Can We Define Acne as a Chronic Disease?If So,How and When?

There is widespread misunderstanding of acne amongst both the medical and lay community, who often perceive the condition to be a simple, self-limited affliction of adolescents. Because many think that the disease “will go away on its own,” they do not feel an urgency to aggressively treat acne. However, very often the reality is that acne treatment can be quite difficult. Furthermore, acne can be a devastating disease for the patient, since it manifests on visible body parts and in children near puberty, who are vulnerable both socially and psychologically. Most typically, acne is not an acute disease but rather a condition that continuously changes in its distribution and severity. Usually, acne treatment is necessary for many months and sometimes years. Despite treatment, acne may cause scarring and associated negative psychological effects. It is important for both patients and physicians to be aware that very effective treatments are available. It is also important to realize that new studies have proven the benefit of maintenance therapy with topical retinoids; these agents can minimize the potential for relapse, which is part of the natural history of acne. This article reviews the evidence suggesting that acne is a chronic disease in at least a subset of individuals. The members of the Global Alliance to Improve Outcomes in Acne believe that acne should be recognized and investigated as a chronic disease. This will change expectations of clinical trial design and treatment and will highlight gaps in the knowledge of acne epidemiology. The result should be an improvement in patient outcomes.
