This red macule is not a scar, and is not permanent. In a dark skinned person, the macule may appear as a darker patch on the skin. This is not a scar, either. Acne can be successfully treated in all cases. Without treatment the results can be heartbreaking, both psychologically and physically.
People simply hate the way they look with acne.
To one degree or another, people with acne often withdraw from life. Until recently, these psychosocial effects of acne have not been fully appreciated. The permanent, disfiguring physical scars of acne have the same psychosocial effect on people as the acne. Such people carry both the physical and emotional scars with them for their entire lives. While there is no way to predict how bad someone's scarring will be, clearing the acne prevents scars from happening.
