For the last few weeks, I have had a crop of spots under chin and along jaw line. I hardly ever usually get spots at all but this lot are persistent- when one goes, there's another to take its place. I'm 31, use Mirena coil but have had that in for 18 months so no change in hormones recently, and haven't changed diet in recent past but did stop smoking nearly 4 weeks ago.
Any thoughts on causes or treatments?
TIA
