The Princess filler range may be used in almost all facial areas. A perfect product for lip volume increase, highlighting Cupid´s bow, filling in fine lines and effective removal of facial scars. It is long lasting, but not permanent. Princess fillers are monophasic, complex and viscoelastic. Which makes them perfectly smooth and highly elastic at the same time. The products give natural and long-lasting effects, enduring from 6-12 months. Princess products were created using revolutionary, patent-protected S.M.A.R.T technology (Supreme Monophasic and Reticulated Technology). Only pure and natural hyaluronic acid of bio fermentative origin is used as a basic for the S.M.A.R.T synthesis. This process uses the well-established BDDE (Butanedioldiglycidether) as reticulation agent to create a very dense HA network and perfectly clear gel consisting of very long, strong and stable chains of hyaluronic acid.
