Curing acne can be either short or long process. But getting rid of smoking habit is usually a long process that at times does not end. However the combination of these two can destroy you.Acne implies the poor health of the skin. It is the excretion of inner toxins. It is the method by which the body tries to throw out the waste matter. If you continue smoking while suffering from acne, you are already trying to dump more toxins in the body, while it is making genuine attempts to offload the existing toxins. This will sabotage its efforts to heal itself.
