Ellanse - fillers for bioreinforcement and contouring. Ellanse fillers are based on carboxymethyl cellulose and synthetic polycaprolactone microspheres. The composition of Ellanse fillers provides an immediate filling effect and subsequent stimulation of own collagen production, i.e. neocollagenogenesis. Ellanse is a non-permanent, non-pyrogenic, biocompatible, and bioabsorbable synthetic dermal filler consisting mainly of polycaprolactone (PCL) microspheres suspended in a water-based carboxymethylcellulose gel carrier.
