I've recently starting using Pixi Glow - I soak a cotton pad in it and gently wipe my face with it every evening. I recently change contraceptive pill too which had led to some hormonal breakouts on my chin so I started to use Pixi on my chin in the mornings too.
I'm noticing though that not matter how clean my face is, when I wipe my chin with a pad it always looks dirty 
For example yesterday I washed my face, put on a face mask, washed it off and rewashed my face, patted it clean with a clean towel then used a pad soaked in Pixi on my chin and it came away dark with dirt.
I've even tried it in my DH's skin to see if it's just the pads or Pixi but his was completely clear (cue mortified me).
Why is my skin so dirty?
