Advice about skin care?

I have a mixed of oily and dry skin.
(My forhead and nose are oily and my cheeks dry).
A few weeks ago I've started to think more about the fact that I don't have any skin care routine and therefor my skin looks oily and dry and doesn't feel good.
Do you girls have any advice for me on how to take well care of my skin?
Thank you for taking your time reading this question and for the answers that may come:)~
