Hi Poppy, I've been having good and bad days. After I returned from holiday pigmentation was dark due to the sun. It took a while before it turned slightly lighter. There are days when I wake up and look in the mirror and it appears less dark than usual and other mornings it looks like I've got a real dark tash!!! It's crazy! I'm going to order some benoquin cream and give that ago and see if it makes a difference. I really wish it would just fade. Will keep u updated. I think it would be good to change desks as the sun beaming on your face will not help even with sun factor and the cold weather.
