I am thirty now and have been lucky so far that my face is "youthful". I have a couple of deepening horizontal lines on my upper forehead that I am considering filling. Also, I have a "bumpy" forehead. Nothing Wrong with my skin, this is just the cranial bone. I have a long, unnoticeable "dent" between my brown bones and the top of my forehead. I wonder if fillers would help this? I don't want to look noticeably different. I've angled the photo so that shadows show where this dent would be!
