The vacuum packed product is different from the common standard pump of pipette type. The vacuum packed product uses the principle of separating the inner cavity to squeeze the contents out.

When the inner membrane moves up to the inside of the bottle, forming a pressure, the contents are in a vacuum state of nearly 100%.

It consumes less resources and can also be recognized as "green".

Vacuum packaging also provides precise dosage control

The design of the vacuum pump head of skin care products is to use the retracting force of the spring to prevent air from entering the bottle, resulting in a vacuum state, so as to achieve the use result of "only out, not in".

Each time the pump head is pressed, the small piston at the bottom of the bottle will move upward, and no air will enter when the material body comes out. With the reduction of the material body, the space is less and less, so that the product does not have to worry about the air entering from opening to using up.

This has the advantage of preventing the product components from being oxidized and stabilizing their activity; It can inhibit the propagation and growth of microorganisms to a certain extent and avoid pollution.

This can help reduce the addition of preservatives, so that the product can maintain the stability of the formula during use.
