How do y'all keep clear skin?

Sarah

How do y'all take care of your skin and keep it clear? I have been to the dermatologist and she continues to put me on the same medication even though I tell her it's not working. I eat healthy and drink a gallon of water everyday. I also wash my face 2-3 times a day (3 bc I play softball) and exfoliate twice a week. Help please.
