I have been to the dermatologist about white halos that have developed around my moles (quite a few). There are even two spots on my head where even the hair lack pigment. Granted these are small spots but together it is quiet noticable. I believe it is called Halo Nevus? My question is: what are the chances repigmentation will occur and how long will that take?

i have about four keratosis i think i am over 60 does anyone know how to
get rid of them and how many can you get.
