Will Ellanse really be absorbed by the body after the time label? Will it disappear completely?

I had ellanse on my face about 1y ago, I chose the product that lasted 2yrs, but my face got asymmetrical, my doctor said we have nothing to do and we must wait for time label to pass, so, 1 more y. I asked him to try to dissolve the product and he told me that it's no longer possible after 1y of the procedure but to be calm about it, because it will dissapear as the time of the label chosed, Will the product really be absorbed? is there any risk of this product remain forever in my face?
