wash the affected area with a mild cleanser and make sure the skin is
completely dry afterward. Apply a small amount of gel, 20 mins after washing, to the entire affected
area/s each evening and rub in. If the gel does not easily rub into the skin
then you are using too much. You should wash your hands after each application.
Allow the gel to dry on the skin, do not wash it off.
Benzoyl peroxide, an active ingredient in Duac, can have a bleaching
effect, so avoid getting it on your hair or clothes.
