Are there any ways to stop my skin from getting so oily half way through the day?

You can start with: a foundation and face powder for oily skin if you use them. Interestingly, sometimes drying the skin out too much with washing & toner etc. can cause some "rebound" oiliness. Using mild soap and a mild, alcohol free toner may actually help. Most make-up removers are oily so I recommend mild soap for make up removal as well. Dr. Anne
