you might be having a combination skin, where in the T zone that is forehead, nose and chin might be oily and rest of the areas might be normal or dry. To prevent blackheads and pimples
, use a mild face wash like cetaphil
follow it with a toner and then use a water based moisturiser. Get your blackheads extracted whenever the need be or you can simply scrub your blackhead prone area and use an extractor to remove the superficial blackheads. As far as the dryness of your body is concerned, use a glycerine based soap or medicated soaps meant for dry skin
. Simple dab your skin with towel and apply a moisturiser meant for dry skin like elovera or venusia immediately. If you will apply a moisturiser immediately after bath it will be more beneficial. Take care.
