"i have been on biacna (canadian ziana) for about a month now. for the first couple weeks my skin flared up like crazy and my face was peeling. now i am finally starting to see my acne, which varied from cysts to moderate, disappear. i am hoping once my face becomes completely clear to see my acne marks fade. important: do not use any astringents or lemon/citrus or benzyl peroxide or tea tree oil while on this because it counteracts the chemicals in biacna. good luck and keep going xx"
