The text discusses the concept of clean beauty as it applies to hyaluronic acid fillers, emphasizing transparency and purity. It highlights fillers like Decoria Pure from Sweden, which feature minimal synthetic additives, such as BDDE used as a cross-linking agent, and exceptionally high purity of hyaluronic acid. This approach aims for better compatibility with the body. The low degree of cross-linking allows for the injection of a natural hyaluronic acid that offers longer-lasting results without unnecessary residues or stimulation of the immune system. The overall focus is on prioritizing safety and quality in cosmetic practices.
