I uses to be bit fair skinned but after joining hostel i got tanned in 1st year but later in 2nd year i started regaining my complexion but still the face was darker than other parts of body..but now in 3rd year even my upper half of neck is dark and my face is darker..is it due to sun or any other problem cause am in sun as much as any other person and others as far as i have observed dont have this problem..it is just me...also my skin is bit sensitive..so will this cure in course of time or..what am i supposed to do?
