Acne vulgaris (acne) is the most common skin disorder, affecting more than 80% of adolescents, although it may present at any age. Treatments for acne include topical (benzoyl peroxide, retinoids, antibioitics, azelaic acid) and systemic agents (antibiotics, zinc, hormonal therapies, isotretinoin), laser and light sources and combination treatments. The therapeutic approach to acne based on the European guidelines depends on the severity and type of acne (mild, moderate, severe acne; comedonal, papulopustular, nodular and conglobate acne). Also, the treatment of special age groups such as in childhood or adult acne requires special consideration.
