"i took doxycycline for about eight months. it was working great and significantly cleared up my face (though not completely). my doctor took me off it because you can develop a resistance to it over time and it also makes your skin more sensitive to sunlight (although i felt at that that point it was still working fine). now about two months after being off it my acne has come back with a vengeance, it&#039;s almost as bad as it was before i took it. it is soul crushing to look into the mirror and see your skin become worse again. before you take it it is important to realize it is only a temporary fix and to be prepared for it to come back after you stop taking it. o acne thou hell o&#039; a&#039; diseases"
