Why won't my vermilion boarder filler go away or dissolve after three years? (photos)

If the filler you had put in the vermillion border was a Hyaluronic acid based filler it would not have lasted 3 years.If the touch ups involve the vermillion border and were done recently then you just need to get it dissolved. 

In our experience, temporary fillers may occasionally lead to permanent results. You appear to have a pleasing lip appearance, so the feasibility of hyaluronidase or dilute steroid injections is uncertain - hyaluronidase may dissolve HA, but it may not lead to complete resolution of your concern. Wishing you well. Dr Joseph

Especially if you have had touch ups since its placement, hyaluronic acid most definitely can persist this long and actually much longer. Bottom line if it is hyaluronic acid filler, it can be removed by injecting it with the enzyme hyaluronidase. On the other hand, if the enzyme does not break down the product, then presumable, some other filler was used instead. Unfortunately silicone oil is cheaper than hyaluronic acid fillers and unethical injectors sometimes use cheaper products to increase profit. Do your best to work with the most ethical offices even if it is more expensive.
