How to know if your lipstick is expired? What are the characteristics of lipstick deterioration?

Lipstick cannot be used after it expires. Many people will buy many lipsticks of different colors, but they cannot use them all. Lipstick will expire after a period of time, and the texture, color and smell of expired lipstick will change.

The appearance of expired lipstick will change significantly. The color of the lipstick paste will not be as bright as when it was just opened, and the shape of the paste may be deformed. In terms of smell, seriously expired lipstick will emit a pungent smell. The safest way is of course to check the shelf life. If the lipstick has expired, it is better not to use it. Lipstick is a product that is very easy to expire. This is not because its shelf life is short, but because many people will open many kinds of lipsticks at the same time. After all, different makeups require different colors of lipsticks, and different moods also require different colors of lipsticks. Some lipsticks may be forgotten in the corner for a long time after a short use, and then they will quietly expire. If you want to determine whether a lipstick has expired, the simplest and most direct way is to check the shelf life. However, if the lipstick packaging has been thrown away, the method of checking the shelf life is not easy to use. At this time, you have to start with the lipstick itself. Expired lipstick will emit a more pungent smell. At this time, this lipstick should never be used again. In addition to the smell, you can also distinguish it by looking at the color and shape. If the color is uneven or different from the previous color, or the shape of the lipstick paste has changed, then this lipstick is basically expired.

1: Color

Normally, lipsticks within the shelf life are bright in color, with high saturation and a fuller feeling when applied. However, if your lipstick is expired, the color of the lipstick may be thinner and the saturation may not be so high. When applying makeup, you will obviously feel that the color of the lipstick is uneven, and the lipstick may not be as moisturizing as when you first bought it. When you tell whether your lipstick is expired, the color of the lipstick is direct and clear. If the lipstick you bought is not as bright as before, or some lipsticks may grow hair, you should pay attention to it. Your lipstick may have expired. Even if it is a good lipstick, you may have to give it up reluctantly.

2: The feeling of putting on makeup

Another way to check whether your lipstick is expired is to feel it when you put it on. If you can clearly feel that the color rendering of your lipstick is not as good as before, or the lipstick is easy to come off and disappears after a while, then your lipstick may be expired. Of course, this situation often excludes some cheap lipsticks, because some relatively cheap lipsticks themselves have poor color rendering and durability. In short, if the color of the lipstick becomes lighter or darker, you should consider whether your lipstick is expired.

3: Texture

Most lipsticks within their shelf life will give people a thick and solid feeling when applied, but if the lipstick is out of its shelf life, it may become easy to break or melt. The texture of the lipstick will become worse than before, and some melted white particles may appear on the lipstick paste. The lipstick will become very soft, the coloring power will also be weakened, and the effect of application will be different from before. When this happens, your lipstick may also be expired. However, it is not ruled out that some lipsticks may have oil condensation on the surface of the paste due to high and low temperatures.

4. Smell

Lipstick usually has a light fragrance, not so pungent, and this smell is very pure, but expired lipstick, not only the texture changes, the smell of lipstick will also change, just like the smell of rotting food. Generally speaking, spoiled lipstick will give people a pungent smell or a pungent smell like plastic, such lipstick may also have expired.

It is not recommended to use lipstick after it produces water droplets, as it will affect the health of your lips. It is possible that lipstick will produce water droplets in the summer. The temperature in the summer is too high, which will cause the oil, Vaseline and other substances in the lipstick to melt, so you need to put the lipstick in the refrigerator in the summer to prevent it from melting. There is also a type of lipstick that will produce water droplets regardless of summer or winter. Generally, this type of lipstick can be thrown away directly, as there may be other substances in the lipstick.

Lipstick is a kind of cosmetics, which is suitable to be placed in the refrigerator. You should also pay attention to the refrigerator.
