Hello Angelina and welcome to HCM. Oiliness of face is dictated by several factors like genetics, hormones, pore size etc. Pores are natural outlets to drain out the sebum or oil which is produced within skin in sebaceous glands. In people with oily skin these pores are enlarged and clogging of such pores can lead to acne frequently. Since pores are natural structure of skin, they cannot be removed but there size can considerably reduced which in-turn will also reduced oiliness of your skin. Apply a pea-size amount of tretinoin gel 0.025% gently over full face every night. Use water-based moisturiser like Emolene cream to keep skin hydrated. Avoid excessive and vigorous washing of face. Use a salicyclic acid based cleanser twice a day to cleanse the face.(Saslic facewash). After cleansing you can also apply a good toner with cotton to cleanse your pores thoroughly.(Sebamed clear face deep cleansing toner). I am sure with the above regimen your pores size will decrease considerably and thus the oiliness. Let me know if you require any more assistance from my side. Thanks Dr Hardik Pitroda
