Acne
"I&#039;m a Black woman who has mild acne (closed comedones on forehead and cheekbones), oily/combo skin, prone to post-inflammatory hyperpigmentation. I began using Biacna (equivalent to Ziana) regularly in November or December of 2016, once a day at night, making sure to apply at least SPF 40 every morning. It is now May of 2017, 5 months later, and my mild acne has spread all over my face - my forehead, all of my cheeks, and my chin are regularly covered in tiny bumps, and when those resolve, they are replaced with more tiny bumps. I think it is safe to say that this product is not working for me, since my acne has only gotten steadily worse over time, with no improvement. I will use this product for one more month."
