I have some recommendations for you.
I am the person who has oily skin in the summer, but in the winter, I have dry one. So at first, I was confused by this kind of skin. But now I know the treatment.
For oily skin, you must apply on Vitamin E cream every night before sleep. Don't think This cream can cause much more oil. because it do not do any thing but protect your pores and keep the oil level stably.
And you must steam your face above hot water, in the distance that comforts you the most. This action contribute to prevent acne (because oily skin in face is one of factors cause acne)
Must drink more water too.
