Any good vegan scar treatmeants?

ok, for the longest time(like six years) iv had really bad bacne(back acne) and just within the past few months, i don't know why, but it,s been really showing an improvement. im not getting as much body acne. this has possibly been a result of me cutting out soda , which i used to have an addiction for. but even thou my body acne has cleared up a lot i still have some pretty bad acne scars, especially on my upper back. i was thinking of using Palmer,s skin therapy oil , but it seems every single drugstore brand out there is only ''50 % cruelty free''. so it would really be cool if someone could point out a good vegan scar treatment that,s cruelty free, thanks
