Honestly, you are being your own worst critic! I don't think that anyone - except you - even notices those small, evenly spread out, spots. In fact, it has the appearance of the shadows of hair follicles! Your head looks like what guys spend $5,000 getting SMP tattoos to get!
I have lots of spots on my head but mine aren't nice and evenly sized and evenly dispersed like yours are. Mine are "old man" or "age" or "Liver" spots. Once or twice a year a doctor friend of mine who operates a tattoo removal laser for another friend of mine goes over my head and hits the worst of them with the laser to break them up; but;
a. Even though he uses numbing cream and cold air - it hurts!
b. And they always come back.
c. It costs A LOT MORE than the skin bleaching cream that Tyler has identified in his post.
