Zero BS: Now Dermatologically Tested and Dermatologist Approved

The first (and only?) tallow-based skincare brand with both clinical trials and dermatologist backing.

Fact vs Fiction. Let’s Get Clinical.

In a world full of marketing spin and cosmetic BS, we’re proud to share a real, verifiable milestone:
Zero BS is now Dermatologically Tested and Dermatologist Approved.

As far as we know, we are the only tallow-based skincare brand in the world to back up its claims with both clinical trials and dermatologist endorsement.

Now We Have the Science to Prove What You’ve Been Telling Us for Years

For two years, we’ve received glowing feedback from hundreds of loyal customers. But now, we have concrete, empirical evidence to back it up.

Our clinical trials were:

• Run by a third-party lab

• Independently funded by a government body

• Aligned with Good Clinical Practice Guidelines (internationally recognised)

• Conducted with zero influence from us

These weren’t marketing-driven fluff tests. These were proper clinical evaluations.

Results: Zero BS Is Not Just Safe. It's Therapeutic.

The trials proved that Zero BS:

• Is non-irritating—even on sensitive or compromised skin

• Possesses anti-inflammatory, antioxidant, antibacterial, and antifungal properties

• Can be safely used on fragile, delicate, and reactive skin types

This officially classifies our tallow-based skincare as more than a cosmetic. It’s therapeutic.

How the Study Worked

• Human volunteers were tested (5% had pre-identified sensitive skin)

• Products were applied and observed at intervals: 0, 24, 48, 72, and 96 hours

• Study duration: 2 weeks

• Controls used:

  • Deionised water (negative control) scored 0.76 (non-irritating)

  • 1% Sodium Lauryl Sulfate (SLS) (positive control) scored 2.00 (irritant)

Now here’s the kicker:

Zero BS products scored 20% less irritating than even deionised water.
Yes—less irritating than water.

Our proprietary blend of essential oils actually enhanced the anti-inflammatory effect. That’s what happens when skincare is made with therapeutic intent, not fragrance and marketing fluff.

Let’s Talk About SLS

SLS (Sodium Lauryl Sulfate) is used as the positive control irritant in almost all dermatological testing. And yet?
It’s used in 90% of commercial personal care products—often at concentrations between 10% and 30%.

Why? Because it foams. And the industry has taught you to equate foam with clean.

We’re calling it: That’s the BS.

All Zero BS products—including our Soap, Shampoo & Shaving Bar—are 100% SLS-free.

More Than Skin Deep: Why Zero BS Works

Zero BS is not just another "natural" moisturiser. It’s a nutritional therapy for your skin, supporting:

• Skin barrier repair

• Microbiome balance

• Moisture retention

• Natural resilience against inflammation and infection

Because when you feed the skin what it recognises, it starts working for you.

Final Word: Backed by Nature. Proven by Science.

This latest clinical milestone isn’t just a tick on a box.
It’s proof that skincare made from real, whole ingredients can compete with (and outperform) the lab-made stuff.

If you’ve got sensitive, reactive, or barrier-compromised skin, you deserve better than industry-standard junk.

Zero BS is here to deliver it—without the fillers, irritants, or spin.
