Hi, i am 32 years of age,i am an asian origin and i am from Nagaland,india , my skin colour is pretty fair from my neck down but my face is dark and dark patchy(like pigmentation),i drink like almost all night(a quarter to half a bottle of Alcohol)) but i don't smoke and i use some tobacco every day (which is very common in India) Coul'd this be the reason that my face is getting darker?
