"ziana is a great product. i have used it for 4 yrs. after years of suffering with adult acne and trying various dermatologists and products nothing helped! a friend referred me to her dermatologist. i was prescribed ziana and otc cleanser cerave. due to the cost i almost didn&#039;t buy it. the pharmacist gave me a pep talk and i purchased it. oh, i am glad i did! i returned to the dermatologist for a 6 week follow up. i was overjoyed with the results my face had completely cleared. the only  thing we didn&#039;t do was to take pictures before. i had no redness or worsen breakouts. i still use it for maintenance. a life changer and i highly recommend it to you. insurance didn&#039;t cover all of the cost but it was worth it. i thanked my pharmacist too."
