Hello Doctor, I'm suffering from pigmentation in various parts of my face like around the lips and neck. Recently I consulted one dermatologist who suggested me to apply kojitek on affected areas whereas i feel it's not making much of a difference. I stay in a pg so cannot restrict or be specific about my diet. I drink approximately 2-3 litres of water and go for a walk for 30 mins. Please suggest where I can see results abit early. I want to have a clear and gloat skin!!
