Doxycycline
"I've barely had any acne in the past then in just 2 months my face broke out like crazy and won't stop. its starting to bring my self esteem down like crazy, my acne is hormonal and my whole cheek is pigmented. I looked at the reviews and had high hopes for this medicine. I've been on it for about a month by now and I am seeing no changes. My derm told me it should be a lot clearer in about a month and less inflamed, well its not any less."
