The Lidocaine free series comprises three products (S, M, H), each with varying HA gel grain sizes tailored for specific applications. Sosum fillers exhibit superior resistance to degradation, resulting in prolonged effects, and feature high elasticity and viscosity to ensure uniform gel distribution within the dermal layers. Sosum is a premium range of stabilised HA fillers, distinguished by their exceptional cross-linking rate. The gel's high density and finely-packed molecular structure are achieved through Low-Temperature Stabilization Reaction technology. The high cross-linking rate prevents lump formation, ensuring uniform gel distribution. The gel's high viscosity enhances resistance to degradation, providing longer-lasting results. The finely-divided gel structure ensures even distribution during injection, minimising pain and reducing the risk of post-injection oedema and bruising.
