§ The first pillar
Protocols.
The medicine, not just the laser.
The protocol library is the proprietary clinical IP at the center of the Precise System. Indication-specific frameworks engineered for Fitzpatrick I through VI — including the darker skin types the industry has historically struggled to treat.

A laser without protocols is a tool without instructions.
A protocol is not a setting. A protocol is a clinical framework. Patient assessment, indication identification, parameter selection, energy application sequence, biologic control coordination, and follow-up — together — define how a treatment is delivered and why it produces the outcome it does.
Most laser systems sell parameters. Energy, pulse width, spot size, repetition rate. The practitioner is left to translate those numbers into clinical decisions, calibrating against patient skin type, indication severity, prior treatment history, and a dozen other variables. The result is wide variance in outcomes for the same equipment.
The Precise System sells protocols. Each protocol is a complete clinical decision tree authored by the clinical leadership and continuously refined through aggregated outcomes from the practitioner network. Parameters are downstream of the protocol — they are how the protocol is executed, not the protocol itself.

Inside the protocol library.
The library covers the indications most central to laser dermatology, with explicit parameter envelopes and biologic control coordination for each. Categories below are representative— the live library updates continuously as new protocols are authored and existing ones are refined.

How a protocol is built.
Each entry in the protocol library is a complete, executable clinical framework. The components are not optional. Removing one does not give you a partial protocol — it gives you a parameter set that cannot reliably produce the indicated outcome.
Indication and patient assessment come first: Fitzpatrick type, indication severity, prior treatment history, contraindications. Parameter envelopes follow: wavelength selection, fluence range, pulse duration, spot size, repetition rate, and the safe adjustment ranges for each based on patient assessment.
Treatment sequence governs spacing between sessions, expected response milestones, and decision points for parameter adjustment. The required biologic control regimen is integrated directly: prep before the session, recovery in the critical window after, maintenance between treatments. Outcome capture is structured — the practitioner logs treatment results in the practitioner portal, which feeds the Data Intelligence Layer.
Continuous refinement closes the loop. Aggregated outcomes surface parameter adjustments, biologic control optimizations, and protocol updates. Approved updates push to the library and to every practitioner using the system.
§ The flagship
The PIH Prevention Protocol™.
Post-inflammatory hyperpigmentation is the wedge. PIH is the most common — and most under-acknowledged — complication of laser treatment in skin of color. The same energy delivery that produces clean clearance on Fitzpatrick I–II can trigger weeks or months of hyperpigmented response on Fitzpatrick III–VI. The industry’s default response has been to under-treat or not treat at all.
The PIH Prevention Protocol™ was engineered for the full skin-type spectrum from the first patch test. Conservative energy envelopes calibrated to Fitzpatrick III, IV, V, and VI; mandatory prep regimen to stabilize melanocyte response before treatment; recovery regimen tuned to suppress inflammatory cascade in the critical 72 hours; structured outcome capture at scheduled follow-ups to surface emerging pigment shifts before they progress.
The result is a protocol that produces predictable clearance with dramatically reduced PIH events compared to standard pico frameworks — on the patient population the industry was historically least able to serve.
The protocol is not the laser. The laser executes the protocol.
