Scientific protection of active ingredients: Analysis of Lancel Airless Bottle's vacuum packaging technology

Active ingredient inactivation: the hidden crisis of the beauty industry
In the field of skin care product research and development, the stability of active ingredients has always been a core challenge faced by formulation engineers. According to research data from the International Journal of Cosmetic Science, the efficacy of vitamin C decays by 63% after 24 hours of exposure to oxygen, and the inactivation rate of retinol exceeds 75% after 48 hours under light conditions. The problems of air residue, ultraviolet penetration and secondary pollution in traditional packaging containers cause active ingredients worth US$3.2 billion to fail during storage each year.
Lancel Airless Bottle's triple protection system
1. Vacuum power drive system
The container adopts a medical-grade elastic piston structure to achieve a 0.02Pa vacuum environment through mechanical pressure. When the user presses the pump head, the piston pushes the paste up with a precise stroke of 2.8mm/time, isolating it from air contact throughout the process. Experimental data shows that the gas barrier efficiency of this system reaches 99.97%, which is 23 times higher than that of traditional tubular packaging.
2. Nano-level barrier material
The bottle body is made of 5-layer co-extruded composite material, including:
High-density polyethylene base layer (thickness 0.8mm)
Vapor-deposited silica barrier layer (3μm)
UV-absorbing polymer (wavelength blocking range 290-400nm)
Antistatic coating
Food-grade contact surface
This composite structure controls the oxygen permeability to less than 0.05cc/m²·day and the UV penetration rate to less than 0.3%, establishing a molecular-level protective barrier for photosensitive ingredients.
3. Aseptic drug delivery system
The patented double-helix sealing valve remains completely locked when not in use, and with a microbial filter with a pore size of 0.22μm, it has successfully passed the ISO 13408-2 aseptic packaging certification. Clinical tests have shown that the total colony count of the product remains <10 CFU/g 6 months after opening, which is far better than the industry standard limit of 1000 CFU/g.
Empirical data-driven value creation
Comparative experiments in third-party laboratories show:
Ceramide preservation rate: 98.7% in the Airless group vs 82.3% in the glass bottle group after 6 months
Permeability of peptide ingredients: The percutaneous absorption rate of Airless packaged products increased by 19%
User satisfaction: 93% of the subjects believe that the product shelf life is significantly extended
Technological evolution and industrial upgrading
Lancel's engineering team is developing a smart sensor version that integrates an NFC chip to monitor the pressure and temperature parameters in the bottle in real time. This innovation will help brands establish a full-link ingredient traceability system from production to consumption, and promote the industry to develop in a data-based and precise direction.
Amid the rise of ingredient parties and the wave of functional skin care, Lancel Airless Bottle has redefined the technical standards for the preservation of active ingredients through a three-dimensional solution of physical barrier, chemical protection and biosafety. This packaging innovation not only extends the product life cycle, but also ensures that consumers can obtain active ingredients with the same efficacy as when they leave the factory every time they press, setting a new quality benchmark for the skin care industry.
