So its been about a year since i cured my acne through diet, but unfortunately when i first started getting acne i used to pick them which has left some scars on my forehead. I've left them for a year and there is no hyperpigmentation and they've filled in a bit but the scars are still noticeable, especially in that blue indoor light. Anything i can do at home to reduce the scarring?

What type of scars are they? You're lucky that they're on your forehead as the skin is quite taut there and scarring isn't usually very noticeable.
