Hi, Thanks for writing to us. To treat your dull and oily skin, you may follow these suggestions 1) Use a salicylic acid or glycolic acid based face wash twice in a day 2) Use a sunscreen with good SPF in morning meant for oily skin like suncross aqua gel or photoban or ultraguard etc. Even shadowz sunscreen is a good choice. 3) Use a water based moisturiser. Even oily skin needs hydration. Neutrogen, clinique, sebamed etc have some good moisturisers for oily skin. 4) Use glycolic acid kojic acid based cream like rejuglow or kojivit plus cream. 5) if possible take few sessions of chemical peels like salicylic aicd peel. This would reduce your oiliness as well as improve complexion. 6) Once in a week, scrub, steam and apply a cool mud mask over your face to unclof pores and absorb excess oils. Hope this helped. Take care
