You may have heard the term prebiotics in skincare, but what they actually do is often misunderstood.

So, what are prebiotics?

Prebiotics are nutrients that feed microbes.

On your skin, they serve as food for the organisms that make up your skin microbiome.

When the right microbes are supported, they help maintain a strong barrier, calmer skin, and better overall balance. But most skincare prebiotics—usually borrowed from the food world—feed microbes broadly and non-selectively.

Your skin microbiome is much more specific.

And that’s exactly why CeraBloom™ is different.

Meet CeraBloom™: A Precision Prebiotic Discovered with AI

CeraBloom™ isn’t a generic prebiotic.

It was discovered using our AI microbiome platform, which mapped the complex interactions between skin microbes and identified the exact nutrient that fuels the organisms linked to healthier, more resilient skin.

What CeraBloom™ does on your skin

CeraBloom™ feeds specific microbes on your skin—key organisms that naturally produce a diverse, skin-relevant set of specific and diverse ceramides.

These natural ceramides help:

Restore and strengthen your skin barrier

Reduce the appearance of redness and sensitivity

Re-balance your microbiome toward a healthier community

Improve skin resilience over time

And this isn’t theoretical. It’s clinically validated.

Backed by Three Clinical Trials

(including a nearly 80-person, 8-week randomized placebo-controlled study).
We know exactly what CeraBloom™ does on real skin because we tested it thoroughly:

✔ 3 completed clinical trials

✔ One of the largest prebiotic skincare trials conducted (~80 participants)

✔ Showed improvements in barrier strength, redness, sensitivity, and overall skin health

✔ Demonstrated healthier, more diverse microbiome patterns

✔ Confirmed CeraBloom™ increases microbe-driven ceramide production on skin

CeraBloom™ has one of the most robust evidence bases of any microbiome-focused skincare ingredient.

Why Ceramides Matter

—and why feeding the right microbes changes everything!

Ceramides are essential lipids that keep your barrier strong, hydrated, and calm. As we age or experience sensitivity, ceramide levels drop and the barrier weakens.

Most skincare products try to add ceramides from the outside.

CeraBloom™ works differently:

It helps your skin make its own ceramides—naturally.

By feeding the microbes that produce a targeted,diverse set of ceramides, CeraBloom™ supports barrier repair from within the microbiome.

Why CeraBloom™ Isn’t a Typical Prebiotic

Traditional prebiotics:

Feed microbes broadly

Aren’t designed for skin

Can support unwanted organisms

Deliver limited or inconsistent results

CeraBloom™:

Discovered with our AI microbiome platform

Feeds specific target microbes tied to skin health

Boosts natural ceramide production

Re-balances the microbiome without overfeeding opportunistic species

Clinically proven improvements in barrier, redness, and sensitivity

It’s the first prebiotic designed for sensitive and aging skin with real mechanistic and clinical proof behind it.

The Bottom Line

Prebiotics feed microbes.

CeraBloom™ feeds the right ones.

Discovered using AI and validated across three clinical trials, CeraBloom™ supports the organisms on your skin that naturally make the ceramides your barrier needs to stay strong, calm, and resilient.

If you want skincare that works with your skin biology—not just on top of it—CeraBloom™ is the breakthrough.


Your microbiome is the community of bacteria, single-celled organisms, and viruses that live on your skin and are nearly everywhere!
