Hi doctor, I can notice that my health condition is bad when compared with one year back. I'm feeling like my body is surrounded by dirts in my neck there is a black layer formed due to dirt even though I bath daily and I used to rub it but it is not cleaning and my face also looks dull it should be glowing in this age right? What can I do to get over this problems and how to keep my face glow? My face is very black compared to my body!
