Hello Doctors, I am 25 year old boy, i am have became very dark now, but i was not born dark as such, there started a change in my complexion after attaining 12-13 years of age, and since then it has started growing, i was pretty fair during my childhood, people who met me after few years were now able to recognize me either, i have never taken care of my self at all, i always had a conception that taking care of your skin doesnt suits to a man, but now i have became very dark with no glow in my skin, i cant even remember applying a face cream or sun block either. i have also started smoking now, can you please help me out on how to get back my initial complexion, i will change any of my habit in this regard and will try to use any thing, Please help me out ?
