Acne is a chronic skin disease involving inflammation of the sebaceous glands. It usually appears on the face but can also appear on the back and chest. It affects 80% of teenagers and many adults, especially women, 35% being between the ages of 30 and 40. Acne represents 15-20% of consultations in dermatology.
Acne is a chronic, recurrent disease that requires initial treatment, as well as maintenance therapy. Initial treatment is based on topical retinoids alone or in a combination with topical and/or oral antimicrobials (topical benzoyl peroxide, systemic antibiotics), depending on the severity of the disease. The most severe form is treated with oral isotretinoin. All patients should use maintenance therapy, which includes topical retinoids.
