Will the white scar at the corner of my mouth go away?

It's been about 4 months since I had surgery on the corners of my mouth. At first, I couldn't see the red scar because it was connected to my lips, but now it's a white scar and it's noticeable. It's
 not very noticeable, but you can see it if you look closely, but I guess that's why I keep covering my lips when people look at my face. It works.
 The hospital where I had the surgery continued to give me lasers and injections, but why did the scar remain?
 I've been applying scar ointment every day since the surgery..
 Will it be difficult to get rid of this white scar?
 I really like the shape of my lips, but I'm not satisfied with the shape of my lips.
