Accutane can help in reducing the appearance of blackheads, enlarged pores, and oily scalp by reducing the production of sebum. The beneficial effects of the medication may take several weeks to several months to become noticeable in most patients. Typically, Accutane is taken for several months and once the treatment is completed, most people do not need to resume it. While it is not guaranteed that acne will completely disappear after treatment, Accutane should greatly help in managing it. Acne may persist for some people for many years or never completely disappear, but its severity tends to decrease with age.
