Prove the glow is real.
An ingestible beauty product promises skin from within. Run a cohort on it for eight to twelve weeks and we read the systemic markers that actually drive skin aging — inflammation, oxidative stress, micronutrient status — before and after. A measured shift that stands behind the claim, not a before/after selfie.
The claim at stake
"Beauty from within" needs more than a bottle. Ingestible-beauty claims rest on systemic biology — inflammation, oxidative load, the micronutrients skin is built from. A measured signature before and after is the difference between a glow in a ring light and a claim that holds up.
A glow in a ring light
Before/after selfies, influencer skin and a health-halo — nothing systemic a retailer, regulator or skeptic can check.

A measured systemic shift
The cohort's own inflammatory and oxidative markers, before and after, read into a per-axis delta with significance.
paired · Δ · p-value
A claim you can defend
Substantiation retail buyers and regulators accept — and an R&D baseline for the next formulation or dose.

How the engine applies
One trial's panels in, a signature out. You bring the cohort's before/after lab panels; the engine reads the inflammatory–oxidative axis, computes the paired shift and significance, and returns a Signature Report that backs the claim.
The axis we read
Skin aging is systemic before it is visible. For ingestible beauty, these are the markers that move upstream of the mirror — inflammation, oxidative damage, and the micronutrients skin is built from.
hs-CRP
Systemic low-grade inflammation — a core driver of dullness, redness and accelerated aging.
HS-CRP · IL-6
Oxidative stress
Markers of oxidative damage to lipids and DNA — the load antioxidants are meant to lower.
MDA · 8-OHdG · GSH
Micronutrient status
The raw materials for collagen and barrier function — depletion shows before the skin does.
Vit C/D · zinc · omega-3 index
Glycation (if the window allows)
The cross-linking that stiffens collagen and dulls skin — a trend a longer cohort begins to show.
HBA1C · AGEs proxy
Who this is for
Any brand selling beauty you swallow. If the promise is a systemic effect — skin, hair, nails from the inside — there's a biomarker that should move, and a cohort that can prove it.

Logos shown are market examples of each segment, to illustrate who the application fits — not Zenlo clients or partners, and no endorsement is implied. The fit is the claim type, not the logo.
What this is — and isn't
Evidence for a claim, not a health claim
We measure what moved in a cohort and hand you the trail. We don't manufacture the result, and we don't make medical or cosmetic claims on the product's behalf.
Illustrative application
This page shows how the engine would apply to a nutricosmetics trial.
- No named client or product
- Numbers shown are example endpoints
- The real signature comes from your data
The cohort owns the result
The signature is whatever the panels say — up, down, or flat.
- Paired before/after, with significance
- Drivers named; nothing cherry-picked
- Reproducible from the same inputs
Not a medical claim
A measured biomarker shift is evidence, not a diagnosis or a treatment claim.
- For product substantiation & R&D
- Claims language stays the brand's responsibility
- Zero data retention on model calls
Turn your trial into a signature.
Send one trial's before/after panels and we return a Signature Report: the measured systemic shift, with an evidence trail your buyers and regulators can check.
