Hi doctor, For the past year my skin has turned very dusky,I used to be very fair.There is nothing I can pin point as to what is causing this.I live in europe so tanning is not the problem.However, the only thing I can think of is I moved country from ireland to england about 1year ago . Where i lived in ireland was a region of hard water and now I have to an area of soft water, can this change in water be the reason ? Regards, Amina
