Oily skin frequently comes with complex problems such as acne, breakouts, clogged pores, dull skin, and yes, dehydration. Proper cleansing, as well as proper moisturizing, is essential. Your skin tends to produce more oil if it lacks moisture, thus more complication occurs. So gentle yet effective cleansing followed by good moisturizing will eventually balance out the skin. Another thing to remember is religious sun protection because excessive sun exposure often leads to more sebum production.
