What are the consequences of using expired eye shadow? What does expired eye shadow look like?

Many people like to stock up on cosmetics. Different colors of eye shadow produce different effects, and buying various types of eye shadow is also a hobby of many people. Eye shadow actually has a shelf life, so be careful with expired eye shadow.

Fat particles will grow around the eyes. It may even cause allergies around the eyes. Don’t use expired eye shadows. Expired eye shadows will change in texture and composition, which will seriously affect the effect of use. Sometimes they will clog the pores of the skin and cause some skin problems. Generally, the shelf life of cosmetics before opening is 3 to 5 years. There are also these powder cosmetics. Basically, the shelf life is about 5 years. After opening, the shelf life will be shortened. It is best to use them up within three years. If it is eye shadow cream, it may only have a shelf life of half a year. Most expired eye shadows do not look much different from new ones, so many people will continue to use them. In fact, the texture of expired eye shadows has changed. Even if it cannot be seen from the outside, it is easy to cause pores to be clogged if used again. Therefore, it is better not to use expired eye shadows. After opening, cosmetics are in contact with air for a long time, and the active ingredients in them undergo chemical changes. The shelf life refers to the storage time of the product without opening. Once the product is opened, it will enter the freshness period. If it is exposed to too much oxygen, it will exceed the shelf life before opening. Whether from the perspective of safety or the comfort of use, it must be emphasized that cosmetics should be used up within the shelf life.

1. Changes in product color

As some colored and colorless microorganisms grow, they produce metabolites, which are of course secreted directly into the product (just thinking about it makes me sick). The most common thing is that the original white paste turns light yellow, produces mold spots of different colors, or simply molds. (Some products containing unstable vitamin C will also turn yellow over time. It is not expired, but the efficacy is gone, so it is better not to use them.)

2. Change of product status

Certain microorganisms can hydrolyze the proteins and lipids in cosmetics and destroy the emulsification structure. As a result, the product will seep into water, stratify, and become turbid (mostly referring to lotions), which means that your cosmetics can no longer be used.

3. Changes in smell

Microorganisms also produce some volatile substances, such as sulfide, which produces odor, and acid gas produced by the decomposition of organic acids in cosmetics. In short, it is a sour smell, which is very pungent. When you find that your product has a strange smell, throwing it away is the best choice. In order to avoid the threat of spoiled cosmetics to us, in addition to reading the production date of cosmetics and strictly enforcing the shelf life after opening the box, we also need to better store our products, such as placing them in a dark and dry place, and placing products that are not often used in the refrigerator. These methods are all good ways to reduce the risk of bacterial growth. The shelf life of general cosmetics is five years, and the same is true for eye shadow.

The way to judge whether the eye shadow is expired can be to look at the shelf life and production date of the product, as well as the texture or smell it and look at the shape. Once the eye shadow is expired, it cannot be used, because the ingredients of the eye shadow have changed at this time, which will cause damage to the skin around the eyes, and even seriously damage the eyes. No matter what kind of cosmetics, the production date and shelf life will be written on the packaging. If the use time has exceeded the shelf life, then it can no longer be used, regardless of whether it has changed. Because after the eye shadow expires, there will be some microorganisms in it, and these microorganisms will change the texture of the eye shadow. If it is a powdered eye shadow, it will clump or break. If it is a liquid eye shadow, it will solidify and dry. Whether it is liquid eye shadow or powdered eye shadow, once the texture changes, it cannot be used. You can also tell whether the eye shadow has expired by smelling it. If the eye shadow is overheated, the chemical substances in it will change, and even some microorganisms will be produced. These microorganisms will produce certain metabolites, and these metabolites will change the taste of the eye shadow. If the taste of the eye shadow is no longer the original taste, then it cannot be used. You can also tell whether the eye shadow has expired by observing its shape. Once the eye shadow expires, the water and oil will separate. If it is powder eye shadow, a layer of water droplets will appear on the top of the eye shadow. If it is liquid eye shadow, the liquid will be layered. If the eye shadow shows any of the above changes, it should not be used anymore.

Before applying eye shadow, you should apply eye cream and foundation, which can not only reduce the damage to the skin, but also improve the moisturizing effect and make the makeup go on better. Eye cream should be applied earlier, and you should never wait until you are about to apply eye makeup, otherwise it will not have the best effect.
