why does it take forever for a socre to disappear from my skin? if get a pimple or a cut or any skin relatd injury it will take close to a month for the area to vanish of having any injury. i got burned 2 months ago and it is on my leg it is still purple, no scap or anything but still there, or pimples, they are like leaving scar marks on my face, not going away, i dont get it, i do have chronic highpertension. and is being treated.
