Perioral Dermatitis: 'Peri' means around, 'oral' means mouth and dermatitis means rash. So basically a rash around your mouth that no one knows how to cure. But that is what the doctors called it so after years of trying to naturally heal it I went to a dermatologist. The antibiotic cream (Metronidazole .75%)burned my face to the point of blisters.(spot check please! if you are considering this) The oral antibiotic (Doxycyline) gave me a new rash on the only part of my face that didn't have a rash. Then God saw fit to bless me with help! Zi Zai. I finally stopped denying my rash had a name and looked up Perioral Dermatitis. I found Zi Zai. The owner, Diana Hermann, suffered from this and so I thought 'what could I lose trying her products?' She recommended the Acne serum, toner and cleanser for my specific problem. She told me to give it two weeks. In two days, my rash had gone from red, bumpy and scary to calm, smoother and less itchy. It has been 6 weeks and a Doctor, a massage therapist, my mother and sister have asked for information about Zi Zai solely based on the improvement they saw on MY face. All I wanted was my rash to go back to the original rash (before burns and side effects of antibiotics). But now my face is so healthy, that I can actually go without any makeup! Diana said it won't cure and she was right. I'm still trying to purify my diet and research this 'thorn'! But I am so excited because after money flushed on so many products, I have found one that not only works but is making my skin healthier every time I use it. Dianna has also been so amazing in returning my requests for advise. She is passionate about her product because she knows it works. She really cares about people. And she is so willing to help educate you. My search for topical facial products is over. Whew!
