Ellansé is a hybrid bio-stimulating filler consisting of a short-lasting filler component called CMC (carboxymethyl cellulose) and a long-lasting biostimulator called PCL (polycaprolactone).
When Ellansé is injected into the skin, the CMC provides an immediate lift to volume deficient areas. PCL triggers collagen production in the skin while CMC is rapidly reabsorbed. Biostimulation leads to a long-lasting rejuvenation of between 1-4 years depending on the preparation used. At this point in time, Singapore's Health Science Authority (HSA) has only approved the use of the S and M version which lasts for 1 and 2 years respectively.
In my experience, Ellansé gives very good lift over the cheeks, chin, nose, temples, and forehead. Compared to hyaluronic acid fillers, it has less water retention and compared to pure bio-stimulators like Sculptra, it has more rapid results.
Ultimately, the decision to use any dermal filler depends on the treatment location, desired results, as well as the preferences of the patient and the experience of the doctor in using the product.
