How It Works · The Bloran Method
90 seconds at home. 72 hours to a regimen that’s actually yours.
Bloran begins with a CLIA-validated at-home skin microbiome and barrier test — no clinic visit, no guesswork — then pairs it with a compounding lab in Boulder, Colorado that ships a personalized 8-week regimen, dosed to your skin’s actual read.

The Bloran Method · Four chapters
Four chapters, one compounding lab. What actually happens between the kit arriving and your first dose.
We did not want “personalized” to mean a multiple-choice quiz. So we built a four-phase clinical service — collection, analysis, clinician review, compounding — that takes place across 72 hours, in one building, under one accountable team.
-
01
At-home collection · day 0
A single-use microfluidic cartridge collects a small skin sample from your cheek and jawline in 90 seconds. Pre-paid mailer returns it to our Boulder facility in temperature-controlled packaging. No clinic appointment, no fasting, no blood draw.
-
02
Lab analysis · day 1
The sample enters our CLIA-validated pipeline: barrier integrity, ceramide profile, microbiome diversity, and inflammatory markers — quantified against the reference cohort of 14,200+ prior readings. A 23-axis skin fingerprint is generated.
-
03
Clinician review · day 1–2
A board-certified dermatologist on our 22-person clinical advisory board reviews every flagged fingerprint before formulation. The result is not a product recommendation — it is a signed-off compounding brief: actives, doses, vehicle, contraindications.
-
04
Compounding & shipment · day 2–3
The brief is dosed in our 18,000 sq ft FDA-registered 503B outsourcing facility in Boulder — every batch traceable from raw API to doorstep in a single record. The 8-week regimen ships in carbon-neutral cold-chain packaging. Most doors by hour 72.

The Facility · Boulder, CO
Inside the Boulder compounding lab where every formula is dosed, traceable, and clinician-reviewed.
Bloran is not a white-label brand. The 18,000 sq ft facility at 1820 Pearl Street, Suite 300, Boulder, Colorado 80302 is registered with the FDA as a 503B outsourcing facility — the same regulatory category as hospital compounding pharmacies. Formulations are batch-compounded on demand, not pulled from a stock shelf.
-
Batch-traceable from API to doorstep
Every active ingredient carries a certificate of analysis. Every batch has a record number. Every shipment references the record number on the label.
-
Small-batch compounding
Runs are measured in days of supply, not months. A regimen for one customer is not the same bottle as a regimen for another.
-
Human derm sign-off on every flag
If the algorithm flags an interaction, contraindication, or out-of-cohort read, a clinician reviews it before compounding begins. The algorithm proposes; the clinician disposes.
Operated by Bloran Dermatology Sciences, Inc. · 87 full-time employees including 22 licensed clinicians and 14 PhD scientists.
Adaptive Refill · Beyond subscription
Your second bottle is not a re-subscription. It’s a re-formulation.
Most personalized skincare stops at the first bottle. Bloran’s adaptive refill algorithm reads the response telemetry from your daily skin diary and re-runs the compounding brief before every refill — so the second batch is dosed to how your skin actually behaved on the first.
01 · Telemetry
Your skin diary, every day.
A 30-second daily check-in logs barrier comfort, hydration feel, flare events, and product reactions. By week 4, the dataset is rich enough to act on — and 71% of subscribers see measurable improvement in their primary concern at this point.
02 · Re-formulation
The brief is rewritten, not re-shipped.
Before your next 8-week batch, the compounding brief is regenerated. An active that worked is held or up-titrated; an active that irritated is swapped; new actives enter the formula as the skin’s tolerance changes. You receive a “what changed and why” note with every refill.
03 · Clinician guardrails
Algorithms propose. Clinicians dispose.
The same 22-person clinical advisory board — 9 of them board-certified dermatologists — reviews any flagged re-formulation before it ships. The refill cadence is every 56 days on average; 84% of subscribers are still active past month 6.
Clinical Advisory · Who is actually behind this
A 22-person clinical advisory board sits between your skin diary and your shipment.
The objection we hear most often is some version of “is an algorithm really making medical decisions here?” The honest answer is no — and the architecture of the service is built to prove it. Every flag is reviewed by a human clinician; 11 peer-reviewed studies back the underlying science; the recent publication in JCAD (March 2024) covers ceramide-restore efficacy for sensitive-skin phenotypes.
