over time?
Lipstick is a contact product, so when stored for a long time, many microbes appear in it. A long service life can disrupt its structure, change its chemical composition. Over time, cosmetic substances oxidize from oxygen and become unusable.
Signs of spoilage
Since the composition contains oils and fats, an unpleasant odor can indicate spoilage. Dried, cracked or leaking product should not be used. It needs to be thrown out immediately. Damage can be understood by:
- change in taste and color;
- appearance of white plaque;
- droplets of liquid appearing on the decorative tool.
When cosmetics are poorly applied, roll, become very dry or viscous, this indicates its deterioration. You should not continue to use it, it is better to purchase a quality product.
Danger of delay
Some believe that the use of an expired remedy has no consequences. But this opinion is erroneous. This reduces the decorative properties and benefits, in addition, the product can be hazardous to he alth. Germs on old cosmetics can cause lip infections, and expired products lead to allergies.
An unpleasant consequence is the development of cheilitis, an allergic disease, which manifests itself in the form of lip cracks, exfoliation of the upper epidermis, reddening of the lip border.
Lipstick, gloss and other lip products - this is the kind of cosmetics, the expiration date of which must be observed. Since it is applied to the border of the mucosa, and a certain amount penetrates inside, you need to use fresh products.
