Like other tetracycline antibiotics, Dynacin reduces the ability of bacteria to make proteins. Dynacin does not directly kill the bacteria; however, by inhibiting protein production, it reduces their ability to grow and multiply. This gives the immune system a chance to fight the bacteria.
The exact way Dynacin works to treat acne is unknown. The medication likely slows the growth of the bacteria that cause acne. It may also reduce inflammation, decreasing the amount of red, inflamed bumps and pimples.
