A CO₂ laser procedure (commonly used for skin resurfacing) can be very effective—but it’s not something to take lightly. The laser removes layers of skin, so proper precautions before and after are essential to avoid complications like infection, scarring, or pigmentation changes.
Eye Protection (Non-negotiable)
Everyone in the room must wear wavelength-specific laser goggles
Patient uses metal corneal shields (for peri-orbital treatment) or protective eyewear
CO₂ lasers can cause instant retinal or corneal damage.
Proper Laser Settings
Choose appropriate power, pulse duration, and density based on skin type and indication
Start conservative, especially in darker skin tones (to avoid hyperpigmentation or burns)
Avoid overlapping passes unless specifically required.
Fire Safety Measures
No oxygen flow near the treatment field unless necessary
Use wet gauze around treatment areas if needed
Keep a saline bowl or fire extinguisher nearby.
Smoke Evacuation
Use a smoke evacuator with HEPA filter
Laser plume contains:
Viral particles (e.g., human papillomavirus in wart treatments)
Toxic compounds
Staff should also wear masks designed for plume protection.
Maintain Sterility
Use sterile tips or properly disinfected handpieces
Wear gloves and follow aseptic technique
Prevents post-procedure infection.
Bottom line
During a CO₂ laser procedure, the biggest risks are:
Burns / scarring
Eye injury
Infection
Fire hazard
Toxic plume exposure
All precautions are about controlling those risks.
