Does gel eyeliner have a shelf life? Can gel eyeliner still be used after it expires?

Eyeliner is a cosmetic product that many people often use. At the same time, we all know that cosmetics have a certain shelf life. So here we need to know whether eyeliner has a shelf life? Can eyeliner still be used after it expires?

Yes. The shelf life of eyeliner is generally 1 year. If there are white heads on the tip of the eyeliner that cannot be cut off, throw it away. If the eyeliner is opened, it is best to use it up within 6 months to 1 year. If the eyeliner is abnormally easy to remove, this is a sign that the eyeliner is expired. The shelf life of eyeliner cream and eyeliner liquid is generally 3 months. The life of liquid eyeliner does not exceed half a year. In order to protect your eyes, if you find signs of expiration, it is best to throw it away. It is recommended to use up the eyeliner within eight months after opening. If the unopened eyeliner exceeds the shelf life, it is best not to use it, because expired eyeliner is easy to breed bacteria, and the skin around the eyes is already very fragile, so it is best not to use it. It is best not to use an opened eyeliner for no more than 3 months, which can reduce the chance of the eyes being infected by bacteria on the eyeliner.

It is best not to use expired eyeliner, because expired eyeliner is easy to breed bacteria, and the skin around the eyes is fragile, so it is best not to use it. Gel eyeliner can only last for six to eight months because you keep getting other cosmetics on the brush and putting them in the jar. Pencils have a shelf life of one year. If you use an eyeliner pencil, you can keep sharpening it, and it will not breed bacteria as easily as gel eyeliner. When you see tiny white dots on the tip of the eyeliner, and you can't remove those white dots no matter how you sharpen it, it proves that the eyeliner is expired. Be vigilant about eye cosmetics, and don't save them just because they are expensive, until they expire without knowing it. At the same time, liquid eyeliner is also one of the frequently used products. When the liquid eyeliner dries up and the pen tip starts to fluff, it proves that the liquid eyeliner should also be replaced.

Yes. Always drawing eyeliner will cause melanin to precipitate around the eyes, forming dark circles, and irritate the eye skin, which is more prone to aging and sagging. When removing makeup, don't think that the eyeliner is clean if you can't see it. It is best to wash your eyes with eyewash, because it is very likely that some small things will get into your eyes when removing makeup. The long-term habit of eyeliner can lead to eye diseases such as dry eyes. Of course, there is no harm in occasionally applying makeup, but drawing eyeliner for many years will definitely cause some damage to the eyes. Because the eyeliner is drawn at the root of the eyelashes, the root of the eyelashes is the position where the meibomian glands open, and the metabolites secreted by the meibomian glands must be discharged from here, and the eyeliner will block the opening. In addition, the long-term use of eyeliner cream will also cause damage to the skin around the eyes. If the makeup is not completely removed for a long time, the eyeliner will remain on the eyes, which may cause allergic conjunctivitis. Therefore, it is recommended to use eyeliner as little as possible.

If it is eyeliner cream, the normal specification is about 3~6g. If it is liquid eyeliner, it is usually measured in ML (milliliters) instead of CM (centimeters). The normal specification for bottled eyeliner is 2.3ml or more; the normal specification for pen is 0.7ml or more. If it is an eyeliner pen that needs to be sharpened like a pencil, it also measures a certain number of grams, usually 1.2 or more. When choosing eyeliner tools, beginners should try not to choose liquid eyeliner pens. Because most liquid eyeliner pens have soft pens and are not easy to control, it may be difficult to draw the effect you want.
