I've been applying Epiduo for about 6 weeks now and I recently had my appointment with my dermatologist. He said that it slightly improves acne. When I first started Epiduo, even my face wash was irritating and burning my face when applying but it hasn't anymore. I still have flakiness and dryness around my mouth area and jaw line. My acne is still red and irritated. I don't see much improvement at all but my dermatologist recently put me on Doxycycline and I'm taking 100mg twice a day. My face has recently gotten dry again with the burning sensation on my face when put a cleanser on, just like when I first started Epiduo. How long is it still results show and has this happened to anybody else?
