Session-by-Session Dose Increase

A short placeholder line describing the stepwise dosing ladder.

  • 130 mJ/cm²: Starting dose (placeholder baseline)
  • +10%: Typical increment (placeholder step size)
  • 20–30: Course length (placeholder session count)
  • 2000 mJ/cm²: Ceiling dose (placeholder cap)

Fixed-step escalation rationale

Placeholder sentence on why doses increase gradually each visit.

Tracking the staircase

Placeholder sentence on charting dose history across sessions.

Erythema Check Before Each Increase

A short placeholder line describing the pre-dose skin check.

  • 24–48h: Check timing (placeholder post-exposure window)
  • 0–2: Grading scale (placeholder none/mild/marked)
  • 3 paths: Gate outcome (placeholder proceed/hold/reduce)
  • Visual: Assessment method (placeholder clinician exam)

Why the gate matters

Placeholder sentence on preventing burns via pre-check gating.

Reading the response

Placeholder sentence on classifying redness severity levels.

No Erythema — Proceed With Increase

A short placeholder line describing the clear-skin escalation path.

  • Most common: Path frequency (placeholder typical outcome)
  • +10%: Dose change (placeholder increment applied)
  • Next visit: Next check (placeholder recheck cadence)
  • Low: Risk level (placeholder safety margin)

Confirming tolerance

Placeholder sentence on confirming skin tolerated prior dose.

Applying the step-up

Placeholder sentence on calculating the next escalated dose.

Mild Erythema — Hold Dose

A short placeholder line describing the hold-dose response.

  • Mild pink: Trigger (placeholder erythema grade)
  • 0%: Dose change (placeholder repeat same dose)
  • Delayed: Re-escalation (placeholder waits for clearing)
  • Moderate: Risk level (placeholder caution level)

Repeating the same dose

Placeholder sentence on holding at prior dose until settled.

Watching for recovery

Placeholder sentence on monitoring skin before resuming escalation.

Marked Erythema — Reduce Dose

A short placeholder line describing the dose-reduction response.

  • Marked red: Trigger (placeholder erythema grade)
  • −25%: Dose change (placeholder reduction applied)
  • Yes: Possible pause (placeholder treatment hold)
  • High: Risk level (placeholder safety concern)

Cutting the dose back

Placeholder sentence on reducing dose after marked redness.

Resuming safely

Placeholder sentence on cautious re-escalation after recovery.

Placeholder key-insight sentence on avoiding burn recurrence.
