1. How to open the vacuum press bottle
To press the bottle in a vacuum, you can use scissors or other slightly sharper tools to pry open the edges a bit to let the air flow in. Pay attention to safety when using tools. In addition, for some special or different product suggestions, look at the opening method marked in the manual, check whether your opening method is correct, or consult professionals and shop assistants.

2. Steps to disassemble the cosmetic airless bottle
Cover with warm water and a hot towel, which means that the negative pressure of the cold weather will absorb the air inside, and the volume of gas inside will become smaller. After the heat is covered, the volume of air inside will become larger, the negative pressure will be smaller, and it will be easier to unscrew. Airless bottles are different from general containers that use long tubes to suck up care products or simply cover them with a lid. The vacuum bottle uses a short vacuum tube and a piston at the bottom to remove the air in the bottle, and the inside is vacuumed by pressing. This technology can prevent the content from contacting the air, remove the doubts about oxidation and deterioration of the product, and achieve the benefits of anti-oxidation, anti-pollution, and no residue. Do not open the body of the vacuum bottle during use. If you accidentally open it, cover it back as soon as possible, so as to prevent the pressure difference between the inside and outside of the bottle from becoming zero and affecting the use of the vacuum pump.

3. Can the airless bottle of skin care products be taken apart?
The used skin care product bottle can be opened, but the skin care product bottle that is still in use cannot be opened. The safety, sealing, and light transmittance of the skin care product container directly affect the freshness, effect, and activity of the skin care product. The airless bottle is the best bottler to solve the oxidation/qualitative change of the skin care product paste due to contact with air/bacteria.

4. How to restore the vacuum bottle when it is used up
You can first disassemble the pump head, etc., and then poke the tray down with a hard object longer than the bottle, and the vacuum bottle will be restored. After the pump head of the vacuum bottle is restored, the vacuum bottle can be filled with cosmetics again and reused. But wash the bottle clean before loading. Generally speaking, when the vacuum bottle is pressed, the bottom tray will run up to squeeze out the contents. When the contents are used up, the tray has already moved to the top. To reuse it is to press the tray that ran to the top again, and that's it. In cosmetics, airless bottles are very beneficial, which can completely isolate external bacteria from the cosmetics in the airless bottles. The contents of the airless bottle can be completely isolated from the air to prevent the product from oxidizing and deteriorating and breeding bacteria due to contact with the air. The airless bottle currently in the market is composed of a cylindrical ellipsoidal container and a piston at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward.
