hello, over the past few years, I have noticed a loss of pigmentation on my genitals. As you can imagine, it is extremely embarrassing. It has encomposed around 20% of the scrotum and small patches on the penis. It is offwhite in color. I haven't noticed it growing at all in the past couple of years, and thus did not find it necessary to go to a doctor about it. I also have a very small patch of pigmentation loss on my face too, but it is not nearly as large as the other region. My question is, what could it be? and if there is any over the counter treatments available.
