How to dissolve Ellanse fillers in the chin? (photos)

Ellansé is a biostimulatory filler with an impeccable track record, unlike for other biostimulatory fillers. Its active ingredient is polycaprolactone, and the filler is wholly bioresorbable, stimulating the production of collagen in the process. Unlike with hyaluronate fillers, Ellansé cannot be dissolved. At best, within the first few days, very firm pressure may assist with spreading it/ redistributing it. Therefore, I'm afraid that you cannot reverse the treatment you've had. 
I do not understand what you have tried to achieve, although this may simply be a case of description-error/ choice of words. After looking at your photo, my suggestion is that your physician should use some botulinum toxin (e.g. Xeomin) to relax your chin (mentalis muscle). Most women prefer a soft jawline, i.e. one that is not very angular, so an idea is to use a heavy (high G') hyaluronic acid-based filler (e.g. Teosyal Ultimate) to help achieve this. 
Do remember that beauty involves concepts of proportion, so make sure you have a discussion about balance, and ensure that you reflect on the overall shape and appearance of your face (as opposed to looking at the chin/ jawline in isolation). 

Ellanse cannot be dissolved by Hyaluronidase
It is possible to reduce the effect of Ellanse with steroid injections, but at the risk of skin atrophy

Who is Ellanse suitable for?
Ellanse is suitable for individuals seeking facial rejuvenation, restoring facial volume lost due to the natural ageing process and tightening the skin. Most clients start doing Ellanse in their 30s and 40s when early signs of facial ageing develop.

Ellanse vs Hyaluronic acid based fillers
Ellanse has a longer duration of action (18-24 months) compared to the traditional hyaluronic acid (“HA Filler”) gel based fillers (9-12 months), with the added benefit of collagen stimulation and skin tightening. However, unlike HA Fillers which can be dissolved with the antidote hyaluronidase, Ellanse cannot be reversed. Ellanse is also not used in sensitive areas such as the undereye and lips. For clients getting fillers for the first time or considering treatment of the undereye and lips- HA fillers would be the better choice. For clients who have had HA Fillers before, liked the result and are hoping for a longer lasting treatment- Ellanse would be a good option.

Ellanse vs collagen biostimulators
The 3 Collagen Biostimulators locally approved are: Ellanse (PCL), Sculptra (PLLA- Poly L Lactic Acid), Radiesse (Calcium hydroxyapatite). These products have a long track record of safety and effectiveness. As a rule of thumb, Ellanse provides more volumisation and Sculptra more skin tightening effect. Radiesse can be hyperdiluted for treatment of the body and hands.

Safety of Ellanse
Ellanse received European approval (“CE Mark”) since 2009 and is also approved by Singapore’s HSA, Korea’s K-FDA and China’s health authorities. PCL and CMC have been used in medical devices for over 40 years and are classified by US FDA as “Generally Regarded as Safe”. Over 2 million treatments have been performed worldwide
