Hi, 3 years ago I made the mistake of having upper arm reduction. I was not properly informed of the severe scarring I would have. I am very fair skinned. The arm pit and first 3-4 inches of the incision have healed in a nice flat, skin toned scar. Since I am prone to freckles, the scar on the remainder of my arm has severe freckling in a straight line (the incision) I have tried so many fading creams, etc. Can a scar be revised and I will stay out of sun for 2-3 years and always apply sun screen, or will permanent tatoo be able to cover dark freckles on incision line? Who would think that the sun actually gets to that part of the body! Thanks for any information.
