Will this scar continue to fill in and flatten out or will it need a revision? (Photo)

I got a mole excised by a plastic surgeon from my upper lip 3 weeks ago. This is what it currently looks like and I’m getting quite concerned about it. Does this look normal for being 3 weeks in? Will this continue to flatten out and fill in? Will the horizontal marks from the suturing go away or are they permanent? Will I need a scar revision for this? What is the best treatment at this point? Silicone sheets or gel?
