My skin getting dull, darker and there is no glow at all as before. When I was at age of 16 my skin had natural glow and brighten skin tone especially my face. And I was strong, fall frenetic and so more. Which we have been calling as a good sign of health. But now I am 20 years old I fell depress and I become weak now and now, my skin has a darker tone even after I have been used sunscreen whenever I get out from home also I have definitely used to daily wash my face thrice in a day. And taking shower twice in a day. And I try to eat healthy as much as I possibly can. So what should I do to get that glow in my skin as before with brighten skin and fell frenetic. Please help me.
