In this episode of Skin Anarchy, Oliver Liu, co-founder and CEO of Hypothesis™, takes us deep into the science of the skin microbiome—moving beyond the oversimplified narratives that have dominated skincare conversations for decades. What emerges is a clear disconnect between what science now understands about conditions like acne and eczema, and the treatments still widely used today.

At the core of this conversation is a fundamental realization: we still know very little about the microbial world. Despite the explosion of interest in the microbiome, an estimated 99.9% of microbial diversity remains unexplored. This means that while the beauty industry has embraced microbiome language, it has not yet fully translated that knowledge into meaningful, targeted solutions.

The Real Drivers Behind Acne and Eczema

For years, acne and eczema have been framed broadly as “bacterial conditions,” leading to treatments designed to eliminate bacteria altogether. But modern research paints a far more nuanced picture.

In eczema, the issue is not just inflammation or dryness—it is a cycle driven by three interconnected factors: a weakened skin barrier, an overactive immune response, and a microbiome imbalance. Central to this imbalance is Staphylococcus aureus, a bacterium that doesn’t simply coexist on the skin but actively worsens the condition. It produces toxins that break down the skin barrier, amplify inflammation, and even directly trigger itch through interactions with nerve cells. This creates a self-reinforcing loop where irritation leads to scratching, which leads to further damage and inflammation.

Acne follows a similar pattern of imbalance rather than simple overgrowth. While Cutibacterium acnes is often blamed, it is actually a normal resident of healthy skin. The issue arises when specific inflammatory subtypes dominate the population. These strains produce more irritating byproducts, disrupt sebum balance, and trigger inflammatory cascades. In other words, acne is less about the presence of bacteria and more about which versions of those bacteria are in control.

Why Traditional Treatments Fall Short

Despite these insights, most treatments remain rooted in a broad-spectrum approach. Ingredients like benzoyl peroxide and antibiotics are designed to eliminate bacteria indiscriminately. While they may reduce symptoms in the short term, they also disrupt beneficial microbes that play a critical role in maintaining skin health.

This creates a paradox. By removing harmful bacteria, these treatments also remove the very organisms that keep the ecosystem balanced. Once treatment stops, the skin is often left more vulnerable, allowing harmful bacteria to return—sometimes more aggressively than before. Over time, this cycle can lead to increased sensitivity, compromised barrier function, and even antibiotic resistance.

The issue is not just inefficiency—it’s misalignment with how the skin actually functions as a biological system.

A Shift Toward Precision Skincare

What Oliver and his team at Hypothesis™ propose is a fundamentally different model: precision targeting. Instead of attempting to reset the microbiome through destruction, the goal is to selectively remove only the harmful bacteria while preserving the rest of the ecosystem.

This approach is inspired by naturally occurring enzymes called lysins. Found in nature, these enzymes are designed to target specific bacteria with remarkable accuracy. They bind to the cell wall of a particular species and break it down rapidly, leaving neighboring bacteria untouched.

The concept is simple but powerful. Rather than “carpet bombing” the microbiome, this method acts more like a surgical tool—addressing the root cause without collateral damage.

The Challenge of Making Precision Real

Translating this idea into a viable skincare solution is far from straightforward. Achieving true specificity requires identifying enzymes that can distinguish between nearly identical bacterial species—such as harmful Staphylococcus aureus and beneficial Staphylococcus epidermidis. It also requires ensuring that these enzymes remain stable in real-world conditions, from formulation to shelf life, and can be produced at scale.

After years of research and testing hundreds of variations, Oliver’s team developed enzymes capable of eliminating over 99.99% of their target bacteria without affecting beneficial microbes or damaging skin cells. Just as importantly, these molecules are gentle and non-irritating, addressing one of the biggest trade-offs seen in traditional treatments.

A New Framework for Skin Health

What makes this conversation so important is not just the technology—it’s the shift in perspective. Acne and eczema are no longer being framed as problems to suppress, but as imbalances to correct.

Instead of asking what product can “fix” the skin quickly, the question becomes: what is disrupting the system, and how can we restore balance?

This shift moves skincare away from reactive solutions and toward a model that is aligned with biology. It recognizes the skin not as a surface to treat, but as a dynamic ecosystem that requires precision, not force.

Where the Industry Is Headed

As microbiome research continues to evolve, it is becoming increasingly clear that the future of skincare lies in specificity. Broad-spectrum approaches are giving way to targeted interventions that respect the complexity of the skin rather than overriding it.

The work being done by Hypothesis™ suggests a future where treatments are not only more effective, but also more sustainable for long-term skin health. It is a move toward understanding rather than overcorrecting—and one that may finally close the gap between scientific knowledge and real-world skincare.

This episode makes one thing clear: the era of “kill everything” is coming to an end. What comes next is precision.
