I have a small indent around my hairline. I noticed it a few years ago and at my regular dermatologist check it has never changed and continues to just be one of those unexplainable things. Last week went for another routine skin exam. Noticed two more indents in my forehead, pretty much along the crease line. Since these indents are new, dr recommended a biopsy. She says she isn t overally concerned. But needs the biopsy to detine what it is. She mentioned that these could be old acne and or chicken pox scars. They were well hidden so far, but as we get older skin loses elasticity, making scars look more noticeable. Any thoughts?
