Acne is started as pimples (or some called it zits) and then for long time it has not been healed it developed into an acne. Just like an image below. Such woman (guess who this woman is?) has a chin pimple. If you enlarge it (through clicking any image you like to make it big), you will see more if it is not that visible to you now. I am not a doctor, dermatologist or such doctors alike but I know what pimple is and talking about what I said, I observe it on myself. I am just talking about general term that when an acne would not be healed, surely it will develop an unpleasant physique especially if it is located in any visible to a person's eye. Hence,  acne treatment that works which is reliable, proven and tested is essential during this time of period, so it won't develop unto more acne.

What do you think, do I make sense? You know that being tidy is one of the requirement of a pleasing personality. So when someone is concern of his/her physical appearance, he/she makes sure that pimple should not be taken for granted.
