Why is CO2 laser used in laser skin resurfacing?

Carbon dioxide laser energy is absorbed by water in skin cells. A clinician can use it to vaporise a thin surface layer or create separated treatment columns, depending on the goal. This controlled injury prompts repair, which may soften fine lines, rough texture, selected scars, and some sun-related changes. The treatment does not make every mark disappear, and results depend on the condition treated and the depth chosen.

A consultation should distinguish resurfacing from treatments aimed mainly at colour, vessels, or active inflammation. Skin tone, a tendency to form thick scars, recent tanning, cold sores, and medicines can change the plan and the safety precautions.

Share your full skincare and medication list, including products that irritate or thin the skin, and mention any history of cold sores or difficult healing. Use the prescribed preparation if one is given and avoid tanning. During recovery, keep the area moist with the recommended dressing or ointment, cleanse gently, protect it from sunlight, and avoid picking, scrubbing, heat, and swimming until the surface has closed.

Ask the clinic to review worsening pain, expanding redness, pus-like drainage, fever, or a foul smell. Urgent assessment is needed for swelling that interferes with breathing or eyesight. Persistent changes in colour, new blisters, or delayed healing should also be reported rather than covered with unapproved cosmetics.

Ask whether fractional or fully ablative resurfacing fits your concern, what depth is proposed, how long the treated surface may need protection, which products to pause, and how pigmentation risk will be managed for your skin tone.
