Yeah I agree with you, since he already tried subcision, I think fillers will make a huge difference for the fat loss looking scar from the first picture of Ozay. I had that exact type of scar on my lower chin area, and after getting fillers done, it leveled out my skin soo nicely and it never bothered me again. It also helps erasing those ugly scarred lines you get when you smile. It's true what you said about the confidence boost. Since the results for fillers don't fade away in a week or two, the confidence stays with you. I swear, every other scar treatment will give you false hope/confidence for two weeks and after the microswelling is gone, you lose hope and go back to being depressed. It's happened to me so many times. More people should really try fillers. I've noticed alot of angry/depressed people here have never tried fillers before. I know it has a bad rep but if you tried everything, might as well try fillers. I got permanent micro silicone droplet injected into my scars, It was my last resort and I'm glad I didn't listen to all the negative stuff about it, it was in fact the best decision I've ever made. It was the only scar treatment that gave me confidence that'll last me years instead of two freaking weeks.
TLDR: Get fillers
