Hi, 5 weeks ago i was prescribed the contraceptive pill known as Yasmin to help with my mild acne & oily skin as nothing else worked. Since then my acne has completely gone but i still have oily skin. When can i expect my oily skin to get a bit better? The doctor said to go back after 3 months but did not say when my oily skin would improve. Also a few weeks before my skin got super oily i stopped eating dairy and swithced to soya. Do you think this could be the cause of my oily skin?
