Crust Care After Laser: Let It Leave on Its Own
What Crusts Are
The pinpoint crusts after Q-switched/picosecond pigment work and the micro-crusts after fractional lasers are biological dressings — exudate and necrotic debris protecting new epithelium in a moist environment. The whole discipline in one line: let them shed naturally.
Timelines
| Modality | Crusting begins | Natural shedding |
|---|---|---|
| Q-switched/picosecond pigment | Within hours | 5-7 days |
| Fractional CO2 | Within 24 h | 5-10 days (longer at high density) |
| RF microneedling | Pinpoint crusts | 1-3 days |
The Three Don’ts
- Don’t pick: premature lifting tears away immature epithelium — the direct route to scars and PIH.
- Don’t soak: long baths, steam and hot yoga soften crusts off early.
- Don’t cover: no makeup or heavy cosmetics over crusts (physician-directed repair products only).
What Helps
- Keep moist: directed dressings/ointments give smoother shedding.
- Gentle cleansing: water or a specified cleanser; pat, never scrub.
- Mild itch is normal: cool compresses help; intense itch with redness needs review.
FAQ
Is pink skin after shedding normal?
Yes — new skin is pink and fades over weeks; strict sun protection matters most right then.
I accidentally picked one off — now what?
Stop all stimulation, keep it moist with repair products, observe. Persistent redness, indentation or raised tissue should be seen early.
