There are many ways you can hide scars but before i talk about some of them i would suggest reaching out to someone it doesn't have to be your parents just someone you can trust I know it can be super scary but trust me its the right thing to do.

As someone said concealer/foundation but to add to that i would say colour corrector for like green to cancel out the red then also a easy way is just wearing clothes that cover it and there are so many things online that can help in reducing scars if you don't want your parents seeing you order then a good thing that most houses have is aloe vera which works well. And finally a way to kinda cancel out them seeing it you can do the colour corrector and foundation and then wearing (example). a short sleeve top for a bit if the scars were on your arms because then they look and there isn't scars there anymore if you get me so they get a bit confused and dismiss it

I would really really really like to make clear that i in no way think self harm is okay its really damaging and can just keep getting worse and worse if not properly addressed so keep safe and i hope you start to feel better soon ❤️

concealer and/or special effects makeup can help!

stay safe love

Bio oil: Heals them but not right away. Moisturiser mixed with concealer works unless you go underwater. I know it’s summer but try wearing long clothes
