Opalescence

Teeth whitening brand Opalescence has introduced pre-filled Opalescence Go Advanced whitening trays, said to remove the need for an outer placement tray and reduce packaging waste.

The company states that each patented UltraFit tray is pre-filled with whitening gel to ensure consistent distribution and precise placement during treatment, with a one-step application process. The trays are available in 15% hydrogen peroxide concentration with a Cool Mint flavour.

Opalescence adds that the trays are ‘clinically proven’ to whiten teeth by up to 5 shades and Opalescence Go Advanced whitening has been designed by dentists to be gentle on teeth.

Opalescence Whitening’s Chief Clinical Officer, Dr. Jaleena Fischer-Jessop, comments: “My patients want fast, long-lasting, at-home teeth whitening they can trust and use safely while still getting top-tier results,” says Opalescence Whitening’s Chief Clinical Officer, Dr. Jaleena Fischer-Jessop. “By pairing the UltraFit tray with our advanced whitening formula, we’re offering a straightforward, effective, and convenient way to brighten smiles.”

In related news, last year West Pharmaceutical Services (West) unveiled its West Synchrony Prefillable Syringe (PFS) System at CPHI Worldwide in Frankfurt, Germany, offering a ‘fully verified’ platform from a single supplier. The system has a single design verification and characterization package which ensures the form, fit and function of the entire PFS system.

The same month, Ypsomed revealed its pre-filled autoinjector designed for automated disassembly, streamlined recycling, and an 87% reduction in material-related CO2 emissions compared to conventional alternatives. It comprises two mono-material, bio-based subassemblies, one for the syringe unit and another for the drive unit, set to simplify the industrial separation, recovery and recirculation of materials.
