Yaz , like all BCPs , do cause fluctuations in your hormone levels for 3-4 months when you first start them and also when you first end them. During this 3-4 month period, acne flares also as your hormones fluctuate but not as much as other BCPs, then acne improves in most patients and stays calm for a long time. Good Luck, David Hansen,MD
