What operational misunderstandings should be avoided when using Lancel Airless Bottle?

As an innovator in the field of high-end skin care packaging, Lancel Airless Bottle has become the designated packaging material for more than 30 international brands such as Estee Lauder and SkinCeuticals with its vacuum sealing technology and precise quantitative system. However, laboratory data shows that 83% of consumers have harmful operations during use.

Misunderstanding 1: Violent pressing destroys the vacuum mechanism
In order to speed up the liquid discharge, some users repeatedly press violently or knock the bottom of the bottle upside down. The micron-level precision design of the piston in the bottle can automatically sense the pressure change, and each gentle press can trigger 0.1ml precise liquid discharge. Excessive force will cause the piston track to deform, and the product will accelerate oxidation after the vacuum environment fails.

Misunderstanding 2: Privately filling non-original products
Laboratory simulation tests show that when third-party lotions are injected into empty bottles, 73% of the products undergo chemical reactions to produce crystals. This is because the inner wall of Lancel Airless Bottle uses a medical-grade PP+EVOH seven-layer co-extruded barrier film, which has molecular compatibility with specific pH value formulas. "Even essences of the same texture may cause bottle corrosion due to differences in active ingredients." The technical engineer emphasized.

Misconception 3: Incorrect disassembly shortens service life
In response to the "bottle disassembly and recycling tutorial" circulating on the Internet, the official has issued a special warning statement: the 360° rotating buckle design of the bottle mouth has a one-way locking function, and forced prying will permanently damage the seal. The correct cleaning method should be to wipe the nozzle with a 75% alcohol cotton pad, and it is recommended to handle the monthly deep maintenance through the official after-sales channel.

Misconception 4: Improper storage in ultraviolet environment
Although the bottle body is made of UV-proof material, continuous direct sunlight will still cause two risks: ① Ultraviolet penetration causes degradation of photosensitive ingredients such as VC ② High temperature reduces the viscosity of the piston lubricating layer. It is recommended to store it in a light-proof environment with a humidity of less than 60% and a temperature of 20-25℃, and use a matching radiation protection cover when carrying it out.

Misconception 5: Ignoring the pressure balance operation
When there is 10% of the product left in the bottle, it is recommended to perform the "negative pressure reset" operation: place the bottle body vertically on a flat surface, press the pump head until it rebounds completely and hold it for 3 seconds. This action can reset the pressure system and avoid poor liquid flow caused by misjudgment of the residual volume monitor.
