They contain moisturizers and vitamins to help heal and cover scars with natural looking skin. If this doesnt work, you can always go to a dermatologist and ask them for prescription grade scar cream.|||About remove dark scars can be read in http://health-schools.blogspot.com/?q=remove%20dark%20scars|||Ask your docter, they would know the exact procedure.
