I'm starting to spit stitches on my face and fear the scar is going to get wider! Is there anything I can do to stop it? (Photo)

I had and abnormal mole re-excised on my fave about 4 weeks ago. I thought I was just getting a pimple on the suture line but it ened up being a suture. I have another one comeing out too right in the middle. I fear the scar is going to spread. I had a similar problem with an excision site on my chest that turned out horribly and I dont want that to happen to my face!
