The hyaluronic acid contained in SISTHAEMA HEVO T is processed in a particular way; through the Selective Spectrum Technology (SST) the most suitable molecular weight spectrums are selected for the treatment, maximizing the effectiveness of the final product. In addition, different molecular weights are included in the injectable gel, to increase the softness of the product as well as the tensive and moisturizing effect. The fragmentation of hyaluronic acid in SISTHAEMA HEVO T helps stimulate the production of type III collagen more effectively. To do all this, we use a high purity hyaluronic acid, defined as “pharma” grade, to maximize quality and safety for the end-user. Next to hyaluronic acid there is trehalose, a sugar-like molecule, capable of protecting hyaluronic acid from degradation processes while maintaining its characteristics and therefore its regenerative effects much longer. Trehalose is also able to attract significant quantities of water, thus providing an additional moisturizing effect that enhances the effectiveness of hyaluronic acid.
