Sisley has chosen Irresistible Airless by Aptar Beauty for its new face care product for sensitive skin, formulated with 100 % ingredients of natural origin. The French brand selected this solution for its high-protection airless technology, reinforced by a patented barrier system preventing microbiological contamination.
High-tech packaging
Irresistible is the airless solution offering the highest level of protection in the Aptar Beauty portfolio. It incorporates a patented barrier technology specifically designed for preservative-free formulas: the Preservative-Free System (PFS). The PFS combines sterilizing micro-filters in the pump with a hermetically sealed tip (Tip Seal system), preventing any microbiological retro-contamination of the formula.
The preservative-free formula of Peaux Sensibles Soin Apaisant by Sisley is protected in a hermetically sealed bag-in-bottle inside the bottle. Any contact with the metal of the pump is avoided.
This multi-layer pouch reinforces the barrier properties of the PFS system against airborne bacteria and other external contaminants.
The Irresistible pump, with its POM-free motor, dispenses a constant dosage of 150 µl via a lockable push-button. An all-plastic version, made entirely from polyolefins and featuring a Pfas-free microfilter, is currently under development and will be available in early 2026.
Specific packaging
To make Sisley's expert formula completely preservative-free, Aptar Beauty called on the French P&B Group and its patented UHT (Ultra High Temperature) technology. This dynamic technological process of rapid heating followed by immediate cooling ensures the total destruction of micro-organisms.
Exposure time and temperature are controlled and adapted to the type of formula and its viscosity, in order to preserve formula quality and properties. A dedicated vacuum filling line, operating in a sterile environment, has been developed to avoid any contamination during filling or assembly.
Irresistible by Aptar has validated the CVIT¹ and TSIT² microbiological approval protocols, which guarantee the absence of contamination before and after opening (PAO). Throughout its use, this packaging protects Sisley's preservative-free formula from internal microbial contamination, as well as from external aggressions such as contact with fingers or ambient air.
"Irresistible Airless is our solution best suited to consumer expectations for preservative-free products, guaranteeing their safety, quality and integrity. UHT technology is particularly relevant for high value-added products, such as Sisley's Soin Apaisant."says Florence Roullet, Laboratory Development & Quality Manager, Aptar Beauty.
Sisley's Peaux Sensibles 40 ml soothing skin care product is made in France and decorated with a sophisticated double-pass silk-screen print, in keeping with the brand's aesthetic universe. The product's shiny silver metal trim adds a premium touch.
¹ CVIT (Container Ventilation Integrity Test): tests the integrity of connections between different parts (moving, static, functional) to assess the risk of microbial contamination via ambient air.
² TSIT (Tip Seal Integrity Test): subjects the pump system to intense and repeated microbial contamination in a humid environment, simulating the risks of everyday use, including contact with users' fingers.
