hi i would say the same as the others probally due to oily skin try using a face scrub for oily skin dont use to much moisturiser try and find one that is suited to ur skin type. i find the clean and clear for oily skin range is great but everyone is different.try keeping ur hair out of your face as this can cause oily skin and drink plenty of water and get plenty of fresh air.oily skin is nothing to worry about as it is just your skin type that can be managed.hope this helps.
agree with wishforanswers,but i was like it when i was pregnant too.
Usually shine is caused by oils in the skin.
