Hello doctor.i don't have any specified problem regarding my face.i am 18 now.i have a brownish face complexion,neither dark nor light.also 5 years ago I had a severe chicken pox,so it's marks are still on my face.during my pre-primary school days I used to play a lot outdoors.since I was child that time I didn't noticed that sun is affecting my face but now I observe that my face is darker than other body parts like arms,chest etc.few days before I heard about cream DEMELAN.i explored it on net.it had a good review.but I still feel to consult a doctor before trying it.so please detail me whether I should use it or not.and if yes then how to use,considering it's side effects too.do answer me please.thanks
