I have had a few similar looking spots on the tops of my hands before after tanning that later turn darker brown
, than lighter brown
, then the disappear. This is also happening with the spots on my forearms. They went from red/purplish, to dark purple, to dark brown, and now they look like they are fading (currently light brown). I am assuming they will disappear as the ones on the tops of my hands have in the past.
