How Doxycycline Works For Acne

Doxycycline is prescribed to cure acne that hasn’t responded to other treatments. It controls the bacteria that cause breakouts, clears the pores, and prevents the infection from spreading. Acne is not contagious, but antibiotics like doxycycline can help clear acne by reducing the number of acne-causing bacteria (Propionibacterium acnes) present on your skin.

The antibiotic works on reducing the redness and inflammation caused due to acne vulgaris and other acute forms, including rosacea. But remember, it is not a spot treatment for clearing blackheads, whiteheads, or breakouts.
