Your going to need to look for exfoliating ingredients in products that help take of the scar and help produce new skin around it. So things like AHA’s (glycolic acid), BHA’s (salicylic acid), and azelaic acid. What also helps are ingredients that help skin texture like niacinamide and retinoids. These will take a while to work so if you want something that is going a bit more fast acting professional treatments like micro needling is also good.
