And when anybody meets me say how do you became so dark. Now I came back to city started using facewash and even moisturizing cream and scrubs but its almost ten days but no change in colour. What shall I do what product shall I use. please help me is it possible to get back that skin colour and glow like before and how many days will it take. I do smoke here in city also. Need your help does even cold also turns your skin dark.
