What should you know about CO2 fractional laser skin treatment?

Fractional treatment delivers laser energy in a grid of narrow columns. Some surface tissue is treated while nearby tissue remains intact, which can support repair. Depending on the plan, the aim may be to improve rough texture, fine lines, uneven tone, or selected scar changes. A consultation is needed to decide whether the concern is suitable and how much energy the skin can tolerate.

The treated area may feel hot or tender and can look red or swollen. Peeling, pinpoint crusts, dryness, and temporary colour change are possible during recovery. Skin can continue to change after the visible surface has settled because collagen remodelling takes time.

Before treatment, disclose tanning, eczema or dermatitis, active acne or infection, cold sores, medicines, and any history of dark marks or raised scars. Do not start or stop prescription products without instructions. After treatment, cleanse gently, apply the recommended bland products, and leave peeling skin alone. Avoid direct sun, heat, rubbing, and unapproved active ingredients while the barrier is recovering.

Use the follow-up plan provided by the treating clinician. Makeup, exercise, swimming, shaving, retinoids, and exfoliating acids may need to wait until the surface has healed. Do not judge the result while redness or swelling is still changing.

Call the clinic if discomfort or swelling becomes more intense, redness spreads, or the area develops increasing warmth, pus, foul drainage, blisters, or fever. Urgent care is appropriate for breathing difficulty, severe facial swelling, eye pain, or any change in vision. A clinician should also review pigment changes that continue to deepen or healing that appears stalled.

Ask what skin concern is being targeted, what degree of resurfacing is planned, whether more than one appointment may be considered, and which aftercare products are suitable for your skin. Confirm the warning signs, review date, and timing for returning to normal skincare.
