CO₂ Laser — Pre-Treatment

Pre-Treatment Protocol for CO₂ Laser Resurfacing

Everything you need to do before your procedure so healing is smoother, risks are minimised, and results are maximised. This guidance supports (not replaces) your clinician’s instructions.

Quick Checklist (Overview)

4–6 weeks before

  • Strict SPF 30–50 daily; avoid tanning & sunbeds.
  • Pause active facials/peels on the treatment area.
  • Disclose all meds/supplements (see list below).
  • If prone to cold sores, tell us (possible antiviral plan).

7–10 days before

  • Stop retinoids (vitamin A), strong AHAs/BHAs on area.
  • Stop waxing/epilation/laser on area.
  • Reduce alcohol; prioritise hydration and sleep.

24–48 hours before

  • No strenuous exercise, heat exposure, or saunas.
  • Have bland cleanser, occlusive, SPF ready at home.
  • Arrange transport if having numbing/sedation.

Important: If you develop illness, active infection, open lesions, or have had recent significant sun exposure, contact the clinic—your date may need moving for safety.

Candidacy & Fitzpatrick Guidance

Who may need to defer

  • Pregnant or breastfeeding.
  • Active acne, dermatitis, or infection in the area.
  • Recent isotretinoin (typically defer 6–12 months; clinician will advise).
  • History of keloid/hypertrophic scarring (risk/benefit discussion).
  • Photosensitising meds (see list below) without clearance.

Skin tone considerations

All treatments are individualised. Higher Fitzpatrick types (III–VI) may require gentler parameters, extended prep, and stricter post-care to reduce PIH risk.

  • I–II: Standard prep; strict sun avoidance.
  • III–IV: Consider 2–4 weeks of pigment-calming topicals; slower parameter build.
  • V–VI: Conservative settings, extended prep, and close follow-up; alternative modalities may be advised for some concerns.

Medications & Supplements to Flag

CategoryExamplesNotes
Retinoids / exfoliants Topical tretinoin, adapalene; strong AHAs/BHAs Stop 7–10 days pre-treatment unless told otherwise.
Systemic retinoids Isotretinoin Often defer 6–12 months; clinician decides.
Photosensitisers Doxycycline, minocycline, some diuretics, St John’s wort May increase sensitivity; disclose for timing adjustments.
