Cystic acne is a severe form of acne that involves large, painful, pus-filled cysts beneath the skin’s surface. It is often caused by hormonal changes, particularly during adolescence, and can also be influenced by genetics. Treating cystic acne typically requires stronger interventions such as oral antibiotics, hormonal treatments, and isotretinoin. In some cases, dermatological procedures like cortisone injections or laser therapy may be recommended. Early and aggressive treatment is essential to prevent scarring and manage symptoms effectively.
