solved this, don't want to keep it cached

umm im assuming your male since your shaving your chin...
if so settle yourself in dude your facial hair is only going to get thicker and the only way you can get rid of it is by doing what the rest of the male population does.. Shaving every time it needs shaving.

No no, I am shaving it every other day, but the skin above my lips is grayish/lighter than my cheeks, so it looks like I have a stubble ("5 oclock shadow") but it's only above my lip, not on my cheeks, maybe I just need to get out in the sun more?

yeah if its thick hair and its always unshaven its going to be lighter than exposed skin, just shave it everyday and get more sun
