A note from Vivian Tam

“We don't want you to come back.”

An honest letter about how Zilch started, what to expect in your first eight weeks and why we built the business the way we did.

To be truthful, most brands are built on customers buying the same product every month for years. We designed Zilch Acne Formula to target the root cause, so once you are happy with your skin, you can stop buying it. (Not exactly a great business model now that we’re thinking about it!)

For more than 17 years my work has been with skin and hormonal health. Zilch Acne Formula was originally developed for in-clinic acne patients, the people whose skin had not responded to anything else. And I tracked its results over two years, and the success rate was astounding.

When I launched it online in 2017, I was terrified. I had put most of my savings into it. That first night we sold 12 bottles, and two of those were bought by my husband and my brother. (Love you guys!)

My brother told me, "If you focus on truly helping people, the rest will sort itself out." He was right.

"Faceless brands have nothing to lose. I would never launch anything I didn't know would work."

Three things I want you to know first

It takes a few weeks. Most users notice inflammation and redness calming within 2 to 3 weeks, with more significant improvements from week 4 onward. Some people have a short adjustment period at the start. It is mild and should resolve within 7-10 days.

It works from within. Topicals work on the surface. The deep, sore breakouts along the jaw and chin tend to start from the inside-out, which is where the formulation of 17 Chinese herbs are aimed.

No product works for everyone. We’re a no-gimmick brand, so honesty is at the core of who we are. It is why we have a 60-Day Clearer Skin Guarantee. We’re so confident that it’s worth trying, that if you don't see improvements within 60 days, we'll refund your purchase (when you start with 2 or more bottles).

Amazing results

I must admit I was super skeptical when a friend recommended this to me for my hormonal acne, however the results speak for themselves! So impressed!

Helped even my skin

The price is expensive but it is worth it. I've struggled for years with acne and this has helped! Whilst I still get some small spots it has calmed them down.

Amazing results!

I am nearing the end of my first bottle and have been so impressed! I am experiencing way less breakouts, the redness has soothed almost completely and my skin looks and feels so much smoother in just a few weeks.
