"this is amazing. i was prescribed benzaclin after my doxycycline stopped working.  the first night i applied this, i had multiple zits on my chin including a large cyst-like pimple.  normally my cyst pimples can take several weeks to clear up.  the next morning that i woke up, the redness and size of all of my zits were visibly smaller, including the cyst. 3 days later, although a little dry, my chin is almost cleared up. i just add a little moisturizer after the medicine dries and i apply makeup and my confidence is back. i have not experienced any burning or stinging like i have read in others&#039; experiences.  i only apply to the affected area, not the whole face.  i highly recommend this product."
