Ive been getting these lines more and more on my face over a period of months, it started with one and now i have about five and they seem to pop out of nowehere??? they are indented and did not start off as pimples. theyre taking over the left side of my face, does anyone know causes or treatments?? has this happened to any of you and why?? My face was zit free for about 9 months and the lines still popped up.
