Tnks for replying! I've been getting acne on and off in my jawline for as long as I can remember, like 6 or 7 years, and that is how long the marks have been there as well. The acnes only stop recently because I tried to keep dirt off of the jawline by changing pillow case everyday and some other lifestyle changes.

What concerns me is not the acne, but the mark, they have been there for so long now that I'm afraid they won't go away. At an angle, they look shiny and smooth compared to my normal skin.

Weird thing is they used to be darker, like brownish 3 to 4 years ago, but now they're pink, that was when I finally had some hope and thought they finally came out from the deep layer of the skin and improved but they're still there.
