What should you know about radiofrequency fractional CO2 laser?

A CO2 laser removes or heats selected microscopic areas of the outer skin while leaving surrounding skin available to support healing. Fractional delivery treats a pattern of small columns rather than the entire surface. This can be used for texture changes, acne scars, fine lines, and some uneven pigmentation, but the setting and depth must be individualised.

The phrase radiofrequency can describe a separate energy technology, so ask the clinic to name the exact device and whether it combines radiofrequency with a CO2 laser. These approaches have different mechanisms, downtime, and pigment considerations.

During consultation, disclose previous cold sores, medicines, recent tanning, active acne, eczema, or a tendency to form raised scars. Follow the clinician’s instructions about skincare and sun protection. After treatment, expect redness, warmth, swelling, peeling, or tiny crusted areas. Use only the cleanser, moisturiser, and sun protection recommended for your healing stage; do not pick flakes or crusts.

Recovery varies with treatment depth and the area treated. Avoid heat, vigorous exercise, swimming, and irritating products until the skin barrier has recovered. Results develop gradually as the treated skin heals and remodels.

Contact the treating clinician promptly if pain, swelling, or redness is worsening rather than settling, or if the area develops spreading warmth, pus, fever, blisters, or significant darkening. Urgent assessment is appropriate for facial swelling affecting vision or breathing. Do not apply unapproved antiseptics or steroid creams over treated skin without advice.

Ask which device and wavelength will be used, what concern it is targeting, how deep the treatment will be, and how your skin tone affects pigment risk. Clarify expected downtime, aftercare products, whether cold-sore prevention is needed, and what symptoms should trigger a review.
