Will Dimple/indented Skin from Internal Stitch (Transcutaneous Blepharoplasty) Go Away? (photo)

I see nothing in the provided photograph it looks alarming. There still significant swelling from the operation which can explain the contour abnormality.

This line does correspond to a typical lower eyelid line so it should hide in plain sight.  While it may bother you, I am not sure that it is that visible to others.  This line may just disappear over time and I would give it 6 to 12 months to settle before feeling compelled to do something about it.

This is a common problem in lower blepharoplasty when internal sutures are used. I think the thin skin contributes to this problem. Most likely these will resolve without surgical intervention. If not, a small needle inserted under the dimple will most likely release the dimple and resolve this issue.

Defining terms is paramount here! Was the operation a "transconjunctival" lower lid blepharoplasty vs a "transcutaneous" lower lid blepharoplasty???? If a skin incision or puncture was done than the suturing has caused this issue. Needle release under the puckering could help. If the incisions were inside the lower lid than the suturing was done with to much tissue bite. Re operation under local to re open the internal incision is needed in my opinion and best to leaver this open to heal by secondary intention. 

Some dimpling may have occurred from sutures and if so, this most likely will get better with time. Be patient.
