I got a 20-year-old chicken pox scar punched out, and sewed back together 5 months ago. So far I feel like the scar looks worse than before. My skin has sunken down, and the direction the scar was closed, has created a wrinkle in my skin. I also have a small bump sticking out of my skin, which I think is scar tissue. I feel very self-conscious about my new scar and unfortunately, regret the procedure. Is there anything I can do to improve the scar I have now?
