Hello sir I am a boy of 21 age boy with 52 kg weight I have problems with face that I have little white types of pimple that don't go fastly that stay for long time into the skin it don't hurt or ache but it stay little bit. Usually they are not like pimple that ache to the skin but they stay and go after long time as 2 and 1 year. What should I do for that. Please tell also my face skin seems to dry and weak.
