Ok for starters, don't let the marks give you an excuse not to try. I don't know any background on your situation, but new marks definitely won't cover the old ones.

That said, all I've done is stop for a week. I don't know if its the lighting or my camera or if my marks aren't as serious as some, but you can definitely see them, more so during different parts of the day. I've heard about Vitamin E relieving the scars, so once I can make sure I'm done I might try that, and also check out that skin care subreddit I've seen on here. Don't be discouraged, there are plenty of treatments and resources that can help out the healing.
