Day 4 of permanent lip tattoo and it's formed a dark scab on upper lip. Would this cause any sort of scarring? (photo)

I got permanent lip tattoo done 4 days ago. The upper lip seems to have hardened and has clear puss coming out for which I keep cleaning with salt water. Behind the thick skin I can see the dark scab and wondering if this could scar or cause hyperpigmentation? Also, do I need to see doctor or would it heal on its own?
