FUE hair transplant scars; what should I do? (Photo)

I was wondering what options I have to fix my scars from a FUE surgery done 4 years ago. I'm 27 and I'm scared that more hair is gonna fall off soon and leave me with no options but to shave to the skin. The scars seem to be pretty small but still very noticeable. I'm looking for any options be it laser, micro-dermabrasion, permanent makeup or any other kind of way these scars can be concealed or at least made to be less noticeable.
