1. Is vacuum cosmetic packaging equal to sterility?

The purpose of vacuuming is to delay product deterioration. After the finished cosmetic product is filled into the bottle, the gas will be pumped out through the machine to make the bacteria lose the hotbed of survival. However, whether or not bacteria enters depends on the manufacturing process of the cosmetics and the preservation status during use. The process of making cosmetics is not a vacuum environment, so the purchase of regular qualified cosmetics can ensure hygiene and safety. In order to avoid bacterial growth during use, preservatives are added to the ingredients, but they will deteriorate if not properly preserved.

2. How do you tell if a cosmetic breeds bacteria?

Cosmetics contaminated with bacteria are as terrible as expired cosmetics, which can cause long acne, which can cause suppuration and infection, especially for sensitive skin. Cosmetics start to turn yellow or the smell becomes pungent, which means that the product begins to deteriorate and can no longer be used.

3. Can vacuum cosmetic packaging really last longer?

The oxygen in the bottle is reduced after vacuuming, which prevents oxidation of the components, stabilizes the activity of the components, and inhibits the survival of the microorganisms, thereby prolonging the storage time. However, the skin care product is a liquid, and it is impossible to completely evacuate like a solid, so the extension time is limited.

4. Are all the packages that appear to be sealed vacuumed?

Judging whether the vacuum bottle is only looking at the pores at the bottom of the bottle, there is, if not, not. Covering the suction holes will result in the inability to squeeze. Most sealed packages are designed to remove excess air after production and are not really vacuumed. Our common spray is a design that uses nitrogen to pressurize the bottle, nor is it vacuum.
