"i had moderate acne and frequently got cystic acne due to my extremely oily skin. the cystic acne was so deep and painful that i asked my doctor about what to do and she perscribed me this. i swear it works miracles! my acne was virtually gone after 2 weeks, and my ultra oily skin felt normal and smooth! even though the box says it only helps acne vulgaris, benzaclin really works on cystic acne as well."
