In the last several years I have started to notice white dots / white spots on my skin - mainly in the area of the forearms and legs. In the beginning I was not worrying about them at all, there were only few of them, sometimes they were visible more, sometimes less. I am 30 years old now and started to worried as the amount of this white dots has hugely increased. They are completely flat, not itchy, sometimes I have got an impression they are visible more during a cold day, or that when I rub them they disappear for a while.
I am attaching few pictures of my forearm:
I would appreciate any help.
