Zilch was created by Dr Vivian Tam, a Doctor of Chinese Medicine in Melbourne and a recognised expert in Chinese Medicine dermatology. She originally developed the Acne Formula for her own clinic patients, then turned it into a product so that people who can't get in to see her could use it too. The formulas are 100% Chinese herbal ingredients with no fillers, binders or preservatives, and they're vegan and cruelty free. The range covers the Acne Formula, a PMS and Stress Formula and a Digestion and Bloat Formula. I had Vivian on my podcast, and she is an incredible practitioner with real results behind her range.
