I just finished taking it for 3 months. I was prescribed it for perioral dermatitis, which it cleared up really well, but my normal acne not so much. Took forever to start doing anything for my acne, barely helped it at all actually, and now since coming off of it, my skin is kind of getting worse. Acne spots are super red and taking forever to heal, like seriously ive had this one spot for like 3 weeks, its trying to heal but just wont. Doxy is just a huge useless waste of time i think..
