How long until shave biopsy spot fills in and swelling goes down?

I had a shave biopsy done 5 weeks ago on my cheek. The spot is still indented. 1) how long will it continue to fill in? 2) any harm from massaging? I hear massaging breaks down scar tissue, so is that bad since I want it to continue to create scar tissue to fill in? 3) the spot & also lower eyelid is still swollen. Is it normal this long? 4) when I smile my "tear trough" is more noticeable b/c I think the inflexiblity of the scar tissue is concentrating the crease. What to do to minimize this?
