Eyeshadow can be considered the product with the longest shelf life in cosmetics. Whether it is unopened or opened, the use period is very long, so many people use it and do not know if it has expired. Today, let’s look at how to judge the expiration date of the eyeshadow.
What’s the harm if you use the expired eyeshadow?
If you use the expired eyeshadow, the fat granules will grow around the eyes, and some even cause allergies around the eyes. Do not use the expired eyeshadows anymore. Expired eyeshadows will change in texture and composition, seriously affecting the effect of use and sometimes clog the skin’s pores, causing some skin problems. Most eyeshadow products have a shelf life of 3 to 5 years before they are opened, and there are also these powdery make-up products. The shelf life will be about five years. It will shorten the shelf life after you open the eyeshadow. Most expired eyeshadows don’t look much different from the new ones, so many people will continue to use them. The texture of expired eyeshadows has already happened. Even if the change is not visible on the outside, it is easy to cause pore blockage if you use it again, so it is better not to use the expired eyeshadow. Opened cosmetics are in contact with the air for a long time, and the active ingredients undergo chemical changes. The shelf life refers to the time the eyeshadow is stored without opening. Once the eyeshadow is opened, it will enter the fresh-keeping period. Excessive exposure to oxygen will exceed the shelf life before opening. Whether from a safety perspective or a practical perspective, the eyeshadow product should be used within the shelf life.
Look at the production date and shelf life
Looking at the production date is a relatively simple and convenient method to know whether the eyeshadow has expired or not.
Look at the texture of the eyeshadow
If the eyeshadow powder has expired or deteriorated, paste agglomeration and the broken phenomenon will appear. And the liquid eyeshadow will appear to be coagulation or drying.
Smell the odor of the eyeshadow
If the eyeshadow powder has expired or deteriorated, there will be a musty smell or chemical smell caused by improper storage. It is better not to continue using the eyeshadow in this situation.
Look at the separation of water and oil.
The surface of the expired eyeshadow powder may have a layer of water droplets, and the liquid eyeshadow will have a layer of glitter and liquid, which proves that the eye shadow has expired or deteriorated.
Look at the Changes in the eyeshadow’s color.
Due to the growth of some colored and colorless microorganisms, they will have metabolites, and these metabolites are, of course, secreted directly into the product (it’s disgusting to think about). It is common for the original white paste turns pale yellow and produces different colors of mildew spots or simply direct mildew. (Some products containing unstable vitamin C will turn yellow after a long time, which is not expired, but the efficacy is no longer there, so you don’t need it.)
In conclusion, if we want to prevent expired eyeshadow from threatening us, we could read the production date of the eyeshadow or strictly implement the shelf life of the open box. We also need to take better care of our eyeshadows by placing them in a dark and dry place. Keeping the eyeshadow palette that you use in the refrigerator is a good way to reduce the risk of bacterial growth.
