How to get rid of thick nodule-like things under my skin after Ellanse filler?

I suggest seeing a cosmetic dermatologist or plastic surgeon that treats a lot of filler complications.  Please see an expert.  Dr. Emer.

What you are experiencing is a reaction to the filler in which your body walls off particles and they turn into nodules. This happens although uncommonly with fillers like ellanse and sculptra. The nodules need to be broken up or removed. I recommend that you come in and are evaluated properly in order to find the perfect solution for you. 

Hi! sorry to hear about your experience. You can consult your provider, some possible solutions are massage to even out the product, or steroid injections


Ellanse at Bay Aesthetics Clinic

Ellanse is one of the top treatments at Bay Aesthetics Clinic and a high volume of treatments are performed. Our treatment philosophy is for natural and subtle results, avoiding “overfilling” clients for a “puffy” look. For full face rejuvenation, we typically divide the treatment into 2 sessions, doing 2-4 syringes per session. This careful approach reduces the swelling and discomfort after the treatment, and our clients are able to return to normal activity right away without any downtime.

One of the main instructions about Ellanse is : DO NOT EVER DILUTE IT WITH MORE THAN 0.2CC OF LIDOCAINE OR NORMAL SALINE. 
One of the possible causes of excessive puffiness could be that your doctor over-diluted the Ellanse.
One of the possible causes of palpable nodules is possibly over-injection of a certain area. 
I see Ellanse complications a lot from other practices, being the first Ellanse trainer in Singapore. A good solution is to dilute kenacort with hyaluronidase and inject into the palpable lump. 
Do find a suitable Ellanse trainer in your country, hope that helps!
