I think if you have lighter spots in ur skin it means it didn't get to sun exposure because it was covered by your hair or beard . But I think u don't have skin problems
the discoloration isnt lighter its pinkish and darker. And like... none of that area has been exposed to the sun its not like a tan or anything..
Can you tell me which part that is discolored?
its there in the picture. the more reddish/orange splotch.
