Isotretinoin is a strong medicine that is reserved for treating severe acne.

Acne is caused by an overproduction of sebum, which in turn causes the sebaceous glands to become clogged and inflamed. Although acne can affect people of all ages, it is most common in adolescents. Most of the time, the spots will fade with no need for treatment. Sometimes, however, the impurities are more severe. Cysts and abscesses can form on the skin, which can be very painful and unattractive. These types of acne are referred to as acne conglobata and acne cystica.

Acne is usually treated with a topical medicine such as an anti-inflammatory cream or lotion, or with antibiotics. Isotretinoin is used for acne that hasn’t improved with standard treatment involving antibiotics and topical medicines. It works by reducing the production of sebum in the skin and slowing down the growth of skin cells in the epidermis. As a result, the skin regenerates more quickly and pores become clogged less often. Isotretinoin also reduces inflammation and the growth of acne bacteria.
