As for simple antibiotics, they too kill bacteria in the beginning. But in the long run theyâre even worse, because the p.acnes bacteria is becoming resistant to them. The most common antibiotics used by acne patients over the last 30 years are erythromycin, tetracycline, doxycycline, and minocycline. Like any antibiotic they are specially targeted to kill bacteria and originally they killed p.acnes wellâ¦.

Using over-the-counter pore-cleansing strips, researchers from Los Angeles Biomedical Research Institute and UCLA lifted P. acnes bacteria from the noses of 49 pimply and 52 clear-skinned volunteers.
