Congratulations Murderface. Don't despair, those scars will fade. I haven't burned myself for a year. Only one of my deepest scars is still a little bit purple and is clearly fading.

Till then, you may want to think about using one of the long lasting cosmetic concealer they can last a few hours on an arm, or look into skin camouflage https://www.changingfaces.org.uk they do help people who self harmed as well and helped me.
