Skin longevity, taken daily

Skin aging
is just a condition.

A treatable one. Eight clinically-studied actives in one pineapple shot, daily. You'll feel something within a week. The longevity work happens underneath — over months.

The only formulation
that does this

Skin doesn't age on one mechanism.
We didn't formulate for one, either.

Most ingestibles solve one thing — collagen, or glutathione, or hyaluronic. But skin loses tone, barrier, structure and oxidative defense in parallel. glo is eight clinically-studied actives, organized into four functional complexes, each dosed to where the evidence actually is.

What you'll notice.
And when.

Most longevity supplements ask you to wait three months on faith. We won't. There's a real, early signal — and a slower, structural change underneath. Both are measured. We'd rather you know which is which.
Day 5–7
What you'll feel first
An early signal.
Skin holds makeup differently. Looks brighter under indoor light. Feels smoother under your fingers. The barrier rehydrates first — and that changes how light reflects off your skin.
The mechanismHyaluronic complex restores stratum-corneum hydration. Glutathione drops the immediate antioxidant load. Light reflectance shifts. Real, but it's the surface — not the structure.
Week 4–8
What others will notice
A visible change.
Tone evens out. Pigmentation drift starts to settle. The barrier holds water through the day instead of needing reapplication. People who haven't seen you in a month start asking what you've changed.
The mechanismTyrosinase regulation kicks in (glutathione, white tomato, niacinamide). TEWL drops measurably. Melanocyte activity quiets. Visible to the eye, measurable to the Corneometer.
Week 12+
What's happening underneath
The longevity work.
Dermal collagen density. Elasticity recovery. Cumulative oxidative defense. The part you don't see in the mirror — measured by Cutometer, 8-OHdG, collagen echo density. The part longevity science actually cares about.
The mechanismCollagen peptide stimulates fibroblast Type I synthesis. Astaxanthin protects membrane lipid from peroxidation. Niacinamide feeds NAD⁺. Measured in months, not days.

Most ingestibles either chase the early signal (and lose all longevity credibility) or hide it (and lose all retention). We'd rather be honest about both. The early signal earns you the first week. The longevity work earns you the years.

How we got to this exact formulation

Eight specialists.
One computational backbone.

Getting eight actives to cooperate at trial-grade dose is not a clinical question — it's a combinatorial one. Too many variables for ten clinicians to brute-force. So we did what AI-driven biotechs do: we used the tools.

Every dose, ratio, and interaction in glo was simulated against published trial data — then reviewed, adjusted, and signed off by the MDs. The computer narrowed the search space. The clinicians made the calls.

800Kdata points
01 · The dataset
Clinical trial data, indexed.
Published dose-response curves, bioavailability studies, and interaction data across the eight active ingredient families — pulled from peer-reviewed literature and structured for computational search.
3Bsimulations
02 · The search
Three billion combinations, modeled.
Dose, ratio, MW fraction, absorption window, drug-drug interaction matrix. Three billion configurations simulated to surface the small set worth clinical review.
8MDs · 4 yrs
03 · The judgment
Then clinicians chose.
The simulation surfaced candidates. The 8-specialist collective — 6 MDs (Korean clinicians + 1 US dermatologist) and 2 PhDs (skin reverse-aging research, Seoul + US) — reviewed, adjusted, ran patient-side validation, and signed off. AI is a fast literature search, not a doctor.

This is what AI in longevity actually means. Not "AI-generated supplements." Not a chatbot writing dosages. A computational tool that lets ten clinicians do four years of dose-calibration work in months — and lets us prove, with receipts, that every milligram on the label sits in the published evidence range.

The clinical collective behind glo

Eight specialists.
One protocol.

glo was developed by eight specialists — five Korean MDs (board-certified dermatologists and plastic surgeons in Seoul) plus one US dermatologist, alongside two PhDs in skin reverse-aging research (Seoul + US) — each with 10+ years in the field.

01 · Why eight
4×8
Four mechanisms.
Eight actives.
Skin ages along four parallel pathways. Each active in glo is chosen for one — and dosed to the lower bound of the evidence-supported range.
02 · The dose

printed.
Calibrated to
the trial.
Every milligram printed on the label, matched to what published clinical trials actually used. No proprietary blends, no hidden math.

specialists.
6 MDs + 2 PhDs.
Six MDs (Korean dermatologists + plastic surgeons in Seoul + 1 US dermatologist) and two PhDs in skin reverse-aging research (Seoul + US) — each with 10+ years in the field. Korea's surgical-grade clinical discipline meets US-published research evidence.
"

I've taken collagen, glutathione, and hyaluronic separately for years. glo is the first time someone put all four mechanisms in the same room — and dosed them like they meant it.
