What is Ellanse and is it reliable?

This product is not currently approved/used in the US. I would make sure to ask your physician their experience with the product, if you are outside of the States. Best of luck.

It is not FDA approved/used in the US as of now. Are you writing from outside of the US?

What is Ellanse (“少女针”)
Ellanse is an injectable dermal filler and collagen biostimulator that restores facial volume, smooths out facial lines and firms skin. Ellanse contains30% polycaprolactone (PCL) microspheres suspended in a 70% carboxymethyl cellulose (CMC) gel carrier. Popular in Europe and Asia, it has been nicknamed “少女针” aka young woman’s injection.

How does it work
Polycaprolactone (PCL) is a medical polyester which has been used for medical purposes for over 50 years- found in sutures, orthopaedic implants and wound dressings. In the body, PCL is gradually broken down by hydrolysis into carbon dioxide and water by the body. The PCL microspheres used in Ellanse are designed to offer optimal biocompatibility. They have a smooth surface, a spherical shape and a size of approximately 25–50 μm
Carboxymethylcellulose (CMC) is a natural material derived from cellulose that is often used as a gel carrier for injectable collagen biostimulators (Ellanse, Sculptra, Radiesse). It functions to act as a medium for collagen biostimulator particles, and to provide short term volume replacement for 2-3 months.
Working together, the CMC gel delivers immediate results, while the PCL microspheres act as a biostimulator, to ramp up production of your own collagen over the next 2-3 months. This improves skin elasticity and creates a more youthful appearance.
