KIND TO BIOME heart mark

Microbiome-first is becoming the price of entry

The skin microbiome is now understood as central to skin health, and "kind to the microbiome" has moved from a nice-to-have to something retailers and consumers increasingly expect brands to prove. At the same time, the science has matured: properly formulated products can respect the microbiome, and advanced formulations can go further and modulate it, but each of those is a different claim, requiring a different level of evidence.

That's the gap we exist to close. We turn microbiome science into evidence you can put on a product, and defend.

We match the evidence to the claim

Not every microbiome claim needs the same proof, and using the wrong evidence either wastes budget or won't stand up. It's why we built two complementary tiers, and why we're one of the few partners that offers both.

Tier 1 — Say it's kind to the microbiome, and prove it.

Our in-vitro + ex-vivo certification substantiates non-modulating claims — that your product respects and does not disturb the skin microbiome i.e. that your product is “microbiome friendly”. Controlled and reproducible in 2–3 weeks. These are defensible microbiome claims a cosmetic can make today.

Tier 2 — Make a breakthrough claim, and back it with human data.

When you want to claim your product actively modulates the microbiome, that's a bigger claim, and it needs in-vivo evidence. Our clinical studies on real, condition-matched volunteers, read with sequencing, generate the data breakthrough claims require.

The KIND TO BIOME Seal

Independent, third-party assurance that a product, or a raw material, is gentle on the microbiome of the area of application. Our unique in-vitro + ex-vivo protocol accounts for a significant and defensible part of the microbiome in any given body area, testing your product across four phases from microbiological purity to real, human-derived community balance.

Advanced clinical microbiome studies

When you're making an innovative or breakthrough claim, sequencing is a commodity, the value is in the recruitment and the interpretation. We run in-vivo studies on real, condition-matched volunteers and turn the data into a defensible answer: what your product did to the skin ecosystem, whether it holds up, and which claims it supports.

A recruitment platform that de-risks the study.

A screened, profiled panel of 1,500+ volunteers, sampled in-lab by professionals, because how a sample is taken can change the result as much as the product.

Interpretation, not a data dump.

Compositional-aware analysis and plain-language readouts, built to substantiate claims. We go ahead and issue a conclusion to your study report.

Strain-level resolution.

Full-length 16S + ITS (bacteria and fungi) on long-read sequencing, resolution that sees what genus-level data misses.
