I'm a 24 year old female that has been battling acne for about 10 years. I have comedonal acne, caused by my skin not shedding dead skin cells causing clogged pores. My zits are never red, they're all very small and skin colored. It's still embarassing when I look in the mirror. They don't show up in pictures with good lighting so I can hide it most of the time. I started Ziana two days ago. Applying a pea sized amount once at night, I apply Cetaphyl SPF 15 moisturizer on about 30 minutes after applying Ziana and in the morning I use Paula's Choice 2% Salycic acid BHA gel. Will update you on how it goes..
