About zilch® Formulas

A little about us

Why zilch® Formulas?

zilch® Formulas exist to offer real solutions that are truly all natural. There are a lot of products out there that are “clean and natural” and upon research, they reveal themselves to be far from that. Similarly, a lot of products promise results, but are all smoke and mirrors. We’re here to change that:
zilch®– Nothing to hide.

Results focused.

With so much out there, it’s hard to know what really works–especially for acne. At zilch®, we have worked tirelessly to formulate products that make a real difference. We would never add a product just to release something new–it needs to work and get real results, not bandaid solutions. Our reputation lies in the results and we would never do anything to compromise that. Realistically, we won’t ever say that something can work for everyone, but we are proud to say that we get pretty close!

Authenticity is key

What you see is what you get.

Being authentic is our most important core value. We promise this: 
• All our reviews are genuine
• All of our before and after photos are untouched, unedited, and sent in by real users
• All our ambassadors have real skin journeys, and their content is never scripted
• Our formulas have been formulated by leading doctor of Chinese Medicine, Dr. Vivian Tam. Our products have a real face behind them! 
• zilch® is a small and passionate team in Melbourne that actually care.

We stand behind this: zilch– Nothing to hide.

All natural, always.

We are all natural, 100% of the time. Our formulas are made up of only herbal ingredients + potato starch as a binder. Really! Our unique and specialised production process is allows us to add no binders, no fillers and no preservatives. There’s nothing else on the market like it and we are so proud to be able to produce our pure herbal extracts in tablet form with no nasties!

Our mission

To help everyone achieve real results without the use of harsh chemicals or drugs. We want to build a community that can say no to harsh ingredients and turn to nature to heal.

“I suffered from acne as a teenager and went through the typical pubescent frustrations with my skin. These skin issues bothered me all the way into my 20’s with no luck in finding a real, long term solution to my skin problems. When I started working as a Doctor of Chinese Medicine, I had access to all the Chinese herbal ingredients my heart could desire (yes, herbs are kind of a love and passion for me!). Within weeks my skin was almost completely clear, and years later, my skin is still in great health.

My father is a Doctor of Chinese Medicine doctor, so I grew up with the interest in it as a child, but this was what led me to focus on the skin health and dermatology side of things. Fast forward to today, and I am treating patients day in and day out with their skin issues and acne problems, helping them achieve their dream of healthy, clear skin. I could not be happier in what I do as it is so rewarding to be able to help provide a real solution to people that have tried everything without success. My passion in Chinese Medicine and skin health has opened up doors to create my dream product: Zilch Acne Formula.”

The creation of zilch®

The results in Dr. Vivian’s clinic were obvious: an over 90% success rate tracked over nearly 2 years in helping reduce and clearing acne in her patients. She had an effective solution and wanted to be able to help more people- people across Australia and worldwide, not just people that came in to see her at her clinic. So, overnight, the dream of an all-natural acne formula tablet, Zilch, was born. And the mission was simple: to help everyone achieve real results in clear skin, naturally, without the use of harsh chemicals or drugs.

Dr. Vivian Tam spent the next 18 months working on the formula and getting it approved by the TGA. When the formula was granted approval, the dream became a reality.

Dr. Vivian's "why".

Apart from wanting to share a real solution with acne sufferers, Dr. Vivian's driving force behind zilch® is to support animal welfare charities around the world, in an effort to make a change in the unnecessary suffering of animals used in tourism, factory farming and injured street animals. Dr. Vivian ties the growth of zilch® to the growth of a world that has less animal suffering and hopes to, in the future, fund a sanctuary for souls in need.
