Can expired pearl powder be used?

The skin care industry is changing with each passing day, mainly because people nowadays attach great importance to skin care and hope to make themselves look younger by taking care of their skin. So, can expired pearl powder be used? Some people think that there is no big problem, and of course some people think that it is completely unusable. If you don’t know, let us find out together: can expired pearl powder be used?

Pearl powder is a good thing, but people often ask me, will pearl powder expire? What is the shelf life of pearl powder? Someone asked me: I have a lot of pearl powder from several years ago. There is no expiration date written on it. Will it expire?

Pearl powder will expire, and the pearl powder sold in most drug stores has a shelf life of two years. Of course, expiration does not mean that it cannot be used. First, you can smell it. If there is a strong fishy smell, it means that it has deteriorated. Secondly, look at the gloss. Generally, pearl powder with good color will have flashing bright spots under the light. The color will be proportional to the time. The longer the time, the darker it will be. That also depends on where you put it. If it's in a sunny place, it's hard to say, because many substances are affected by light and will have chemical reactions. But if you put it in a cool and dry place and seal it, it can be stored for a long time. However, generally speaking, you don't keep it until it expires after you use it. A pack will be used up in just a few weeks.

So how do you tell whether cosmetics are expired or spoiled? Expired cosmetics often have the following manifestations:

1. Changes in product color. As some colored and colorless microorganisms grow, they will produce metabolites, which will of course be directly secreted into the product. A common occurrence is that the original white paste turns light yellow, develops mold spots of different colors, or simply becomes moldy. Some products containing unstable vitamin C will turn yellow over time. They are not expired, but they have lost their effectiveness, so it is better not to use them.

2. Changes in 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. Microbial action also produces some volatile substances, such as sulfide-like odors, and acid gases produced by the decomposition of organic acids in cosmetics. Anyway, it is a sour and pungent smell. When you find that your product has a strange smell, throwing it away is the best option. Jingrun Pearl's nano pearl powder is the best pearl powder once you use it!

In order to avoid the threat of spoiled cosmetics to us, in addition to understanding 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 frequently used in the refrigerator. These methods are all good ways to reduce the risk of bacterial growth.

Will pearl powder expire? The answer is yes. Any product has a shelf life. As long as you buy pearl powder from a regular shopping mall, pharmacy or official website and take it according to the time on the instructions, you will be fine.

Through the answer to the question of whether expired pearl powder can be used, we can see that although pearl powder has many functions, expired pearl powder should not be used, because it has no effect on our skin. Do not continue to use it because of heartache or other reasons. Of course, when purchasing skin care products, you should also buy better ones, which is also better for our skin.
