What should you know about fractional carbon dioxide laser?

Carbon dioxide laser energy removes or heats tiny channels of the outer skin and the upper dermis. Untreated skin between those channels helps the treated area heal. This fractional pattern can be adjusted for concerns such as uneven texture, fine lines, acne scars, and some types of discoloration. The result depends on the depth, energy settings, skin type, treated area, and the condition being addressed.

After treatment, redness, warmth, swelling, sensitivity, dryness, peeling, or small crusts can occur. The skin may look darker temporarily as it heals. A clinician should assess active infection, poor wound healing, recent tanning, medicines, and a history of raised scars before treatment.

Before the appointment, follow the clinic's instructions about sun exposure, skincare products, shaving, and medicines. Arrive with clean skin and disclose cold sores, allergies, previous laser procedures, and any tendency to develop lingering pigment changes.

Afterward, cleanse gently, keep the area moisturised as directed, avoid picking flakes or crusts, and protect healing skin from sunlight. Do not restart irritating products until your clinician says the skin barrier has recovered. Recovery varies with treatment intensity and body site; visible redness may settle before the skin feels fully normal.

Contact the treating clinic promptly if pain, swelling, or redness is worsening rather than settling, or if the area develops spreading warmth, pus, fever, blisters, or an unusual odour. Seek urgent medical help for facial swelling that affects breathing or vision. New or persistent darkening, lightening, or scarring also deserves review so treatment can be adjusted or stopped.

Ask which concern the laser is expected to improve, what settings and treatment depth are planned, how many visits may be considered, and what recovery pattern is typical for your skin tone. Clarify who will perform the procedure, which numbing method is used, how to manage a cold-sore history, and when exercise, makeup, swimming, and active skincare can resume.
