Concerned About Injections to Dissolve Stitches After Upper and Lower Eyelid Surgery

I am happy with how one lower and one upper turned out. I did it because I had excess skin on upper lids and hollow dark circles under eys. The post op brusing was very bad. I looked like I was beaten and the brusing lasted for several weeks.

I had upper & lower eyelid surgery in June. Was told that any scars would be hidden in the creases of eyelid. Surgeon told me that he used dissolvable stitches and that they haven't completely dissolved yet. In mid-January he will inject something to make the stitches dissolve. I am worried that it may be worse if I do this...what do you think? What else can be done?
