Acne vulgaris

• Acne remains one of the most treated inflammatory dermatosis diseases worldwide. It has a complex pathophysiology: an interaction between hormonally stimulated sebum production, abnormal keratinization of the pilosebaceous duct, and an immune response. Acne affects an estimated 9.4% of the world’s population,19 and is the eighth most prevalent disease worldwide.(1)
• More than 5.1 million Americans sought medical treatment for acne in 2013. Acne affects primarily the young population and has a significant impact on productivity for affected individuals. In 2013 (2)
• Acne patients who sought medical care were primarily children and teens under the age of 18 and young adults between 18 and 44 years old.(2)
  Acne resulted in nearly $400 million in lost productivity for patients and caregivers in 2013 — comparable to the productivity cost of skin cancer. (2)
