CO2 Resurfacing Courses: Session Spacing and Course Architecture
CO2 fractional results compound across a course — but only when spacing respects re-epithelialization and collagen remodeling timelines. Stack sessions too early and you treat inflamed skin; too late and momentum is lost.
Spacing by Treatment Intensity
| Session type | Re-epithelialization | Next session |
|---|---|---|
| Light resurfacing (low energy/low density) | 3-4 days | 4 weeks |
| Standard fractional pass | 5-7 days | 6-8 weeks |
| Aggressive scar protocol | 7-10 days | 8-12 weeks |
Course Architecture by Goal
- Texture and tone: 2-3 light sessions at 4 weeks — cumulative smoothing, minimal downtime per visit
- Acne scars: 3-5 standard sessions at 8 weeks, with subcision/CROSS decisions made at the mid-course mark
- Single-event resurfacing: one aggressive pass is legitimate for photoaging in committed clients — schedule away from social events by a month
Course Breaks
PIH-prone skin (types IV-VI) gets a 12-week reassessment gate after every session — proceed only when tone is even and stable. Parameter pairing per session follows the density-energy balance guide, and aftercare runs on the actives resume timeline.
