Will my eyelid creases go down a lot after my eyes completely heal and few months go by? (photos)

Upper eyelid platform swelling makes the crease appear higher.  It is inevitable that the hight of the crease will fall as the eyelid heals.  Despite the feeling that the current height is perfect for you, the effect is a bit overdone.  However, as you heal, the swelling dissipates, and the apparent crease height falls, your look will actually be better.  I predict that if you like your appearance today, you will like it even more when you have healed.

You are healing very well after your eyelid surgery and it look nicely performed.  You do have swelling and as it goes down the skin above the crease will descend but also tighten a bit. The height of your eyelid won't change as this is determined by the incision line and that will stay where it is at.  From what I see, I feel you will have a great result.  

The upper eyelid crease is determined by the insertion of the special muscle that opens the eye. This can be elevated to a degree with special procedure. It appears from your 5 day post-op pic that you have a very nicely placed incision of the upper lid. The swelling will subside, the length is fixed and the visibility of the scar will markedly fade with time.
