besides a bunch of normal ones that are older and have turned white, i have a very deep and red one that is very sensitive. i believe the right word is hypertrophic or keloidal? well its raised, dark and hurts to touch. can i have it lasered anyway? would it go away? will lasering them even make them go away at all or will they just fade a little? will i ever be able to get a tan in the summer without looking like a zebra with shiny stripes all over my arms? thanks for any advice!
