How long is the shelf life of loose powder? What happens if loose powder expires?

Loose powder is not only used once in makeup. It is often used after base makeup and before eye makeup. Of course, everyone has different makeup habits and the frequency of using loose powder is also different. So how long is the shelf life of loose powder?

Generally, the shelf life of loose powder is two years, but this is only limited to unopened loose powder. If the loose powder is opened, it is generally best to use it within six months. Otherwise, its effect may be greatly reduced and it will not be as good as when it was first used. You should know that the loose powder that has been opened is often exposed to the air, which not only has a poor effect, but also breeds bacteria and dust. Therefore, it is necessary to store it well after opening it. Generally, when not in use, put the lid on and put it in a cool and dry place to avoid direct sunlight. If the loose powder is damp, it may condense into lumps, reducing the effect of use.

The harm of expired loose powder is that it can cause damage to the skin. Loose powder is a very useful base makeup product. Its function is to set the makeup, increase the durability of the makeup, and has the effect of removing oil and controlling oil. When using loose powder, you must pay attention to whether the loose powder is within the shelf life. Expired loose powder is very harmful to the skin. Loose powder contains a variety of substances, which have a certain shelf life. When these substances are out of the shelf life, they will deteriorate. Deteriorated loose powder not only affects the makeup, but also easily causes skin allergies, causing redness, itching, and rashes on the skin. Due to the deterioration of ingredients, expired loose powder has turned the entire loose powder into a breeding ground for bacteria. After use, it will clog the pores and cause folliculitis, resulting in acne on the skin. Long-term use of expired and deteriorated loose powder may cause skin lesions.

There is such a possibility. Because the properties of some ingredients in the expired loose powder may change, not only will it be ineffective, but it may also damage the skin, so it may damage the face. However, it does not mean that using expired loose powder once will cause such serious problems. Of course, it is best not to use it once it expires to avoid other injuries or skin allergies.
