How to get rid of self harm scars?

There really isn't a way, but there is a vitamin E that will fade. And there is an ointment that will help more

You could always try and cover them. Try a healing cream, like Sudocream. This will work after a while and will fade away the scars eventually.

For my scars, i mix a little bit of oil and sugar together to make a scrub. And then i rub it on the area of the scar 3 times a week,

I know that there is a cream you can buy in some stores to get rid of scars in general. That may help?

I've had a lot of luck with Bio oil - and I have heard rose hip oil also works. You can also buy special patches, mainly for keloid scarring, which are expensive but work wonders in making scars flatter and less red. Long sleeve clothing is a pretty common cover up method but you can also consider trying body foundations which are thicker and often water proof. It's sometimes worth seeing a GP they may be able to refer you to a plastic surgeon who can help reduce some kinds of scars, but often when they wont want to cut out a scar because you'll still be left with a scar - but I have heard skin grafts can be an option.

Well there isnt really a way I guess you could use makeup Foundation is what I use It helps cover up

There are some scar creams out on the market and I'm sure that some of them will be helpful. I would recommend going on Amazon.com to see what the reviews are.

Coconut oil and cocoa butter works pretty well. Definitely helps fade them. Those are the only two remedies that I've tried and noticed a difference. :)

As far as I'm aware, you can't get rid of them entirely, however they can be treated with an anti-scarring cream.

Use olive oil. Extra virgin olive oil can help reduce the appearance of scars. Massage a small amount of 100% extra virgin olive oil into your skin once or twice a day for several weeks or months
